started

Basic Connections
Before terminating any wire,
turnallequipment o and
disconnect theAC power.
Make all appropriate audio
andpower connections to
theMA6000 unit.
On the MA6480A, set the input
sensitivity switches for the
MIC/LINE inputs to the
appropriate position. Select LINE for
line-level signals, MIC for mic-level signals,
or PHTM when using microphones that
require phantom power.
On the MA6008/6018/6000M,
use dip switch #1 for mic/line
selection and dip switch #2 to
supply phantom power.

AmplierConnections
Ensure the loudspeaker power
requirement does not exceed
the HI-Z amp’s available power
output. Add up the total transformer taps of
all the loudspeakers to be powered,
e.g.,four70 V loudspeakers using 10 W
transformer taps require 40 W of power.
Set the HI-Z MODE switch to
either 70 or 100 V to match the
system’s loudspeaker
voltagerequirement.
Ensure the loudspeaker
impedance does not exceed
(notless than) the minimum
load impedance of the LO-Z amplier (4 Ω).
For example, two 8 Ω loudspeakers
connectedin parallel equal a combined
impedanceof4Ω.
Volume and Gain
Before powering up, set all
INPUT LEVEL knobs, rear panel
GAIN knobs, and MASTER
VOLUME to the full counterclockwise
(o)position.
Power on the unit.
Slowly raise the rear panel
GAINcontrol for the
individualinput channels
untilthegreenSIG LED illuminates
(doesnotapplytoMA6480A).
Raise the MASTER VOLUME knob
to the 10 – 12 o’clockposition.
Slowly raise the front panel
INPUT LEVELknobs for the
individual inputchannels.
Adjust the MASTER VOLUME to
the desired overall
listeningvolume.
Adjust the CHANNEL EQ
knobstotailor the treble
andbass response of each
individualchannel.
Adjust the MASTER EQ knobs on
the front panel to set the overall
system response.
Adjust the BALANCE control to
set the relative volume level
between the 70 / 100 V
loudspeakers and the 4–16Ωloudspeakers
(does not apply to MA6000M).
Tel/Page Setup
This 4-pin male Euroblock connector
accepts microphone or line-level signals
and oers selectable phantom power.
Pin4provides a control terminal to initiate
a page announcement via contact closure
or signal activation. When the paging input
is activated, it can trigger a pre-announce
tone, override the AUX inputs and/or override
inputs 1-8. Thesignal can be independently
routed to the Main and/or Zone 2 bus. The
connector has an impedance of 600 Ω and is
shielded from unwantedDCvoltage.
Channel Input
EuroblockConnector
This male 5-pin Euroblock connector accepts
microphone or line-level signals. Pin 4
(Control) can be used for multiple purposes,
including:
• Remote volume control - when
switched to RVC, connecting a 10 kΩ
linear potentiometer between this
terminal and the Ground terminal allows
remote control of the volume level of
thechannel.
• Forcing the input channel on and causing
other input channels to be muted when
set to force on.
Pin 5 (Direct Out) carries a buered and
unbalanced split of the input signal after
the input trim control and before the
inputequalizer.
