5. CONNECTORS AND CABLES

The MX-406 mixer is fitted with four types of

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

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

(TRS) phone jack, and RCA jack. Certain 1/4" jack con-

nections may use an unbalanced 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 con-

struction. This type of cable should be used for all por-

table applications. Snake cables containing multiple

shielded pairs must be handled very carefully because the

leads tend to be fragile, and a broken conductor is diffi-

cult 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.
