Unpacking: The carton and packing materials used in shipping your new amplifier
were specially designed to protect it from the shock and vibration of shipping. We
suggest that you save the carton and packing materials to use if you move, or if the
unit ever needs to be shipped back to us for any reason. Should you discover that
your amplifier has been damaged during shipping, please contact your dealer or
Knoll immediately and request the name of the carrier so a written claim can be
made.
The right to a claim against a public carrier can be forfeited if the
carrier is not notified immediately in writing and if the shipping
carton and packing materials are not available for inspection by the
carrier. Save all packing materials until the claim is settled.
GRS44 placement
During normal home operation the amplifier will become warm. However, there are
instances during high-level playback into low impedance speakers when the amplifier
will become much warmer than normal. To ensure the amplifier’s trouble-free
operation, it is necessary to provide adequate ventilation. Your amplifier should be
kept away from external sources of heat such as radiators and hot-air ducts. The
amplifier should never be placed with other heat-producing components in a cabinet
or enclosure lacking free airflow. Do not stack other components on top of your
amplifier.
Connecting your amplifier
When making connections between any source components and the amplifier, or
when making connections to any speaker, be certain that both the input devices and
the amplifier are turned off. Unplug all equipment before making any connections so
that there will be no unwanted signal transients that can damage equipment or
speakers.
Input connections
Connecting the GRS44 to your source equipment is straightforward. Using the high-
quality RCA audio interconnect cables, match the output channel designations on the
rear of your source equipment to the input jacks on the rear panel of your amplifier
that have the same channel name.
When making connections with RCA type plugs on interconnect cables, make certain
to gently, but firmly, insert the plug into the jack. Loose connections can cause
intermittent sound and may damage your speakers. Some quality RCA plugs may be
very tight, and it is important to secure a proper connection between the
interconnection cable and the input jack.
We suggest starting with the input gains on the rear of the GRS44 set to mid
position. After it is installed and being tested these gains are use to set the different
source input levels so they are roughly the same. Some sources such as DVD players
have a very high output and may cause the GRS44 to send clipped signals to the
speakers even at low volume levels, so we suggest lowering the input gains of that
input in this case to stop the clipping
