There are two ways to connect a Sub to the CXA61/81.
It features both a dedicated Sub Out and also a Pre out.
**Sub out **- Connect to the input on an active subwoofer, if required.
Note: There is a low pass filter of approximately 2.3 kHz applied to the Sub Out, no frequencies above 2.3 kHz will be sent to a subwoofer
connected to this output. This is so that there is minimal phase added by the CXA at the Sub Out frequencies.
The crossover frequency can be adjusted on the Subwoofer itself.
Pre-out - For connection to the unbalanced inputs of a power amplifier or active subwoofer.
Note: There is not a low pass filter applied to the Pre-Out, so the full frequency range will be sent to a subwoofer connected to the Pre-Out.
