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
