Introduction:
Thank you for your purchase of a Knoll GSZ44 8 channel
controller amplifier and congratulations on your choice. The GSZ44 features
four deluxe digital volume controlled stereo amplifiers with individual four
source selection. This is Knoll's fourth generation of multi-channel, high-
quality power amplifiers. The GSZ44 is designed to meet the amplifier needs
of custom installed multi-zone systems where high quality sound is a specific
requirement.
Each of the four zones or rooms can select any of the four inputs, with
individual volume control, bass and treble. Extras such as an external voltage
trigger that can turn source equipment on and off, individual zone infrared
outputs and many more features give the GSZ44 exceptional value when
installed in homes and large complex systems. Except for the power button
all controls are rear mounted. A data port is provided for ganging multiple
GSZ44's. Infrared signals can be relayed from the keypads to the source
equipment.
The GSZ44 is controlled by MR40 keypads.
Four input source selection. Each of the four stereo amplifiers is provided
with four input source selection. Selection, volume level, bass and treble is
made on MR40 keypads or a Knoll remote control (or a programmed remote
control). Rooms can have different source selections, volumes, etc.
Four internal 80 position stereo volume controls. The four zones each
require a MR40 keypad. The Knoll RB8 remote control (or a programmed
remote control) in conjunction with the MR40 keypad can control each zone.
The keypads are typically mounted in the room with the speakers and they
control amplifier power on/off, volume up/down and mute as well as source
selection.
Cost and size efficiency. The GSZ44 consists of a total of 8 power
amplifiers in one 3-1/2" high enclosure (two rack spaces). Each power
amplifier channel can deliver 30 watts RMS with peaks of 60 watts. Because
of its unique design the GSZ44 delivers exceptional value.
Automatic protection circuitry. Each GSZ44 amplifier channel is
individually and fully protected against low impedance, overheating,
overloading, over voltage and under voltage. The protection circuitry
automatically restores the amplifier channel as soon as its parameter returns
to the safe operating area.
Individual bass and treble adjustment. Each channel features adjustments
so installers can preset the room for speaker differences and listener
preferences.
External trigger. The GSZ44 can turn on and off source components with
its 12vdc trigger output.
Infrared controller ports. Each zone or room has its own infrared output
jack. An all zone jack is also provided.
Zone 1 has line level outputs so more powerful power amplifiers can be
connected to this output. The line level output is controlled as to volume,
bass, treble and source selection.
