REAR PANEL DESCRIPTION
햲
INPUTS:
These are balanced Euroblock connectors. Cable should include two wires with shield. Euroblocks accept up to
12 AWG wire. The shield may be attached to either chassis or signal ground. For unbalanced sources consult the included
RaneNote, “Sound System Interconnection.”
햳
OUTPUTS:
Connect the speaker(s) to each of the six Channels by means of the Euroblock connectors with 18 to 12 AWG
wire (See
햴
for Bridged operation).
햴
NORMAL/BRIDGED switch:
With the switch in the
out
position and the red Bridged indicator
on,
the MA 6S is operating
in BRIDGED mode. The MA 6S utilizes the BRIDGE switch to make internal connections between each pair of Channels:
1&2, 3&4, and 5&6. Whenever a signal is connected to an odd numbered Channel (say Channel 1), the next even-numbered
Channel is driven
inverted
when the BRIDGE switch is activated. Connect Inputs to
odd
Amplifier Channels only (1,3,5),
and connect speakers to the “+” terminals of each Channel pair as shown on the MA 6S chassis silk-screen. When the
BRIDGE switch is inactive, the internal connection is defeated and both Channels operate independently.
햵
AC line cord:
Plug this into a
grounded
l20 VAC AC outlet (or 230 VAC if the MA 6S is internally wired for 230 V
operation).
햶
Line FUSE:
For 120 volt operation, use only a 15 amp 250 volt
Fast-blow
(or Normal blow—
not Slow blow
) fuse, 1.25"
long, such as Buss ABC-15 or equivalent. For 230 volt operation use Buss AGC-8 or equivalent.
햷
Fan filter:
This washable filter may easily be removed for periodic cleaning by gently pulling on the black plastic housing
and then lifting it away–perform this feat with the fan
off
, of course. Once the filter is removed, rinse it under hot tap water;
use dish soap to cut through particularly stubborn “tav sludge.” The MA 6S draws a tremendous amount of air to ensure
proper cooling and resultant long term reliability. Check and clean the filter as often as necessary, especially if the THER-
MAL overload indicator ever comes on.
IMPORTANT: Keep this filter clean to ensure proper cooling and reliability of the MA 6S. Never remove the filter with the
unit plugged in.
