QUICK START

1. Start with the following settings on the front of the

SRM150:

• MAIN LEVEL [6] control down.

• PHANTOM POWER [5] switch out (unless you are

using condenser microphones).

• INSTRUMENT [4] switch out (unless you have an

electric guitar connected to channel 1).

• Channels 1-3 gain [3] controls down.

• EQ [7] controls centered.

And on the rear panel:

• Turn the POWER [8] switch off (down).

• MIC/LINE [12] switch out.

WARNING: Turn the MAIN LEVEL

[6]control down (counterclockwise)

before every use. If not, you could be

in for a startling surprise, especially

if the last time you used it was with

a microphone and now you want to

connect a line-level source.

2. Connect the output from your signal source (mixing

console, microphone, preamp, or other mic- or line-

level source) directly to the MIC/LINE [1] combo

connector on the front of the SRM150. It accepts

balanced line-level signals from mixers, preampliﬁ-

ers, CD players, tape decks, etc., and accepts direct

connections from microphones. Channel 3 has ste

reo RCA jacks [2] speciﬁcally for a stereo line-level

input from a tape deck or CD player.

3. Connect the supplied AC power cord to the AC

power receptacle [10] on the back of the SRM150.

Plug the other end into an AC outlet properly con-

ﬁgured with the correct voltage for your particular

model. (The SRM150 has a universal power supply

that accepts an AC mains voltage ranging from 100V

to 240 V.)

4. Turn on your signal source. Make sure its Master

Volume control (if it has one) is turned all the way

down.

5. Turn on the SRM150 POWER [8] switch.

6. Start the signal source, whether it be speaking into

a microphone, playing a guitar, or starting a CD

player. Adjust any volume controls on the signal

source for normal operation.

7. Turn up the MAIN LEVEL [6] control about halfway

(12 o’clock).

8. Slowly turn up the gain [3] controls for the input

channels until the desired volume is reached.

9. If it gets really loud, really fast, try turning down

the MAIN LEVEL control (or the input source

volume control, if it has one).

If it doesn’t get very loud, even with the input chan

nel gain control all the way up, try turning up the

MAIN LEVEL control (or the input source volume

control, if it has one).

10. If there is no sound, always turn down the SRM150

MAIN LEVEL control before investigating. There

may be a mixer or preampliﬁer mute or tape switch

engaged, or a mic switch off.
