Electro-Voice ® SbA750 User Manual 3
Input L/Mono, Input R
Electronically balanced inputs for the connection of high-
level signal sources such as mixers, signal
processors, etc. Establishing the connection is possible via
phone or XLR-type jacks. Balanced connection
is recommended to prevent noise or HF-interference.
Caution: Before connecting or disconnecting any plugs,
make sure to set the level control to its counterclockwise
stop, which prevents the system, the audience and yourself
from being stressed by nasty contact noise.
The input section of the SbA750 also allows mono sub
operation. The stereo signal is fed to the L and R inputs
and the low-frequency range signals of both channels are
summed prior to being processed in the power amplifier
section. All other applications use only the (L)/Mono input.
Please also refer to the chapter “SETUP EXAMPLES”.
2. Controls
Level
This control sets the output volume of the SbA750 in a
range between -∞dB and +10dB. The internal power
amplifier provides a nominal input sensitivity of +6dBu.
Parallel Outputs L/R
Parallel connected to the main inputs these sockets are
used for “carrying through” the input signals.
Mid-High Outputs L/R
The input signal is split via the integrated electronic cross-
over (PowerMax, 100Hz). Low-frequency signals
are routed to the internal power amplifier of the SbA750
while high-frequency signals are present at the Mid-High
outputs for further distribution to external power amps or
active mid-high range cabinets.
