OPERATION
To connect various devices to the MX44s, you'll need the proper cables.
- Connecting most CD, Cassete, and Video units will require a stereo RCA to
stereo 1/4" or 1/8" (3.5mm) cable. A stereo plug consists of tip, ring and sleeve
connections - shown in Fig. 1.
- Most stereo instruments have individual Right and Left outputs. Therefore, you'll
need an "Insert" type cable. This cable has two 1/4' TIp-Sleeve jacks on one end
to connect to the stereo instrument, and a Tip-Ring-Sleeve stereo jack on the
other end to connect to the MX44s. For assistance on cable selection, contact
your local professional audio dealer.
- Some devices have stereo 1/4" outputs identical to the inputs of the MX44s.
These devices will require a 1/4" TRS stereo to 1/4" or 1/8" TRS stereo cable.
NOTE: PLUGGING A TIP-SLEEVE MONO PLUG INTO THE MX44s WILL NOT
DAMAGE THE UNIT. HOWEVER, THE SIGNAL WILL BE HEARD ON ONLY
THE LEFT SIDE. DO NOT PLUG A MONO JACK INTO EITHER OUTPUT
- THIS WILL DAMAGE THE UNIT.
TO SEND A MONO SIGNAL TO THE MX44s, USE A TRS JACK WITH THE TIP
AND RING CONNECTED TOGETHER.
While the MX44s is not a headphone amplifier, the outputs have sufficient level
drive a pair of headphones or earphones for limited monitoring.
