2.4 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.

next paragraph for maximum allowable conductor cross sections.
The connectors on the Martin Audio Engineer 418 accept 12-pin Phoenix terminal blocks (as supplied).
