INTRODUCTION

The MX40 is a highly flexible but compact quad Gate suitable for a wide range of

professional applications including studio, live sound and audio installations. The

input and output connections are electronically balanced on XLR connectors and

low-distortion VCAs are used to maintain the highest possible signal quality.

Although optimised for +4dBu operation, the MX40 will work equally well with

systems operating at the -10dBu standard.

Any Noise Gate considerably improves the sound of percussive instruments by

producing fast leading edges to the signal and then shutting off after a pre-

determined time. The combination of this fast rising edge, and the silence which

follows the gated signal, creates a dramatic improvement to the original signal.

Drawmer pioneered the frequency conscious gating common to many noise gate

clones now available in audio processing equipment. The MX40 has a new spin on

this feature where both controls have been amalgamated into a single intuitive

control, of course with a Key Listen facility. This allows fast and simple setup of

frequency selective triggering where unwanted signals are prevented from triggering

the gate.

Input and Output audio connections are provided via balanced XLRs at a level of

+4dBu. This applies to both inputs and outputs. The wiring convention being:

Pin 1 Ground;

Pin 2 Hot(+);

and Pin 3 Cold(-).

For use with unbalanced systems, the Cold pin 3 must be grounded at both input and

output inside the XLR connectors. For connection to a patch bay, input sockets

should be wired 'fully normalised'.

The key input is an unbalanced ¼" (TRS) jack socket. For connection to a patch bay

this socket should be wired 'fully normalised' to prevent erratic triggering.

Interference: If the unit is to be used where it maybe exposed to high levels of

disturbance such as found close to a TV or radio transmitter, we advise that the unit

is operated in a balanced configuration. The screens of the signal cables should be

connected to the chassis connection on the XLR connector as opposed to connecting

to pin1. The MX40 conforms to the EMC standards.

Ground Loops: If ground loop problems are encountered, never disconnect the

mains earth, instead, try disconnecting the signal screen on one end of each of the

cables connecting the outputs of the MX40 to the patchbay. If such measures are

necessary, balanced operation is recommended.
