Overview

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

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
