Installation requirements

The Martin Audio Engineer 818 is designed for 19” rack-mount use.

Mount the Martin Audio Engineer 818 with racking screws in a 19” cabinet. Use support strips as necessary to

support the rear of the device.

Adequate ventilation and rear-support must be provided. Allow for enough ventilation into the 19” cabinet in

which the Martin Audio Engineer 818 is mounted. Observe the environmental specifications (see appendix 2)

at all times.

When mounting the Martin Audio Engineer 818 in a touring rack, a touring rack with shock-absorbing racking

strips should always be used.

Always install the Martin Audio Engineer 818 in a level plane. A maximum allowable angle of 10 degrees is

acceptable.

Do not use the Martin Audio Engineer 818 in a wet/damp environment.

Do not block any ventilation slot at any time and check the proper function of the fans at regular basis. If the

fans do not operate properly, the lifespan of the device will be significantly reduced and the device may

even fail.

Connecting Audio

Use only certified balanced & shielded audio signal cabling (e.g. Belden 8718, Tasker C208). The connectors on

the Martin Audio Engineer 818 accept 12-pin Phoenix terminal blocks (as supplied). From left-to-right are

INTPUT 1-8 and OUTPUT 1-8. The connections are labelled: (please refer to rear panel layout)

+ For audio hot

- For audio cold

For audio ground

Attention: Martin Audio strongly recommends the use of balanced audio connections only.
