1. Quick Start

Caution: Before switching on the power of the SbA750 always set the LEVEL control to its counterclockwise stop. A playing sound source could otherwise lead to extreme

output levels.

This Quick Start Manual outlines the set up and operation of a SbA750 used as add-on subwoofer together with a Powermixer (see configuration examples). The operation procedures are equivalent for other mixers.

1.Set up your Powermixer system as usual and connect a signal source to the power mixer (e.g. CD Player or microphone).

2.Place your SbA750 somewhere between your full-range cabinets.

3.Set the SbA750’s LEVEL control to its counterclockwise stop and connect the unit to a wall outlet using the supplied PowerCon mains cord.

4.Use a stereo phone plug cable to connect the Powermixer’s MONO OUT to the SbA750’s L/MONO INPUT.

5.Move the Mixer MONO OUT fader all the way down.

6.Be sure to switch on the Mixer first and then the SbA750.

Switching on the SbA750 last is recommended. Otherwise, unwanted power-on noise might occur. When switching off your equipment, please proceed in the opposite order, i.e. switch off the SbA750 first.

7.Set the SbA750’s LEVEL control to its center position (0dB) and start the playback of the desired signal audio source.

8.After adjusting the desired acoustic output level of the full-range cabinets using the Powermixer’s master fader, establish volume setting for the subwoofer using the MONO OUT fader.
