Installation requirements

The Martin Audio Engineer 418 is designed for 19” rack-mount use.

Mount the Martin Audio Engineer 418 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 418 is mounted. Observe the environmental specifications (see appendix 2)

at all times.

When mounting the Martin Audio Engineer 418 in a touring rack, a touring rack with shock-absorbing racking

strips should always be used.

Always install the Martin Audio Engineer 418 in a level plane. A maximum allowable angle of 10 degrees is

acceptable.

Do not use the Martin Audio Engineer 418 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.
