TX8000
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 bal-
anced 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 set-up for each channel via an internal trim control.

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 con-
trols. An internal trim control is also provided for every channel.
Metering
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 pro-
vides two levels of priority. Channel 1 is the master mute channel and overrides channels 2-8,
whereas channel 2 will mute channels 3-8.
