IBM PC compatible USB port interface connector for
communication between a Windows 98/ME/2000/XP compatible PC/Computer
and the DRC205.
The connection can be used during set-up and calibration – or by advanced use of the
DRC205.
Connecting a PC/Computer with to the DRC205 is not required.
The Copland DRC205 can be operated as stand-alone unit without any external
usage of a PC/computer.
Advanced and professional users may prefer to set-up and calibrate the unit and the audio
system by help of an external Windows PC/computer. This increases the user flexibility of the
unit, but also makes set-up and calibration more complex.
If external PC/computer assisted operation is desired, then the [Computer] connection is only
necessary during set-up and calibration of the unit and the audio system.
Reduce the volume control on the amplifier (or pre-amplifier) during connection or
disconnection of the PC/computer! This provides optimum protection to our
loudspeakers.
The front-panel keys are DEACTIVATED when an external Windows compatible
PC/Computer controls the unit!
Connect the Windows PC/computers USB port to the [Computer] connection of the DRC205
before set-up and calibration of the unit and your audio system.
The computer does not need to be connected to the unit during normal playback
operation. However, the Windows compatible PC/computer can be used to control
the DRC205 if desired. (This is an advantage during manual set-up of P1 and P2
user programmes.)
Contact your dealer in case your PC/Computer is not Windows 98/ME/2000/XP compatible
and ask for potential updates of the DRC205 unit for support of non-compatible computers. (At
the closing of hereby User Manual only Windows compatible PC/Computers are supported by
the Copland DRC205.)

The [High-Pass] selector corresponds to the Subsonic protection
filter indicators on the front panel.
The [High-Pass] selector is a 10-position rotary switch that must be preset according to the
audio system and loudspeakers used with the DRC205.
Important note: The [High-Pass] selector is ONLY active during set-up, calibration,
test and measurements! The setting has no negative impact upon the sonic
performance during playback. The function is designed only to protect your
loudspeakers during set-up, calibration, test and measurement!
[
] sets the high-pass filter (subsonic protection filter) at a cut-off of 16 Hz.
[Position 1] should ONLY be used in audio systems featuring large and rugged loudspeakers
capable of handling subsonic frequencies at FULL power!
It is recommended that [Position 1] is only used in audio systems featuring rugged 12”-15”
woofers or similar high-performance/high-power subwoofers and for laboratory measurement.
