CONNECTIONS

Rear Panel Connections

Inputs

MIC 2 and MIC 3

Each of these two female XLR connectors provides a balanced mono input for a

microphone, which typically outputs lower signal levels. An additional 26 dB of gain is

provided to boost the mic signal to near line level. The mono signal of each mic input is

fed to both left and right stereo channels and mixed with the line-level input signals

from the RCA jacks of the same channel. This combined signal may be assigned to

either Zone 1 or Zone2.

+48V phantom power is available to operate those microphones that contain active

electronic circuitry (such as condenser mics) and may be applied by setting the

corresponding PHANTOM POWER switch in the down (ON) position. The switches are

located towards the right of the rear panel. See page 8 (Rear Panel Controls) for

more information. Note: Do not apply phantom power unless the microphone is

designed to use it.

LINE INPUT 1 through 6 (LEFT and RIGHT)

Each of these six stereo pairs of RCA phono jacks provide unbalanced inputs for line

level signals. The top row of jacks is for left channel connections and the bottom row is

for right channel connections.

ZONE 1 and 2 BUS INPUTS

These stereo (TRS) phone jacks provide a direct buffered input connection to the

MX624's internal zone buses. They can be used to chain multiple MX624's together,

using special cables with dual 1/4-inch mono (TS) phone plugs connected to a single

1/4-inch stereo (TRS) phone plug (tip is left and ring is right). Be sure the connections

use shielded cable. Then simply connect the ZONE 1 or 2 OUT (or both) jacks of one

MX624 to the ZONE 1 or 2 BUS INPUT (or both) jacks of another MX624.
