Samson TXM20 User Manual

NOTE: The signal feeding EFX1 and EFX2 is sent after the 

channel Fader (14), so the channel Fader has an effect on 

that level, meaning the Aux level tracks up and down with 

the channel Fader. This means that the amount of signal 

that is sent to the EFFECTS bus will be affected not only 

by the setting of the EFX knob control, but it will also be 

affected by the setting of the channel Fader volume con-
trol.

The TXM16 and TXM20’s PAN control is used to place or 

position the mono signal into the stereo main Left and 

Right MIX bus. You can create a stereo image by panning 

some input signals to the left and others to the right. The 

TXM16 and TXM20’s PAN control is a Power-Pan circuit, 

which includes a 3dB dip in the center position.  This is 

desirable since there’s a 3dB increase in gain when the 

mono input signal is heard in both the Left and Right MIX 
bus. 

The Mono Input channels feature a large, backlit 

MUTE switch allowing you to easily turn that chan-

nel on or off. When MUTE switch is illuminated, the 

channel is off, conversely, when the backlight is off, 

the channel is on. 

The Mono Input channel’s PFL, or Pre Fader Listen switch 

allows you to listen, or “solo” a channel or group of chan-

nels in the headphones. When the PFL switch is pressed 

down, the channel is assigned to the solo bus and can 

be heard in any optional headphones plugged in to the 

PHONES connector located in the front panel jack field. 

Since the signal is sent pre fader, you can hear the signal 

regardless of the position of the channel volume Fader. 

This allows you to listen to a channel by itself: (let's say) to 

see if an artist is out of tune, or to cue up a channel with-

out having to play it through the main PA speakers. 

The TXM16 and TXM20’s MIC/LINE pre-amp also includes a 

PEAK LED which when illuminated, indicates that the sig-

nal is peaking or overloading.  To reduce distortion, lower 

the GAIN control to keep this LED from staying on. 

The VOLUME Fader control adjusts the level of each mono 

input channel.
