User manual AUSTRALIAN MONITOR TX8201 WITH VCA

[. . . ] 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. Start with the output controls set at approximately the Level 5 position and adjust clockwise for more output level or counter-clockwise for less output level. Pan Control Each input channel has a recessed (screwdriver adjustable) pan control. [. . . ] The output is an active balanced isolated output for connection to a power amplifier. Note: If an unbalanced output is required, use a 600 Ohm matching transformer or use only Pin 2 and Earth. Do not short any of the active outputs to earth. Tape Output Two RCA output connectors are included on the rear panel. The tape output provides a maximum of 500mV into 10K ohms making it ideal for connection to most standard tape recorders. This output is sourced before the master gain control and as such the tape output level is not influenced by the operation of the master gain control. Dual RCA Stereo Line Inputs (Ch 7 & 8) The top connectors are for the Left channel auxiliary inputs while the bottom connectors are for the Right channel auxiliary inputs. 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, -). 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. 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. 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. [. . . ] Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such as a battery, mains source, or power supply, regardless of whether the amplifier or console is turned on or off. Do not run the output of any amplifier channel back into another channel's input. Do not parallel- or series-connect an amplifier output with any other amplifier output. Australian Monitor Inc is not responsible for damage to loudspeakers for any reason. Never connect a "hot" (red) output to ground or to another "hot" (red) output! [. . . ]
