Operating Manual -MX-406 Stereo Microphone/Line Mixer

5. CONNECTORS AND CABLES

The MX-406 mixer is fitted with five types of au-

dio connectors: 3-pin XLR type male (mono output), 3-

pin XLR type female (mic inputs), 1/4" tip-ring-sleeve

(TRS) phone jack, 3.5mm jack (stereo line in), and RCA

jack. Certain 1/4" jack connections may use an unbal-

anced mono plug, which is also shown.

Two-conductor (twisted pair) shielded cable is

best for all XLR type connections. Belden No. 8412 or its

equivalent is an excellent cable due to its heavy construc-

tion. This type of cable should be used for all portable

applications. Snake cables containing multiple shielded

pairs must be handled very carefully because the leads

tend to be fragile, and a broken conductor is difficult to

repair.

If low level and high level lines are run parallel

for long distances, crosstalk may occur. In fact, the

crosstalk (signal leakage between cables) can cause an

electronic feedback loop, oscillation, and possibly dam-

age to the equipment. To minimize crosstalk, physically

separate low level (microphone) cables from speaker

cables by the greatest feasible distance. At any point

where cables meet, run low level cables perpendicular to

high level or speaker cables. If low and high level or

speaker cables must be run parallel and in close proxim-

ity to one another, they should be bundled separately. In

a permanent installation, avoid running speaker cables and

mic cable through the same conduit pipe.

6.1 Microphone Input

The MX-406 microphone input is an active bal-

anced type with a nominal impedance of 1200 ohms. Its

noise performance is best with a 200 ohm microphone.

The Mic input connector is a standard 3-pin XLR female

with the shield on pin 1, the (+) in-phase connection on

pin 2, and the (-) out-of-phase connection on pin 3.
