B5DM524Wireless Microphone

Preliminary Operating Instructions Telex Model TT-16 Transmitter Carefully unpack your IFB Transmitter. If there is any damage or shortages, please refer to the “Warranty Service Information”. Set-up Instructions: Power: Power will be received from the supplied “wall cube”. Before applying power, it is suggested that all input cords be plugged in and the antenna be screwed onto the transmitter. Insert the cord plug into the transmitter before plugging in the wall cube. The wall cube normally supplied is for 120 V AC, 60 Hz use only. Transmitter Location: Select a suitable location for the transmitter. Try to keep a clear, unobstructed path between the transmitter and the receiver. The transmitter should not be located near metallic objects such as building structures and file cabinets. Locating the transmitter on top of a file cabinet is OK. Avoid high heat sources such as radiators . Antenna : The antenna supplied should be the only antenna used with the TT-16. The antenna is designed to operate in the vertical position. Audio Input : One or both of the audio input connections can be used at the same time. A single modulation limiter serves both inputs. If either input is not used, that input should be “turned off”. Unbalanced only audio sources devices should be plugged into the ¼ in. (quarter inch) Unbalanced Audio input jack located on the rear panel. Tip is “hot” and the barrel is ground. Balanced or unbalance devices should be plugged into the “XLR” jack located on the rear panel. Pin 1 is Common (or ground), Pin 2 and Pin 3 are audio inputs that depend on the type of intercom selected (RTS 1, RTS 2 or Telex). E.D.R. audio : The Telex TT-16 Transmitter is equipped with E.D.R., Enhanced Dynamic Range (companded) audio. This mode greatly improves the Audio Signal to Noise Ratio when the TT-16 is used with the Telex Model TR-16 receiver. The E.D.R. mode must be selected on the transmitter and receiver to be effective. Also, The E.D.R. Mode must be de-selected if the TT-16 is used with older equipment such as the TR- 34 receiver. Telex TT-16 Transmitter Page 2 Frequency/Channel Considerations: As with any radio device, interference can occur at any time. The frequencies offered are shared with other legitimate users. Check the frequency/channel with the matching receiver to see if any interference is present. If interference is present, choose a different channel. The severity of interference varies with location and distance to the interfering station. If the interference is weak on all channels, this is probably acceptable since your transmitter will cover the interference and is unlikely to interfere with other users. Multiple Channel Systems require other considerations but each channel should be checked as above. For best results, locate each transmitter in the area it is to service, and as far apart as possible. Transmitter Operation: Turn the Monitor control down (counter-clockwise). Now that you have checked all of the channels you intend to use, apply power to the transmitter by pressing the Power Button located on the front panel. The Display Screen should now be on. Select the RF Channel on the transmitter to match the receiver channel. Turn the program material on (balance and/or unbalance audio input). Adjust the appropriate Audio Input Level control until loud program material causes the audio level meter to hit 0 dB. This allows sufficient “headroom” to prevent peak distortion on loud inputs. Set the High/Low power button to High position initially. Audio Monitor: After the audio input levels have been adjusted in the above procedure, stereo headphones with a ¼ in. plug can be plugged into the Monitor jack. If you wish to monitor the audio program material, turn up the monitor (volume) control to the desired level. The monitor control does not affect the transmitted audio level. System Walk Through: Now that the transmitter is set up, you should be able to hear the program material on the appropriate receiver. Walk the receiver through the area that it is intended to be used in. Check for any noise or interference that would cause undesired operation. Some of the causes of poor performance are listed below. Poor transmitter location. Poor receiver location. Interference. Local AC Line noise. RF “Trouble Spots.” Operating distance beyond system capability. Telex TT-16 Transmitter Page 3 Operating Instructions: When the Power button is pressed, the Channel, Frequency, TX power level, existing audio level settings and intercom type are displayed. After this point, switch functions as follows: Operation Function/Result Press set Channel (“blinks”) flashes. Press up (arrow) Channel increments. Press down (arrow) Channel decrements. Press set Flash stops, Channel is set in memory. Press set RF Power High flashes Press up High power Press down Low power Press set Flash stops, Level is set in memory.
