Power and Speaker Connections
Power ON-OH Switch
Applies ac power to power supply (does not switch ac outlet)
Unswitchd AC Grounded Outlet
Provides up to 100 watts of ac power to accessory equipment
(mixer, tape recorder, lamp, etc.). The outlet is not fused and not
switched; use the power switch on the accessory equipment.
The outlet is not intended for use with high-power equipment
such as power amplifiers.
AC Line Cord
Connect to ac power (120 Vac ? lo%, 50160 Hz). Use only 16
AWG (or larger), three-wire extension cords. Console may draw
up to
9 amperes (1 100 watts) from ac supply circuit. May be
operated from other voltages (see Service Manual).
1011,250V Fuse
Protects console power supply against overload. (Replace only
with identical size and type:
10A, 250V, type 3AB or ABC.)
Speaker Outputs Jock (4)
Connect to speaker systems such as the Shure 701. Two parallel
jacks are for PA (power amplifier) A and two are for PA
B. Do not
connect A and B SPEAKER OUTPUT jacks together as distortion
and possible damage may result; for monophonic output, see
SETUPS section. Remove and replace speaker jack cover when
connecting speakers. Suggested speaker loads for each
amplifier of the console include:
2-Shure Model 701 PRO MASTER'" Speaker Systems (8
ohms each), or
4-Shure Model 702 Stage Monitor Speaker Systems (16
ohms each), or
2-Shure Model 703 PRO MASTER'" Stage Monitors
(8
ohms each), or
4-Shure Model
SR102 or SR103 Speaker Columns (16
ohms each), or
2-Shure Model
SR112 or SR116 Compact Speaker
Systems (8 ohms each).
Connecting too many speakers to either or both output jacks may
result in a combined load below the 4-ohm minimum. Operation
with such a load may cause an excessively high internal
temperature (TEMP WARNING LED turns on), or the PA (power
amplifier) OVERLOAD LED may turn on at lower than normal
levels (before
the+6 dB LED). Note that no damage will result;
the console is protected against speaker overloads and shorts.
Also, the console may be operated without speakers (with
headphones) for tape recording.
