User manual AUSTRALIAN MONITOR TX8201

[. . . ] The input sensitivity when in the line level position is 330mV (for a 1 Volt output) Stereo Line Gain: The 2 auxiliary input channels are labeled Stereo Line 7 and Stereo Line 8. These controls should be adjusted to provide the required mix level for each individual auxiliary channel. Start with the controls set to Level 0 and turn the controls clockwise until the desired mix level for each channel is reached. The sensitivity of auxiliary inputs 7 and 8 is 180 mV (for a 1 volt output). Master Left and Right Output The master Left and Right controls should be adjusted to set the overall mixer level for each output channel based on the individual levels already set via the input channel gain controls. [. . . ] Reading from Left to Right across the rear panel, the connections are for auxiliary inputs 8 and 7. XLR Microphone/Line Inputs Each XLR input is switchable to be either balanced mic or line (via an internal dip switch, the location and setting of which is explained in the `Internal Adjustments' section of this manual). When set to mic level, the mic input sensitivity is 1mV ( for a 1 Volt output). When set to line level, the input sensitivity is 330 mV (for a 1 Volt output). Pin connections are: pin #1-earth; pin #2-active (high, +); pin #3-active (low, -). Phantom power of +15 volts is available on all 6 XLR inputs. An internal phantom power ON-OFF switch is provided for each channel. The default setting is ON (See the `Internal Adjustments' section of this manual for more details). Direct Outputs A unique feature of the TX8201 is the individual direct output available for each of the first 6 channels. The direct outputs are accessed via balanced TRS 1/4" sockets for each channel. The level of each output is 1 Volt (nominal). Internal jumpers (JP1) allow signal from any of the first six channels to be disconnected from the main left/right outputs (See the `Internal Adjustments' section of this manual for more information). The direct outputs are adjustable to be pre or post the channel level control. Factory default setting is post fader. Vox Muting Priority muting is provided for channels 1 and 2. Both channels have equal priority and will mute channels 3-8 when signal is present. The muting function may be disabled by moving the jumper labeled JP2 (located on the pcb behind the channel 8 volume control). ON and OFF positions are clearly indicated on the pcb beside the jumper. The unit ships from the factory with muting enabled (JP2 OFF) ­ that's right, OFF; it is a muting disable function, not a muting enable function. When channels 1 and 2 are disconnected from the main left/right outputs, the muting function is automatically disabled. Tone Generator A four tone generator is built into the TX8201. The tones available are Alert, Evacuate, PreAnnounce and Bell. All four tones can be activated individually via rear panel contact closures. Tones can be disabled from the direct outputs via an internal dip switch (See the `Internal Adjustments' section of this manual for more information). A trim pot (R104) which is located on the board behind the left channel master output may be adjusted to vary the level of tone generator output. VCA Control An external pot (500K) can be connected to the TX8201 for remote control of the master level. The external pot is governed by the master level of the mixer allowing the installer to set the volume, then lock the mixer in a rack, leaving the user with just a master volume control that cannot go beyond the level set on the master (front panel) control. [. . . ] Never connect a "hot" (red) output to ground or to another "hot" (red) output!The power cord of equipment should be unplugged from the outlet when left unused for a long period of time. Service Information Equipment should be serviced by qualified service personnel when: A. The power supply cord or the plug has been damaged. [. . . ]
