Introduction
System Overview
The FS-03 system is a complete solution for high quality group teleconferencing. The system maintains exceptional audio quality in small to large conference spaces and provides multiple inputs for program sources. The FS-03 uses digital signal processing to realize the sound quality of CTG’s teleconferencing microphones, and to maximize intelligibility.
The FS-03 Advanced Teleconference Interface ships pre-configured for CTG ceiling and/or table microphones with eight stored configurations that will satisfy most room situations. The presets are recalled through the Logic Input connection to allow configurations for various room conditions, and A/V integrations. The pre-calibrated state of the FS-03 enables any installer to reach the same performance results. For a description and specific use discussion of the eight presets see pages 15-17. CTG software is available for configuring the FS-03 in difficult or unusual situations not covered by these presets.

Room Evaluation
The FS-03 system uses digital signal processing with proprietary high quality teleconferencing microphones to be effective in virtually any conference space. Microphone selection and placement should be based on the coverage area required in the room as well as the acoustical characteristics of the room.
Ceiling Based System
Ceiling Requirements
The benefits of the CTG ceiling microphones make them a preferred choice. These microphones will offer the highest level of performance when installed in an acoustic drop ceiling no higher than 10-feet.
Optimum performance in acoustic drop ceilings
Ceiling height should not exceed 10 feet
Noise Sources
Unwanted noise will distract the far end of a teleconferenceteleconference and compromise intelligibility. Common ceiling noise sources include HVAC and projectors. Any conference room should have a low noise level allowing people to speak to each other comfortably in the room, as well as while teleconferencing.
• HVAC noise typically results when a high velocity of air is forced through a small opening. Often the heating/cooling system may be quieted while maintaining a comfortable climate. While CTG employs several techniques to electronically reduce noise, proper microphone placement is an important consideration.
• Airflow from a vent should not blow directly on a microphone
• Try to keep at least 3 to 6 feet between an air vent and a microphone
• Microphones should be spaced a minimum of 8 feet apart
• Projector noise will produce the same unwanted effect as HVAC noise. The same consideration should be used with projectors as discussed above for noisy vents. Most manufacturers’ specify the noise rating in dB of their projectors. If practical, avoid placing microphones near projectors or their cooling fans.
Conditions for Ceiling or Table Microphone Systems
The chart below illustrates the sensitivity of the human ear to sound intensity as a function of frequency. Noise is usually specified in terms of Noise Criteria (NC) levels.
The recommended NC range for conference rooms is 35 to 45. The lower NC the better for good intelligibility. This results in noise that, within the frequency range of human speech, is easily over ridden at normal conversational levels.
Conversational average speech levels are about 70dB. If the maximum ambient noise in a room, in the frequency range of speech, is 45dB or less a speaker’s voice will be 25dB or more above the noise level and be easily heard by others in the room and at the far end of a teleconference.
The shaded area indicates an acceptable noise level for optimum teleconferencing.
If the noise level is high enough to distract the Conference the following steps may be taken to minimize or eliminate the effect:
✓ The noise source may be examined to determine if it can be reduced or eliminated
✓ The FS-03 has presets that adjust the equalization to address acoustically challenging rooms
(See page 15, Presets 2 and 4)
✓ People may cause unwanted noise that will interfere with the intended voice transmission during a conference. These noises may be such things as paper shuffling, pen or keyboard tapping, side conversations etc. The FS-03 system has several techniques for minimizing these distractions:
• The FS-03 provides automatic gating of microphones so the number of open microphones is reduced. Only those microphones close to the intended speaker will be on
• Presets are provided for presenter/audience environments that allow the presenter only transmission and can be switched to open the entire room for question and answer sessions.
Activation of these modes may be as simple as a switch on a wall plate connected to the FS-03 (logic inputs) or through a control system (RS-232).
Reverberation
Reverberation is the reflected sound that exists in a room after the sound source has stopped. Reducing the amount of reverberation transmitted to the distant end is also important in maintaining good intelligibility. A room should have an RT60 of less than 0.6 seconds for good intelligibility.
RT60 is the length of time it takes for reflected sound to decrease to one millionth of its original intensity (-60 dB). Surfaces in a conference room that absorb sound are typically an acoustic drop ceiling, heavy drapes, carpet, wrapped fiberglass wall panels, soft furniture, and people. Locating microphones in domed ceiling areas should usually be avoided. For rooms that are highly reverberant consideration should be given to treatment with acoustical panels or other sound absorbing materials. Additionally, the FS-03 has settings which aid in reducing the effect of reverberation.
(See page 15 Presets 2 and 4)
Room Coverage
Establishing the number of microphones used in a system should not be determined by the size of the room but by the coverage area. This is the area where people will be located while participating in the conference. CTG microphones typically cover an area with a radius of 5 to 10 feet from the microphone location.
Typical Configurations – drawings show microphone and speaker locations
Installation of CTG Microphones and Speakers
Tools Required for Installation
The following tools are recommended for the installation of the ceiling components and setup:
• ½ inch drill – for drilling through an acoustic tile, a perfect hole will be made for the CM-01 ceiling microphone
• Hand saw – the ceiling speaker enclosure requires a 6 3/8-inch hole
• Wall snake – in most rooms, cables will need to run down through a wall and terminate at the FS-03
• Wire nuts – for ceiling speakers
• Wire Stripper
• Small blade screw driver – often referred to in the industry as a “tweaker”
• Ladder
• CTG Preset Switch (optional) – This switch (WP-02 available though CTG) connects to the Logic Input connector on the rear panel of the FS-03. The switch selects between two stored configurations. A momentary manual closure to ground (Pin 9) may also be used to switch among presets
General-CTG Microphones
CTG microphones are true 360° Omni directional. They are electret condenser boundary microphones. The microphone itself should be flush mounted in a boundary of at least 12” in diameter. The element in the tabletop microphone (TM-01) is mounted in a base designed to acoustically couple to the table surface and provide an adequate boundary.
* Each microphone must connect directly to the FS-03 with a “homerun” connection.
Wiring for Microphones (CM-01, TM-01, TM-02)
A connection module (MCM-101) is supplied with each microphone.
On the MCM-101 is a four position Phoenix Terminal Block.

Table Implant Microphone (TM-02) Mounting Detail:
Table Top Microphone (TM-01) Mounting Detail:
SP-01 Ceiling Speaker Module
The speaker enclosures supplied will require a 6 3/8-inch hole in the ceiling material.
The speaker grills are supplied with the speakers already mounted and attached to the enclosures with torsion springs inserted into clips inside the enclosure. To remove the grille simply pull it away from the enclosure and compress the springs to detach.
To simplify installation CTG attaches a twelve-inch wire to each speaker terminal so that it may be connected with wire nuts. The red wire is positive.
(Note: Blind mounts are available from CTG for dry wall ceilings or ceilings with inadequate space above. Tile bridges are also available as an option.)
FS-03 Advanced Teleconference Interface
The FS-03 is designed as a proprietary control unit to power CTG microphones and speakers in teleconferencing applications. The FS-03 replaces the need for a separate microphone mixer and speaker amplifier with an all in one design. The gated microphone auto-mixer, signal enhancements and all internal levels are pre-calibrated and optimized for CTG microphones and teleconference operation.
1. Master Speaker Level: This control adjusts the output of the integrated amplifier and affects all speakers connected to the FS-03. This should be a “set & forget” level for teleconferencing purposes.
2. Power Connection: The power transformer provides 27 Volts AC to theFS-03, and is detachable via a 5-pin DIN connector. The FS-03 has two internal ‘self-resetting’ fuses (there are no user serviceable parts inside the unit). If the internal fuses are triggered, they will re-set after a short period.
3. Speakers 1-6: Each speaker requires a “homerun” connection to the FS-03. The speaker outputs are designed for the CTG SP-01 speaker module. Other 8-ohm speakers may be used to obtain higher performance with program audio sources such as DVD players or other high fidelity devices.
4. Amplifier Remote Level Control: The amplifier remote volume control is for adjusting the internal amplifier of the FS-03 remotely. This level adjustment is typically used to raise or lower the volume of program audio sources.
5. Teleconference Out (to codec): This output feeds a line level input of a codec. The corresponding level trim pot may be adjusted to assure the proper send level is transmitted to the far end(s) of a video call.
6. Teleconference Out (to telephone interface): This output feeds the line level input of an audio telephone interface. The corresponding level trim pot may be adjusted to assure the proper send level is transmitted to the far end(s) of an audio call.
7. Teleconference In (from codec): This input connects to the line output of a video codec. This level may be adjusted with the corresponding trim pot.
8. Teleconference In (From telephone interface): This input connects to an audio telephone interface. This level may be adjusted with the corresponding trim pot.
9. Link Port: (RS-232 control): The link port provides common control of multiple FS-03 systems. To enable this feature the link button must be depressed (in) on the primary FS- 03. The Link Port of the primary FS-03 connects to the Serial Port of the second FS-03.
10. Serial Port: (RS-232 control): This 9-pin Sub-D (male) connector provides an RS-232 serial port for remote control via third-party control systems.
11. Logic Inputs: This 9-pin Sub-D (female) connector provides eight logic inputs for recalling presets stored in the FS-03 via contact-closures. The logic inputs are used to recall factory-stored configurations.
12. Logic Outputs: This 9-pin Sub-D connector provides logic outputs from Channels 1-8. Logic Outputs may be used to control external switching circuits, such as relays.
13. Expansion Ports: The expansion ports permit two FS-03 control units to be linked together and function as one system for larger rooms. The Link Ports may also be used for control of both units through a single device.
14. Auxiliary Input (Looped to speakers): These line level inputs are designed for program audio sources to be heard locally in the room and will also be sent to the distant end(s) of a teleconference.
15. Channels 1-8: Channels 7 & 8 are assignable to mic or line level through the logic inputs. (Please see chart P.15) Up to eight CTG microphones may be connected to the FS-03 when these channels are set to mic level. Line level devices will be heard locally in the room and will be sent to the telephone interface and/or video codec.
****** Channel 1 is assigned as the chairman microphone and does not gate off ******
Choosing a Configuration
The FS-03 ships pre-configured with 8 configurations accommodating various room conditions and peripheral equipment.
Preset 1 (default): This preset provides connection for up to 8 CTG microphones and 2 auxiliary devices. The microphones will sound extremely natural taking full advantage of 7K and 14K audio compression.

|(Pins 1~8) Logic Inputs 1~8; |
|(Pin 9) Ground. |
|******A momentary closure of pins 1~8 to ground pin 9 will switch presets. |
Logic Outputs
The FS-03 provides eight logic outputs on the rear panel 9-pin Subminiature D (male) connector. Logic Outputs can be used to control external switching circuits (such as relays) for cameras, indicators, etc.
Each logic output corresponds with a channel as illustrated below:
RS-232 Control
The FS-03 has an RS-232 Serial Port which allows it to be controlled by a third party control system. The FS-03 Serial Port transmits serial data on pin 3 (TxD), receives serial data on pin 2 (RxD), and provides a ground on Pin 5. The Data Terminal Ready (DTR) & Request To Send (RTS) output signals are connected to the +12 Volt power supply (through a resistor) and are always asserted when the FS-03 power is on.
The FS-03 only requires receive data (pin 2), transmit data (pin 3), and signal ground (pin 5) to be connected for successful data communications A crossover serial cable is required (see cable diagram below).
The FS-03 is programmed for the following serial commands:

Serial Port Data Communications Parameters
The FS-03 communicates through the Serial Port at the factory-selected rate of 38400 bits per second, with 8 data bits, 1 stop bit, and no parity. The FS-03 utilizes a subset of the standard 7-bit ASCII character set. The eighth data bit of each character (the most significant bit) should always be 0.
Link Port
The 9-pin Sub-D (female) connector on the FS-03 rear panel provides the RS-232 compatible serial interface signals used for linking two FS-03 control units within a system. The Link Port of one device simply connects to the Serial Port of the next device. (See diagram below).
Multiple FS-03 control units may be connected together and addressed individually. When multiple units are used, each unit is assigned a unique "Device #". Normally, both units would react to control button commands. However, commands may be sent to specific units by preceding each command with a "device select prefix" character (see below). Only those units whose Device #s are specified will respond to the command that follows. If a command is not preceded by a device select prefix character, then both units will react to that command.
Combining FS-03 Control Units
Two FS-03 control units may be combined for a single room application for a maximum of 16 CTG microphones. When combined the master FS-03 will monitor microphone activity to maintain high performance during teleconferencing. Presenter preset 7 and Q&A preset 8 are strongly recommended to control unwanted side conversations typical in larger spaces.
Expansion In & Out
These 6-pin mini-DIN connectors are for linking two FS-03 control units to expand a system up to 16 microphones. To link a FS-03, simply connect the cable from the Expansion Out jack of the first FS-03 to the Expansion In jack of the second FS-03. The second FS-03 (with no Expansion Out jack connection) becomes the ‘master’. The ‘master’ collects audio signals & control data from the other
FS-03, which becomes a ‘slave’.
Troubleshooting Guide
General:
System installers are urged to contact CTG support when adjusting the system to take advantage of free technical support and have the comfort of knowing the system is functioning optimally. CTG’s support is equipped with video, which can add an additional dimension when aiding with a system installation.
Frequently, when a system does not function as expected, it is due to poor connections between components of a system and/or faulty cables. These would be initial areas to inspect.
Typically when speaking into a CTG microphone nothing will be heard from the local speakers. This is normal as the sound is being sent to the distant end. Specific settings are used for those situations where it is desired to have sound from the local speakers such as program audio, presentations etc.
Based on support calls these are some of the more common problems and suggested solutions:
• Audio is not heard at the distant end
Use a short length of cable to connect the Teleconference Output directly to the Teleconference Input port on the back of the FS-03. If you can hear room sounds (usually accompanied by feedback) in the room speakers, the microphones, mixer circuits and the speaker amplifier are all working. Look for a problem with the cabling, or the teleconference interface.
• Distant room hears audio but complains the levels are too low
Adjust send level (clockwise) for teleconference out “to codec” or “to telephone interface” on back of the CTG teleconference interface.
Test each microphone in the room to determine they are on.
• Local room cannot hear distant end participants
Make sure the input and output cables are not reversed at either end. The output from the FS-03 must connect to the input of a video codec or telephone interface, and the input to the FS-03 must connect to the output of the video codec or telephone interface.
Examine the volume control knob on the front of the FS-03 to determine it is not turned all the way counterclockwise.
• The distant end complains of hearing echo or feedback
Your send or receive levels may be set too high for the echo canceller to function normally.
Connections between the FS-03 and the codec or telephone interface may be connected to jacks that are not routed through the echo canceling circuit.
Speaker and microphone cables may be run in intimate proximity to each other resulting in induced crosstalk. High and low level signal cables should not be bundled together or routed close together through the same conduit for any significant distance.
• The microphones are picking up excessive room noise
One or more microphones may be placed too close to a noise source such as an HVAC register, projector, or other device having a loud fan.
The send (output) level may be set too high on the rear of the FS-03 increasing the microphone sensitivity level. This is masked by the Automatic Gain Control of the codec or telephone interface which reduces the overall volume while the microphones continue to pick up excessive ambient noise. The output potentiometer should be turned down until all or most of the ambient noise disappears without the loss of adequate voice pickup.
