System Connections
Dual Mode
In dual mode connect individual sources to inputs A, B, C and D and set all the
link / dual switches to dual. Channel A's input will output from out A, channel B's
input will output from out B and so on. Each individual output uses pins +1,-1 or
you can connect to out A/B with 4 core cable, where pins +1,-1 are for channel A
and pins +2,-2 are for channel B. The same applies to out C/D, where pins +1,-1
are for channel C and pins +2,-2 are for channel D. This type of arrangement
could be used for 2 way active speakers, where channel A would be bass Left
and channel C would be bass Right. Channel B would be HF Left and channel D
would be HF Right. If 4 core speaker cable was used then the whole system
could be connected from out A/B and out C/D. Note, this arrangement would
only work if the speakers were wired pins +1,-1 to the woofer and pins +2, -2 to
the HF unit.
Link Mode
If the link / dual switches are set to link, then adjacent channels will receive the
same input. This mode is useful if you only have 1 or 2 input sources but want
to use all 4 amplifier channels. Typical arrangements could be powering 4
speakers from a stereo output, in which case you would connect the left output
to input A and the right output to input C. Set the B-A link switch to link and the
D-C link switch to link. The C-B link switch should be set to dual. If all the link
switches were set to link, then an input to CH A would output on all 4 outputs.
Bridge Mode
Bridge mode can be set independently for channels A-B and C-D. This allows
for different configurations. If a 2 channel amplifier is required then set both
channels dip switches to operate in bridge mode and set all the link / dual
switches to dual. Use inputs A and C and out A/B and out C/D for the outputs.
Pins +1 and +2 should be used on these outputs. Note that the minimum load
per bridged output is 4 ohms. If a 3 channel configuration is required, use
channels A and B for left and right and bridge channels C and D. For this
configuration inputs A, B and C would be used, input C would be the input
for the bridge channel. Set channels C and D's dip switches to bridge and
use out C/D for the bridge output. Pins +1 and +2 should be used on the
bridged output. The minimum impedance that can be connected to the bridge
output is 4 ohms and the minimum impedance that can be connected to output
A or B is 2 ohms.
