Before turning the amplifier on please read the following sections to make sure that the unit is set up
properly for your specific application.

The gain of the iP 1150Q is fixed to 32 dB
RKNKO= pÉåëáíáîáíó=
Sensitivity is defined as how many volts (rms) or dBu (referred to 0.775Vrms) are required to get full
output power. As the output power varies with the load impedance, usually 4 ohms is the reference.

The Link switches located on rear panel (switches between the four XLR input connectors) are for
changing the operation mode of the amplifier. (See below, section 5.3).
RKP= léÉê~нбзе=гзЗЙл=
RKPKN= píÉêÉç=гзЗЙ=
In this mode, both channels operate independently of
each other. This is used for all 2 or 4-channel modes,
such as stereo and bi-amping. Set the switches in
depressed -OUT position for the stereo mode. The
level attenuators on the front panel will control the
respective channels levels.
Never connect either output terminal to ground
or in parallel. The recommended minimum nominal
impedance, for quad or tandem stereo operation, is 2
ohms per channel.
