Manual-5

The MA 6S will drive an active two-way stereo system when wired as shown. The high frequency drivers run direct from

Channels 5 and 6. The low frequency drivers, requiring much more power, are run from two bridged pairs: Channels 1 and 2
are bridged to one woofer and Channels 3 and 4 are bridged to the second woofer.

CAUTION: 8 ohms is the lowest impedance that can be driven by the MA 6S in BRIDGED mode. If there are two woofers in

each bass cabinet, be sure they are wired in series if they have an individual impedance of less than 16 ohms each.

WIRING NOTE: Whenever connecting any device to the MA 6S Inputs, be aware of signal grounding paths. Connect the

shield to MA 6S Chassis Ground for proper cable shielding. Some installations may permit ground connection to Signal
Ground on the Euroblock, but the best ground is directly to the Chassis.

In addition, since the AC 22 does not get it's ground through the line cord, its chassis should be grounded through either the

rack rails or a jumper wire connecting the chassis' of both units. See the included RaneNote, “Sound System Interconnection”
for a full explanation and proper wiring techniques.
