Connect to speaker systems such as the Shure 701 or 709.
Suggested speaker loads for the console include:
2-Shure Model 701 or 709 PRO MASTERTM 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
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 temper-
ature (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 head-
phones) for tape recording.
