TXM16 and TXM20 Input and Output Connections
CHANNEL 1 – 8 (12) MONO MIC/LINE INPUTS
The TXM mixers offer plenty of mono mic/line and stereo
line input channels, sixteen on the TXM16 and twenty on
the TXM20's, for connecting a variety of signal sources
from microphones to line level devices such as synthesiz-
ers, drum machines and direct boxes.
The mono mic/line inputs each have a LINE level, Hi-
Z (High Impedance) input , a MIC level, Low-Z (Low
Impedance) input; and an Insert connector for effects.
Both LINE and MIC inputs are balanced, with MIC inputs
compatible with microphones of output impedance
50-600 Ohms and LINE inputs compatible with line level
devices of 600 Ohms. Following is a description of the
Mic/Line input connectors:
A - MIC - Microphone Input
Use these inputs to connect Low Impedance micro-
phones and low-level signals from direct boxes. The MIC
inputs have a nominal operating level of –50dBV through
-20dBV. The MIC inputs also feature +48V phantom
power, allowing you to use condenser microphones. The
Phantom Power is switched on/off simultaneously for
channels 1 through 8(12). XLR connector pin-out - Pin 1:
Ground, Pin 2: Hot (+), Pin 3: Cold (-)
B – LINE - Line Level Input
Use these inputs to connect high impedance micro-
phones, synthesizers and drum machines. The LINE
inputs have a nominal operating level of -40dBV through
- 10dBV. TRS phone jack connector pin-out - Sleeve:
Ground, Tip: Hot (+), Ring: Cold (-)
NOTE: It is not possible to simultaneously use both the
LINE and MIC inputs on the same channel. For each
channel, use only one of the inputs as appropriate for
the input source.
C – INSERT - Send and Return jack
The TXM16 and TXM20 have a 1/4-inch, TRS (TIP/RING/
SLEEVE) Insert jack for connecting outboard effects pro-
cessors directly on the channel input. The signal is sent on
the tip (the Send) and returns on the ring (the Return) of
the connector.
Stereo Input Channels - 1/4-inch and RCA
Each of the TXM mixers has two sets of full-featured
stereo input channels, Channels 9/10 and 11/12 on the
TXM16 and Channels 13/14 and 15/16 on the TXM20. Use
these for connecting stereo signals like those from CD or
MP3 players, electronic keyboards, drum machines and
other line level signals. These inputs have both 1/4-inch
and RCA connectors for connecting your gear. Following
is a desciption of the Mic/Line input connectors:
D - Stereo Inputs - RCA jacks
The TXM stereo channel 's RCA connectors accept signals
from stereo line devices. The RCA line level inputs have a
nominal operating level of -40dBV through - 10dBV.
E - Stereo Inputs - 1/4-inch jacks
The TXM16 and TXM20 have two pairs of 1/4-inch jacks
for connecting stereo line level sources. For stereo inputs
use the LINE L to connect the left channel and the LINE R
to connect the right channel. Use these inputs to connect
high impedance microphones, synthesizers and drum
machines. The LINE inputs have a nominal operating level
of -40dBV through - 10dBV. TRS phone jack connector
pin-out - Sleeve: Ground, Tip: Hot (+), Ring: Cold (-)
Stereo Input Channels - 1/4-inch
Each of the TXM mixers has two sets of basic stereo line
level input channels, Channels 13/14 and 15/16 on the
TXM16 and Channels 17/18 and 19/20 on the TXM20, for
connecting stereo signals like those from CD or MP3 play-
ers, electronic keyboards, drum machines and other line
level signals.
F - Stereo Inputs - 1/4-inch jacks
The TXM16 and TXM20 have two pairs of 1/4-inch jacks
for connecting stereo line level sources. For stereo inputs,
use the LINE L to connect the left channel and the LINE R
to connect the right channel. If you are using the inputs
for a mono line input, use the LINE L input, (channels 13
or 15 on the TXM16 and channels 17 or 19 on the TXM20),
only so that the signal feeds both the right and left Main
mix bus. Use these inputs to connect high impedance
microphones, synthesizers and drum machines. The LINE
inputs have a nominal operating level of -40dBV through
14
