Pressing the [ANALYSIS] button in the Copland
Target Curve 1.0 software starts the measurement and analysis.
During the measurement and analysis process a bar meter is displayed indicating that the
Copland DRC205 is performing measurements and analysis.
See front panel operation and respect the same precautions!
After the measurement and analysis, all graphs are available for your examination in the
Display Area of the Copland Control panel 1.01 software.
You may change the Target Curve and store your own preferred tonal balance in P1-P2,
hereby optimising your stereo system to your own personal preferences.

Please find here a short form guide for designing your own
Target Curves for P1 and P2 .
This guide will provide some tips in regard to usage of the Target Curve filters ( Filter types )
used to tweak the tonal balance of the stereo system.
Peaking Filter
The Peaking Filter has basically the same function as any parametric equalizer band. It is
hereby an advanced tonal control that can be used to attach the response at any frequency
with any bandwidth.
Important note: Respect the guidelines provided in the previous section for
optimum usage and results.
To use the Peaking Filter , select Peaking Filter in Filtertype .
Set the Fc (Attach frequency or centre frequency) of the Peaking Filter by inputting the desired
frequency into the Fc input box.
Select the Q (bandwidth) for the function of the Peaking Filter. Low Q (below 1.0) results in
filters affecting a wide frequency band – and high Q (above 1) results in filters affecting a
narrow frequency band.
Important note: If you do not have full technical understanding of the Q-factor for
filters, then you should not change the
Q factor outside the 0,1-1.0 ranges.
Slide the [ GAIN ] until the desired SPL is obtained – either by gain (up to +6dB) or by
attenuation (up to –6dB).
# " "
: Be careful when applying gain to the system as this may result in
overloading of the Copland DRC205, overloading your amplifier and overloading
your loudspeaker. Copland has already increased insufficient SPL by the
automatic DDRC algorithm!
