Samson TXM20 User Manual

5. Make sure the channel faders are all down, then set the

MAIN level fader control to the “0” position.

6. Before you turn up a channel, you want to make sure

you set a good level, with no distortion, on the channel

input GAIN. While speaking into the mic (or playing the

instrument), adjust the channel GAIN control so that the

“PEAK” LED of the channel lights occasionally, then back

it down slightly.

7. Once you have set the GAIN control, slowly adjust the

channel LEVEL fader control until the desired level is

reached.

8. If you wish to adjust the tone of each channel, adjust

the equalizer controls as desired. You may have to re-

adjust the channel volume.

9. Use the MAIN STEREO GRAPHIC EQ section graphic

equalizer and MASTER control to adjust the overall vol-

ume and tone. You can increase the overall level of your

system by cutting certain frequencies that cause feed-

back.

Operating the TXM16 and TXM20

BASIC OPERATION
The following section explains the basic operation of the

TXM16 and TXM20.

CONNECTING MICROPHONES AND

INSTRUMENTS

1. Before connecting mics or instruments, make sure that

the power of all your system's components, including the

TXM mixer, is turned off. Also, make sure that the vol-

ume and gain controls of each channel of the TXM16 or

TXM20 and the MAIN, MONO, AUX1 and AUX2 level fad-

ers are turned all the way down.
2. Next, make the connection to your speakers using

heavy gauge, un-shielded speaker cable.

3. Connect the cables to your microphones and instru-

ments, and insert the other end of the cable firmly into

the appropriate input on the TXM16 or TXM20.
4. Switch on the power of any peripheral devices, and

then power up the TXM16 and TXM20.
NOTE: Since the TXM16 and TXM20 contain two internal

power amplifiers, it is important to remember the Golden

Rule of audio … "LAST ON, FIRST OFF". Translated,

this means that when powering up your PA system, you

should always turn your power amplifiers on LAST, and

when power your system down, turn your power amps

off FIRST.
This helps avoid any loud pops caused by in-rush current

at power up or power down, which can sometimes dam-

age loudspeakers.
