Air Flow

This unit uses a forced cooling system in which air comes in through the front opening and goes out the rear.

Rack Mounting

If multiple high-power amp units are mounted in a rack with poor ventilation, the heat from the amps will cause the interior

of the amp to become very hot, causing the performance of the amps to be impaired. In particular, when mounting in a rack

whose back can not be left open, mount according to the following instructions.

Rack:

Leave a gap of 10 cm or more between the rear panel of the rack and the rear panel of the ampliﬁer.

Fan:

Use a fan with 1.5 m

/min or more maximum wind and 5 mmH

O or more maximum static pressure.

Mounting:

Install the fan kit on the top slot or the top panel of the rack and install a blanking panel between two amps.

If the unit is rack mounted and transported frequently, we recommend that the rear of the unit be supported by ﬁtting a pair

of metal brackets, one each side.

Example of mounting

The top ﬁgure shows an example of a fan kit (panels and two fans) on the top slot of the rack. The fans are Minebea 3115PS-

12T-B30 (with 0.9 m

/min maximum wind and 5 mmH

O maximum static pressure).

The bottom ﬁgure is a dimensional diagram of a panel on which two 3115PS-12T-B30 are installed.
