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”.

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.

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.
