Do not operate the Copland DRC205 before the above
Operational Set-up
has been done.
Read the following instructions carefully before starting the automatic room analysis and
calibration!
When having correctly connected the Copland DRC205 to your audio system and having
performed the
Operational set-up
, then the Copland DRC205 is ready for room acoustics
analysis and automatic systems calibration.
The following describe the analysis and calibration when operated directly from the front
panel of the Copland DRC205. ( For operation with an external PC/Computer – please refer to
“
Operating Copland DRC205 from a PC/computer
” ).

Switch off all signal sources in your audio system! Select the TAPE
MONITOR as playback (if the Copland DRC205 is connected to a TAPE MONITOR loop as
recommended – otherwise select the source, the Copland DRC205 is connected to)!
Adjust the volume control on your amplifier (or pre-amplifier) to approx. 1:00-2:00 o’clock
position before starting the measurements. It is important to perform the measurements at a
sufficiently loud volume to avoid any non-desired noises (e.g. from traffic or other external
noise sources) influencing the measurements.
Important note: Do not change the volume on the amplifier (or pre-amplifier) during
the automatic room analysis and calibration procedure!
Explanation: The test signals of the Dynaton Digital Room Compensation (DDRC)
engine are designed to be as insensitive to background noise as technically
possible. However, it is recommended that you set the volume control at 1:00-2:00
o’clock position for best possible measurements and keep silent during the
measurement sequence.
