XLR Input and Output

The EZ-MCP1 is an in-line microphone compressor that produces consistent audio levels despite wide variations (up to 30 dB)
from the microphone. It is installed between a dynamic or condenser microphone and a mic-level mixer or amplifier input.
The only setup required is a front-panel level trimmer that is adjusted during normal speech until the compression LED just
begins to flash. A rear-panel output level trimmer is provided although it is typically left in the normal default position. Phantom
voltage (24 V) is automatically switched on when the EZ-MCP1 output is connected to a mic jack that provides phantom voltage.
The EZ-MCP1 improves sound quality and intelligibility by producing consistent audio levels and controlling overloads that
produce distortion and clipping. It is used for recording, paging and public address in houses of worship, restaurants, clubs,
meeting rooms, educational facilities, conference rooms and commercial sound systems.

MIC INPUT

Plug a microphone into the jack. The microphone may be
either a standard dynamic or a condenser microphone.

LEVEL ADJUSTMENT

Speak into the microphone at the lowest normal
speech level. Adjust the LEVEL control until the
COMPRESSION LED just begins to flash.

PHANTOM

The PHANTOM LED glows
when 24 V phantom is
being provided to the
microphone connected to
the MIC INPUT. (Phantom
is automatically turned on
when the MIC OUTPUT
is connected to other
equipment that provides
phantom voltage.

24 VDC POWER INPUT

Insert plug from power
supply. Rotate 1/4 turn
clockwise to lock.

MIC OUTPUT

Connect to the microphone input
of other equipment, typically a
mixer or amplifier.

POWER INDICATOR

Glows blue when the
product is connected to a
valid power source.

OUTPUT LEVEL

Set to the NORMAL position. Increase or decrease the
level only if necessary.

Maximum overload protection is achieved if the OUTPUT
LEVEL control is set to NORMAL and the proper system
mic level is adjusted on the system mixer or amplifier. The
OUTPUT LEVEL adjustment is normally used if access to
the system mixer or amplifier is unavailable. Note: The
mic input of the system mixer or amplifier may overload if
the OUTPUT LEVEL is turned up too high.
