OPERATION

To connect various devices to the MX44 Pro, you'll need
the proper cables.

- Connecting most CD, Cassete, and Video units will
require a stereo RCA to stereo or 1/8" (3.5mm) cable. A
stereo plug consists of tip, ring and sleeve.

- Most stereo instruments have individual Right and Left
outputs. Therefore, you'll need an "Insert" type cable. This
cable has two 1/4" or 1/8" Tip-Sleeve jacks on one end to
connect to the stereo instrument, and a single Tip-Ring­Sleeve stereo 1/8" jack on the other end to connect to
the MX44. For assistance on cable selection, contact your
local professional audio dealer.

- Some devices have stereo 1/4" outputs that can be con­nected to the 1/8" inputs of the MX44. These devices will
require a 1/4" TRS stereo to RCA or 1/8" TRS stereo cable.

- While the MX44 is not a headphone amplier, the out­puts have sucient level to drive a pair of headphones or
earphones for limited monitoring.

- NOTE: PLUGGING A TIP-SLEEVE MONO PLUG INTO THE
MX44 WILL NOT DAMAGE THE UNIT. HOWEVER, THE
SIGNAL WILL BE HEARD ON ONLY THE LEFT SIDE. DO NOT
PLUG A MONO JACK INTO THE OUTPUT - THIS WILL DAM­AGE THE UNIT.
TO SEND A MONO SIGNAL TO THE MX44, USE A TRS JACK
WITH THE TIP AND RING CONNECTED TOGETHER.
