Mix internal channel loop-through (0x29)
Each internal processing channel can receive two possible sets of inputs at the inputs to the
Mix#1 block. The inputs can come from the outputs of the interpolation block as normally
occurs (CnMXLP = 0) or they can come from the outputs of the Mix#2 block. This enables
the use of additional filtering after the second mix block at the expense of losing this
processing capability on the channel.
EQ bypass (0x2A)
EQ control can be bypassed on a per channel basis. If EQ control is bypassed on a given
channel the prescale and all 10 filters (high-pass, biquads, de-emphasis, bass management
cross-over, bass, treble in any combination) are bypassed for that channel.
Tone control bypass (0x2B)
Tone control (bass/treble) can be bypassed on a per channel basis. If tone control is
bypassed on a given channel the two filters that tone control utilizes are made available as
user programmable biquads #9 and #10.

For n = 1 to 8:
0: inputs to channel n MIX#1 engine from interpolation
outputs - normal operation
1: inputs to channel n MIX#1 engine from MIX#2 engine
outputs - loop operation.
For n = 1 to 8:
0: perform EQ on channel n - normal operation
1: bypass EQ on channel n.
