Note: It is very important to use a top quality
RJ45 8/8 crimper tool. We strongly suggest
using a cat 5 / RJ45 electronic tester to verify
the wire conductors.
Introduction:
Thank you for your purchase of a Knoll GSZ67 12 channel
controller amplifier and congratulations on your choice. The GSZ67 features
six deluxe digital volume controlled stereo amplifiers with individual seven
source selection. This is Knoll's third generation of multi-channel, high-quality
power amplifiers. The GSZ67 is designed to meet the amplifier needs of
custom installed multi-zone systems where high quality sound is a specific
requirement.
Each of the six zones or rooms can select any of the seven inputs, with
individual volume control, bass, treble and balance. Extras such as an
external voltage trigger that can turn source equipment on and off, individual
zone infrared outputs, a fully balanced paging override, RS232 control, fully
buffered line level outputs and many more features give the GSZ67
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 GSZ67's. Infrared signals can be relayed from the keypads
to the source equipment.
The GSZ67 is normally controlled by MR164 LCD keypads with or without
Knoll remote controls or RS232 commands from whole house controllers. The
paging override is normally used for whole house announcements or doorbell
chimes.
Seven input source selection. Each of the six stereo amplifiers is provided
with seven input source selection. Selection, volume level, bass, treble and
balance is made on MR164 keypads, Knoll remote control (or a programmed
remote control) or via an external controller. Rooms can have different
source selections, volumes, etc.
Six internal 80 position stereo volume controls. The six zones can each
require a MR164 keypad, RB12 remote control or external controller via
RS232. 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 GSZ67 consists of a total of 12 power
amplifiers in one 3-1/2" high enclosure (two rack spaces). Each power
amplifier channel can deliver 50 watts RMS with peaks of 100 watts. Because
of its unique design the GSZ67 delivers exceptional value.
Automatic protection circuitry. Each GSZ67 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.
