CA-6220/8220
STEREO POWERED MIXER
3. MASTER SECTION 2
1. DIGITAL EFFECT SECTION
This section lets you control the CA-6220/8220’s
internal digital signal processor. The ON switch
selects between input from the internal DSP and
input from the EFFECT RETURN 2 jack.
2. EFFECT SEND CONTROLS
These controls adjust the overall output levels of the
effect mixes that are set up using the EFFECT 1 and
EFFECT 2 controls of each input channel. The EFFECT
SEND 1 control sets the overall level of the signal that
appears at the EFFECT SEND 1 jack. The EFFECT
SEND 2 control sets the overall level of the Effect 2
mix signal, which is sent to both the EFFECT SEND 2
jack and the internal digital signal processor. These
controls should be used to optimally match the effect
mix output levels to the input sensitivities of the effect
signal processors used.
3. EFFECT RETURN JACKS
The output from external effect units fed by the
EFFECT SEND jacks can be returned to the main pro-
gram mix via these 1/4” phone jacks. Note that both
effect circuits have stereo EFFECT RETURN jacks,
allowing the CA-6220/8220 to accommodate effect
devices with stereo output. To return a monophonic
effect signal to both channels of the master stereo
mixing bus, use the EFFECT RETURN L jack. (The R jack should be left open.) The level of the signals input
by these jacks are adjusted by the corresponding EFFECT RETURN controls. The nominal input level for
these jacks is +4dB.
4. EFFECT SEND JACKS
These 1/4” phone jacks deliver the corresponding effect mix signals to feed external effect devices. Note
that the EFFECT SEND 2 output is active even when the internal digital signal processor is turn on. The
levels of the signals output by these jacks are adjusted by the corresponding EFFECT SEND controls. The
nominal output level for these jacks is +4dB.
