Front Panel Features
Input Level Controls
The 6 dual mic/line input controls are marked Ch 1 through Ch 8 and should be adjusted to provide the
required mix level for each individual channel. Start with the controls set to level 0 and turn the controls
slowly clockwise until the desired mix for each channel is obtained. Each of the inputs is also equipped
with an input sensitivity control which is located on the input PCB of the TX8000. Please refer to the
‘Other Internal Adjustments’ section of this manual for full details on this important feature.

Bass Control
Each channel has a recessed, screwdriver adjustable Bass control which forms part of a 2 band equalisation
system for each input. The Bass control allows the user to increase or decrease the amount of bass for that
particular input. The control allows for 12dB of cut or boost at 100Hz. If no bass cut or boost is required,
the control should be left in the centre (0) position.

Treble Control
Each channel has a recessed, screwdriver adjustable Treble control which forms part of a 2 band
equalisation system for each input. The Treble control allows the user to increase or decrease the amount of
treble for that particular input. The control allows for 9dB of cut or boost at 10kHz. Generally, a small
increase of the treble control makes a system sound ‘brighter’. If no treble cut or boost is required, the
control should be left in the centre (0) position.

Master Control
The master control sets the overall output level of the TX8000. It is used in conjunction with the input level
controls. When setting up levels, please ensure that proper gain structure practices are followed. In other
words, it is not advisable to run the input channels at 10 and the output level at 1. Instead, aim to keep all of
the input controls and the master control at around the same level.

Headphone Output Socket
A 1/4” (6.35mm) socket is provided for the connection of monitor headphones. The output level to the
headphones is a nominal 3.5 volts @ 600 ohms and is connected before the master output level control so
adjusting the output level control will not effect the headphone output level.

Power Switch & “On” LED
The black rocker switch on the right hand side of the front panel is used to switch the mixer on and off. The
‘up’ position is on. When the amplifier is connected to an appropriate AC power source and is switched on,
the blue “on” LED (located on the left side of the LED display) will illuminate.

LED Display VU Meter
The first LED indicates whether the unit is switched on. The remainder of the LED display is set in decibel
graduations from -21 dB to +3 dB and indicates the level at the output of the mixer. For normal operation
the LED’s should glow green and modulate with level variations from the input program. If the LED’s are
