Drawmer S3 Multi-Band Stereo Tube Compressor - Manual (Page 4)

4 DRAWMER S3 O
PERATOR’S M ANUAL
The S3 is designed for standard 19" rack mounting and
occupies 3U of rack space. Fibre or plastic washers may
be used to prevent the front panel becoming marked by
the mounting bolts. Always connect the mains earth to
the unit.
Because the S3 contains ten valves it will generate more
heat than a simple solid state unit. Avoid mounting the
unit directly above power amplifiers or power supplies that
radiate significant amounts of heat. In addition it is advised
that you leave at least 1U of space above to allow heat to
dissipate. Alternatively, a fan should be fitted somewhere
near to the rear of the unit to circulate cooler air and help
expel any excess heat. (see fig. 1).
It is also recommended to the S3 is mounted horizontally
to allow heat to escape vertically through the vents on the
lid. To mount at an angle may cause the S3 to overheat
which will damage internal components (see fig. 2).
