Manual-3
PHONE Output jacks
These stereo ¼" TRS jacks accept standard
¼" TRS stereo headphone plugs.
POWER switch and LED
Your basic, straightforward power switch.
When the yellow LED is lit, the MH 4 is
ready to go.
Individual LEVEL controls
These control the volume for each set of
headphones as they are driven from the
INPUTS. It’s always a good idea to keep this
control turned down before plugging in a
pair of phones, then turn it up slowly.
INPUT jacks
These are automatic balanced/unbalanced
Inputs, which accept either a ¼" TRS (Tip-
Ring-Sleeve) plug for balanced operation, or
a ¼" TS (Tip-Sleeve) plug for unbalanced
operation. A balanced line is best when
connecting a cable over 10 feet in length.
You do nothing different when hooking up
balanced or unbalanced lines. The MH 4 is
one smart animal.
MH 4 CONNECTION
With the power switch in the
off
(out) position, plug the
power cord into the appropriate AC power source indicated
on the rear panel. Locate the power supply case away from
the MH 4 and other hum sensitive equipment.
Begin with all LEVEL controls counterclockwise at “0”.
Plug the outputs from a mono or stereo source into the
INPUTS.
See Sound System Interconnection on page 8 for more
information on proper cable wiring between devices.
