Thank you for selecting the Klark Teknik DN500 Plus dual compressor / limiter/ expander.The unit continues
the Klark Teknik tradition ofproviding superb audio performance, technical accuracy and rugged reliability.

Do not install this unit in a location subjected to excessive heat, dust or mechanical vibration.

Connection is made by means ofan IEC standard powersocket. The rear panel text indicatesthe voltage range
required for satisfactory operation of the unit.

Before connecting this unit to the mains supply, ensure the fuse fitted is the correct type and rating is as
indicated on the rear panel, adjacent to the fuse holder.

This unit is fitted with a standard fused IEC mains inlet: For safety reasons the earth lead should never be
disconnected.

To prevent shock or fire hazard, do not expose the unit to rain or moisture. To avoid electrical shock do not
remove covers. Refer servicing to qualified personnel only.

This product should only be used with high quality, screened twisted pair audio cables, terminated with metal
bodied 3-pin XLR connectors. Any other cable type or configuration for the audio signals may result in
degraded performance due to electromagnetic interference.

Should this product be used in an electromagnetic field that is amplitude modulated by an audio frequency
signal (20Hz to 20kHz), the signal to noise ratio may be degraded. Degradation of up to 60dB at a frequency
corresponding to the modulation signal may be experienced under extreme conditions (3V/m, 90%
modulation).
