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.
