CPL circuit
The CPL (Coupling) circuit compensates for effects between the cabinets
when building closely coupled arrays. CPL begins gradually at 1 kHz,
with maximum attenuation below 400 Hz, providing a balanced
frequency response when Qi10 cabinets are used in arrays of two or
more. The function of the CPL circuit is shown in the diagram opposite
and can be set in dB attenuation values between –9 and 0, or a positive
CPL value which creates an adjustable low frequency boost around
65 Hz (0 to +5 dB).
Operation with E-PAC
Selecting Q10 mode enables the E-PAC to drive one Qi10 loudspeaker.
LO IMP mode configures the E-PAC to drive a maximum of two Qi10
loudspeakers with a 6 dB reduction in input level to the loudspeakers.
For acoustic adjustment the functions CUT and CPL can be selected. The
characteristics of the CUT and CPL settings are explained in the previous
section "Operation with D6 or D12 - Controller settings".
The E-PAC CPL circuit creates a 3 dB attenuation corresponding to the
-3 dB curve shown in Fig. 4.
