Overview  
The VM-1110xl is a high performance balanced audio DA (distribution  
amplifier) using XLR connectors. It can be configured as a mono (1:10 or  
2x1:5) DA or as a stereo (1:5) DA.  
The VM-1110xl features:  
ñ
ñ
Front panel output level trimmer controls  
Active Bi-FET amplifying circuitry that ensures hum-free, full-  
bandwidth operation  
ñ
A high-power discrete buffering system providing excellent  
performance  
To achieve the best performance:  
ñ
Use only good quality connection cables1 to avoid interference,  
deterioration in signal quality due to poor matching, and elevated  
noise levels (often associated with low quality cables).  
ñ
Avoid interference from neighboring electrical appliances that  
may adversely influence signal quality and position your Kramer  
VM-1110xl away from moisture, excessive sunlight and dust

Installing the VM-1110xl in a Rack

Installing the VM-1110xl in a Rack  
This section describes how to install the VM-1110xl in a rack.  
Before Installing in a rack  
How to Rack Mount  
To rack-mount a machine:  
Before installing in a rack, be sure that the environment is  
within the recommended range:  
Operating temperature range +5è to +45è C (41è to 113è F)  
1. Attach both ear brackets to the  
machine. To do so, remove the  
screws from each side of the  
machine (3 on each side), and  
replace those screws through the  
ear brackets.  
Operating humidity range  
Storage temperature range  
Storage humidity range  
10 to 90% RHL, non-condensing  
-20è to +70è C (-4è to 158è F)  
5 to 95% RHL, non-condensing  
!
CAUTION!!  
When installing on a 19" rack, avoid hazards by taking  
care that:  
1. It is located within the recommended environmental  
conditions, as the operating ambient temperature of a  
closed or multi unit rack assembly may exceed the  
room ambient temperature.  
2. Once rack mounted, enough air will still flow around  
the machine.  
2. Place the ears of the machine  
against the rack rails, and insert the  
proper screws (not provided)  
through each of the four holes in the  
rack ears.  
3. The machine is placed straight in the correct  
horizontal position.  
Note that:  
4. You do not overload the circuit(s). When connecting  
the machine to the supply circuit, overloading the  
circuits might have a detrimental effect on overcurrent  
protection and supply wiring. Refer to the appropriate  
nameplate ratings for information. For example, for  
fuse replacement, see the value printed on the  
product label.  
5. The machine is earthed (grounded) in a reliable way  
and is connected only to an electricity socket with  
grounding. Pay particular attention to situations where  
electricity is supplied indirectly (when the power cord  
is not plugged directly into the socket in the wall), for  
example, when using an extension cable or a power  
strip, and that you use only the power cord that is  
supplied with the machine.

In some models, the front panel  
may feature built-in rack ears  
Detachable rack ears can be  
removed for desktop use  
Always mount the machine in the  
rack before you attach any cables  
or connect the machine to the  
power  
ñ
If you are using a Kramer rack  
adapter kit (for a machine that is not  
19"), see the Rack Adapters user  
manual for installation instructions
