(1) INPUT LEVEL knobs adjust the volume
of the corresponding input signals.
(2) MASTER EQ knobs adjust the bass
(LO), middle (MID – MA6480A only),
andtreble (HI) response.
(3) EQ SWEEP knobs (MA6480A)
adjustthe frequency and bandwidth of
the LO, MID and HI equalization knobs.
(4) AUX EQ knobs adjust the bass (LO) and
treble (HI) response of the AUX INPUTS.
(5) AUX knob adjusts the gain of the
AUXINPUTS.
(6) ZONE 2 knob adjusts the level of the
ZONE 2 OUTPUT.
(7) AUX SELECT buttons determine which
of the 4 AUX INPUTS are included in
the main mix. The activated button
illuminates while the other inputs
are muted. Pressing an already active
button mutes all 4 inputs.
(8) VU METERS indicate the signal level of
the main mix and zone 2.
(9) MASTER VOLUME knob adjusts
the master output level of the main
mixbus.
(10) INDICATOR RING glows yellow when
the power is on, and turns red at onset
of clipping.
(11) POWER switch turns the unit on
and o.
(12) MIC/LINE INPUT accepts balanced or
unbalanced, microphone or line-level
signals via XLR/TRS combination jack.
(13) EUROBLOCK INPUT accepts
microphone or line-level signals via
5-pin Euroblock connector. From left
to right, the pins are ground, positive,
negative, control, and direct out.
(14) EUROBLOCK INPUT (MA6480A)
accepts microphone or line-level
signals via Euroblock connector.
Channels 1 and 2 have pins for ground,
positive, negative, andchannel 2 has
a mute pin.
(15) MIC/LINE switch (MA6480A)
optimizesthe input for line-level,
microphone-level, or microphone-level
with phantom power.
(16) PRIORITY switch (MA6480A)
determines the muting of channel2
when channel 1 is active. In VOX
mode, channel 1 remains o until it
receives an audio signal, which then
mutes channel 2 momentarily. In OFF
mode, channel 1 remains o until it
is remotely activated by shorting the
MUTE pin to ground, at which time
channel 2 is muted. In the ON position,
channel 1 functions normally with
nopriority.
(17) CHANNEL EQ knobs adjust the treble
(HIGH) and bass (LOW) frequencies of
the channel.
(18) GAIN knob adjusts the gain of the
channel input.
(19) INPUT DIP SWITCHES control various
aspects of the channel. Refer to the dip
switch chart for more information.
(20) REMOTE connector provides terminals
for common, +5 VDC, remote volume,
AUX input select, and power toggle.

to an optional remote control.
Thecorresponding switch determines
whether the remote volume control
aects the main signal or the
AUXinputs.
(21) AUX INPUTS allow the connection of
4 stereo signals that are summed to
mono and included in the main and/or
zone 2 mixes.
(22) TEL/PAGE INPUT allows connection to
a paging system via detachable 4-pin
Euroblock connector.
(23) PAGE DIP SWITCHES engage
various functions and features of
thePAGEinput.
(24) CHIME knob adjusts the volume
of a chime that sounds before
anannouncement.
(25) MUTE knob adjusts how much the
PAGE signal overrides all other signals.
(26) MOH knob adjusts the level of the
signal on the Music on Hold bus.
(27) PAGE knob adjusts the level of the
PAGE INPUT.
(28) BRIDGE INPUT receives a balanced
signal from another mixer,
allowingmultiple units to be
daisychained.
(29) BRIDGE OUTPUT sends a
balanced signal to another mixer,
allowingmultiple units to be
daisychained.
(30) ZONE 2/MOH OUTPUT sends line-level
audio from the Zone 2 mix, and sends
a line-level Main mix to a telephone's
Music-on-hold input.
(31) MAIN DIP SWITCHES assign
routing options that aect audio
from the aux inputs, tel/page input,
andinternalchime.
(32) PRE OUT/LO-Z output provides a
balanced, line-level send and return
for insertion of external processing
equipment into the main mix before it
enters the LO-Z output.
(33) PRE OUT/HI-Z output provides a
balanced, line-level send and return
for insertion of external processing
equipment into the main mix before it
enters the HI-Z output.
(34) AMPLIFIER OUTPUTS sends the
main mix signal to LO-Z and/
orHI-Zloudspeakers.
(35) HI-Z MODE switch selects between
70V or 100 V HI-Z operation.
(36) BALANCE knob adjusts the relative
output of the HI-Z and LO-Z ampliers.
(37) MAIN MIX OUTPUT (MA6000M)
sendsa balanced mic or line-level
signal to an external amplier.
(38) MAIN MIX LEVEL switch (MA6000M)
sets the main mix output to either mic
level or line-level.
