SPEAKER OUTPUTS
Two parallel-wired jacks for min-
imum 4-ohm load, maximum
200-
watt output. Suggested speaker
load: two Model 3200 Loudspeak-
ers (8 ohms each, two in parallel
equal 4 ohms), or one or two other
high-power
&ohm speakers, or one
4-ohm speaker. Use
A50SC Acces-
sory Speaker Cable* to connect
speakers. If
only one 3200 soeaker
(or any other 8-ohm speaker) is
used, maximum power output will
be
120'watts.

SWITCHES
REVERB DEFEAT SWITCH
Quarter-inch phone jack for con-
nection of remote switch to dis-
able reverb.
PHANTOM POWER SW17
Turn On when powering
'C H
low-
pedance condenser microphones;
turn Off when not reauired.
SPEAKER OUTPUTS
Connecting too many speakers to
either or both jacks may result in
combined load below 4-ohm mini-
mum; operation may then cause
OVERLOAD LED to light and power
amp to shut down. Note that no
damage will result; Model 1200 is
protected against abnormal speaker
loads and short circuits. Again, if
two 1200's are connected together
via the Program Mix jacks, be sure
that maximum load on each power
amplifier does not fall below 4
ohms.

REVERB DEFEAT SWITCH
Without changing preset reverb
controls.
oermits temoorarv outout
minus reverb. Dc switching allows
use of unshielded cable. When
switch is closed (circuit shorted),
reverb signal is removed from pro-
gram mix by connecting tip to shell
(ground) of plug. A foot switch
works well.
PHANTOM POWER SWITCH
Supplies 24 Vdc to all low-impe-
dance microphone inputs. Bal-
anced low-impedance and unbal-
anced
high-im-pedance dynamic or
ribbon microphones can be used
in combination with condenser
microphones.
Do NOT use unbal-
anced low-impedance micro-
phones with
24
VDC switch On.

Provides up to 100 watts of ac power to accessory equipment (tape recorder,
graphic equalizer, effects device, phono preamp, etc.) Outlet is not swit-
ched, use switch on accessory; outlet is not intended for use with
high-
power equipment such as power amplifiers.
AC LINE CORD
Connect to ac power (1 20 Vac *1 Ox, 50160 Hz). Use only 16 AWG or larger
3-wire extension cords. Model 1200 may draw up to 5 amps from ac supply.
5A, 250V FUSE
Protects Model 1200 power supply against overload. Replace only with
