TXM POWERED MIXERS
GENERAL DESCRIPTION
The TXM20 is a twenty channel, powered mixer in an
ergonomically correct, attractively appointed, tabletop
enclosure. The TXM20 features a massive 1000-watt power
amplifier, which is capable of running in 2 x 500-watt stereo,
500-watt Main plus 500-watt monitor, or 1000-watt bridge
mono operating modes. To set the overall tonal response
of your mix, the TXM20 features a 9-band Stereo Graphic
Equalizer for the Main Left and Right outputs, plus a separate
9-band Graphic Equalizer for your monitor mix. Connecting
all your microphones and instruments is simple, with twelve
mic/line inputs plus four additional stereo channels. There are
also dedicated stereo effects returns for the onboard digital
effects. And the effects! You can add one of the TXM20’s
100 dazzling digital studio quality effects, which include
Delays, Chorus, Flanging, and of course, lush Reverbs to your
vocals or instruments using the onboard 24-bit Multi-Effects
Processor. It’s easy to dial up your favorite effects preset with
the large seven-segment LED display. Need more effects?
The TXM20 employs two onboard 24-bit Multi-Effects
Processors. Plus, the TXM20 has extensive auxiliary busses
allowing you to have complex combinations of effects on all
the channels, or two different effects on different groups of
channels. The auxiliary buses are also extremely flexible when
it comes to monitor mixes. The TXM20 will give you clean,
clear sound reproduction thanks to the high quality, low noise
microphone preamps, super clean, low impedance mix bus,
two on-board 9-band graphic equalizers and the high output/
low distortion power amplifier. The units are easy to transport
with their compact size and oversized, sure-grip handle.
The super-tough steel construction ensures reliable, high
quality sound from venue-to-venue and performance-to-
performance day in, and night out. Optimized for live sound
reinforcement and commercial installations, the TXM20 is an
ideal mixer and power amp solution that offer plenty of inputs,
sweet sounding effects and big sound in a compact package.
FEATURES
> The TXM20 is a twenty channel powered mixer in an
ergonomically correct, table-top enclosure providing easy
to see and easy to operate front panel controls. In addition,
the TXM20 can be rack mounted using the included
eleven-space rack mount kit.
