8 Channel Mic/Line Mixer

Description

The TX8000 is a high specification, single rack space, 8 channel mixer suitable for desk or rack
mounting. The mixer is designed to operate from both AC mains power as well as 24 volts DC.

Inputs

The TX8000 has six dual mic/line inputs and two mic only inputs. The mic inputs are active balanced
and feature 3 pin XLR female sockets. The line inputs feature dual female RCA sockets. Each chan­nel includes front panel, screwdriver adjustable treble and bass controls. Individual gain can be set­up for each channel via an internal trim control.

Outputs

The TX8000 features a balanced line output via a 3 pin male XLR socket. A mono tape output is
also available via dual female RCA sockets. A 1/4” headphone socket is included on the front panel.

Controls

Front panel controls include the master output level plus individual channel level controls. Each
channel also includes front panel recessed screwdriver adjustable treble and bass control controls.
An internal trim control is also provided for every channel.

VCA Control

The master volume can be controlled remotely. External VCA control would normally be via a pot
connected to a two wire rear panel barrier strip.

A 7 segment LED meter is provided for the master output. A power “on” LED is also included.

Muting

Muting is available via the optional VOX operated plug-in TX3010 or TX3014 precedence cards.
The TX3010 provides priority from channel 1 over all other channels. The TX3014 provides two lev­els of priority. Channel 1 is the master mute channel and overrides channels 2-8, whereas channel
2 will mute channels 3-8.
