Rack Mounting
There are multiple solutions for rack-
mounting the MPA1. An optional Rack-
Mount Coupler allows the mounting of any
two Benchmark System1™ products in a
single rack space. A Blank Rack Panel can
be added when only one unit is being racked.
The System1™ Universal Rack Adapter is
a tray solution.
These rack-mount solutions are available
from Benchmark. Call us, visit our website
(http://www.BenchmarkMedia.com), or
contact your dealer to purchase these
accessories.
System1™ Universal Rack
Adapter
The Universal Rack Mount Adapter is a
tray that mounts up to two System1™
products in a single race space. The tray
accepts any combination of System1™
products (with or without rack-mount type
faceplates).
Blank Rack Panel
The Blank Rack Panel is a ½-wide 1-RU
black-anodized aluminum panel for covering
an unused slot in a System1™ Universal
Rack Adapter.
MPA1 Instruction Manual
Mounting Near Other
Equipment
CAUTION: STRAY MAGNETIC FIELDS
FROM ADJACENT EQUIPMENT MAY
CAUSE MAGNETICALLY INDUCED HUM IN
THE SENSITIVE HIGH-GAIN PREAMP
CIRCUITS.
The MPA1 is shielded in 3-dimensions with
mu-metal panels, which drastically reduces
susceptibility to stray magnetic fields. The
MPA1 may be mounted directly above or
below any other equipment, but we cannot
guarantee that the MPA1 will be impervious to
interference from all equipment mounted too
close to the MPA1. It is recommended that
the user apply caution by using the following
procedure when mounting near other
equipment:
TIP: TO CHECK FOR MAGNETIC
INTERFERENCE FROM ADJACENT
EQUIPMENT:
1. Disconnect all microphones
2. Back-terminate microphone inputs
3. Set all preamp gain controls at maximum
4. Listen to headphone output
5. Unplug adjacent equipment to determine
if there is any magnetic interference
TIP: IN MANY CASES, POWER SWITCHES
DO NOT TURN OFF ALL OF THE
MAGNETIC COMPONENTS IN AN
ELECTRONIC DEVICE. THEREFORE, WHEN
PERFORMING MAGNETIC INTERFERENCE
TESTS, IT IS IMPORTANT TO UNPLUG
THE ADJACENT EQUIPMENT TO INSURE
THAT THESE DEVICES ARE TRULY OFF.
