Front Panel Operations and Connections
Input 1 4 These rotary knobs control the level of Inputs 1-4 in the overall mix. A good level to
begin with is the 12:00 position. Then adjust to achieve the desired level. Inputs 1-4 can be
connected to dynamic microphones, condenser microphones or line level sources like CD or music
Players. Always set the back panel Line/Phantom/MIC switch in the correct position corresponding
To the type of connected source.
Aux – This rotary knob controls the level of the back panel AUX input.
Note: iPods and MP players have their own volume control. When using a hand held music
player, start with the AUX set to the 12:00 position and use your hand held music players
built in volume to adjust the level.
Bass - The bass control s a shelv ng type equal zer that boosts or cuts
bass frequenc es at 100Hz +/- 12 dB. The center “0” pos t on does not
affect the s gnal. Equal zers should be used spar ngly. Too much boost
can cause feedback when us ng m crophones.
Treble - The Treble control s a shelv ng type equal zer that boosts or
cuts bass frequenc es at 10kHz +/- 12 dB. The center “0” pos t on does
not affect the s gnal. Equal zers should be used spar ngly. Too much
boost can cause feedback when us ng m crophones.

Master - The Master ga n control controls the overall output of the
ampl f er. Pay close attent on to the output OL LED. The LED prov des
v sual feedback to the levels n the ampl f er. When the OL “RED” LED
s l t or flash ng the ampl f er s be ng overloaded. Immed ately turn
down the Master volume control. Re-adjust the Input level controls to
the des red m x and then adjust the Master level control to the des red
volume where the OL LED s not sol dly l t.
NOTE: When us ng the V-RVC remote control, set the ampl f er master
volume to 75% then control the master volume remotely from the V-
RVC.

Zones 1 4 The zone 1-4 rotary knobs control the audio level of zones 1-4. The push buttons
control the ON/OF status of each zone. The ALL button sends audio to all zones simeltaniously
which is comonly refered to as ALL CALL paging. Please note that when connecting speakers to
the back panel zone 1-4 outputs any individual zone can have a maximum of 120 watts / 70V
connected and all speakers in all zones combined cannot exceed 240 watts at 70V.
Each zone rotary volume position provides a diferent output voltage as follows:
1-10V, 2-22V, - 1V, 4-44V, 5-70V, 6-100V. When using 70V transformer coupled speakers never
exceed a volume setting of 5 on any individual zone. Adjust your overall system volume using the
master volume control.

Power The Power switch applies power to the amplifier.
Output LED's – The Output LED ladder displays the amplifier output level between ON
and overload. It's good practice to keep the output level below clipping.
It's normal for the clip LED to flash momentarily with higher level program material
and peaks in program material. If the clip LED lights solid the amplifier is being overloaded.
This could cause damage to the amplifier and your speakers. Always keep the master volume
level below clipping to ensure long term stable amplifier operation.
MP3 Player – The X-7240-4 is equiped with an MP player that is capable of playing music
stored on USB thumb drives or SD/MMC digital storage cards. This is an excellet way to play
non-stop commercial free background music from your music library.

Mute SEN – The Mute SEN adjusts the level of override. Fully counter clockwise reduces
the sensitivity where more of the bacgroung music would be heard. A high input level would be
necessary to trigger the override circuit. Fully clockwise increases the sensitivity where a low
input level would trigger the override circuit and the background music would be completely
muted. Adjust this control to achieve your desired results.
Inputs 2 4 – Inputs 2-4 are identical and can be used to connect Dynamic Microphones
(no phantom power necessary), Condenser Microphones (phantom power is necessary),
or line level sources like CD players, AM/FM tuners, DVD players, set to cable boxes
or music servers (do not use phantom power). Inputs 1-4 will accept balanced XLR connectors
as well as 1/4” 6. mm type phone jacks. Caution: always select the approriate
corresponding switch position before making connections. Applying phantom power
to a line level source can cause failure to the connected source.
AUX – Connect music sources like CD/DVD players, AM/FM tuners, set top cable boxes or any
line level music source here.
Line Out – This output sends the unbalanced pre-amplified mixed signal to other devices like
addional amplifiers where more power is needed. The AUX can also be used to connect
recording devices to record the pre-amplified signal.
PRE OUT/AMP IN – This is a loop output/input. If the loop connector is removed the pre-amp
signal from the internal mixer will not be broadcast. The amp-in is simply a line level audio
input. These connectors are most commonly used to send the pre-amplified signal from the
internal mixer to an audio processor like a compressor or equalizer then the processed
signal is sent back into the amplifier through the AMP IN jack to be broadcast.

AC Power Inlet – Connect the supplied AC power cord in here. Only use the supplied power
cord or equivilent 14awg CSA/UL approved power cord.
AC Voltage Selector – This slide connector changes the AC voltage from 110-120V 60Hz
(North American Standard) to 220-240V 50Hz (European Standard). The unit ships with a
standard North American power cord and the switch set to 110-120V. For use outside North
America use a 14awg AC cord with a European type plug and change the fuse.
110-120V Fuse:T12AL 250V
220-240V Fuse:T6. AL 250V
DC 24V – 20A – Emegency backup DC power supplies can be connected to the unit using
the DC input. The DC input is polarity sensitive. Always insure the polarity of the connected
power supply is consistent with the polarity of the unit.
COM/4ohm/25V/70V/100V – These are the speaker level output terminals. The COM or
common terminal should be connected to the speaker negative -. Choose either
4ohm, 25V, 70V or 100V as the positive + to connect to your speakers. Note that all the
connected speakers should be coupled to a transformer that corresponds to the
output voltage. Example: 20 speakers which all have 10 watt 70V transformers. Connect the
speakers in parallel. Connect the speaker – negative to the COM terminal and connect the
speaker + positive to the 70V terminal. Never exceed 240 watts in combined speakers. We
recommend that installers should maintain 0% headroom of 170 watts total.
CAUTION: Never connect 4ohm, 8ohm or 25V speakers to the 70V or 100V terminals. This
can cause amplifier failure and void your warranty. If you are unsure how to connect this
amplifier to your speakers call or e-mail Factor Electronics for technical support prior to making
any connections.PH: 778-800-1918 [e-mail].

TEL INPUT – Th s s a balanced aud o nput that s des gned to accept
s gnals from an analog telephone output. Due to the var ed output
levels from d fferent telephone systems we have prov ded a level
control that allows prec se level adjustments.
NOTE: The TEL INPUT automat cally overr des all s gnals n the pre-
ampl f er and broadcasts the page when an announcement s made
through the telephone system.
COM Z1/Z2/Z3/Z4 – The X-7240-4 provides 4 independent output zones. The zones can be used
to send background music and paging to any of the 4 zones or all zones simeltaniously with the
ALL button. Individual volume control is provided for each zone. The zone audio signal is taken
after the pre-amplifier. All audio sources, mic or line will be braodcast in the selected zone.
Connect the zone outputs exactly the same as the main outputs using the common COM as the
negative – and the Z1/Z2/Z /Z4 as the positive +. The X-7240-4 is a 240 watt amplifier. Never
connect a speaker load that exceeds 240 watts in total. (ALL OUTPUTS COMBINED)
CAUTION: Each zone is capable of a maximum of 120 watts and a maximum of 240 watts all
zones combined. Never connect more than 120 watts to any single zone.
When using 70V speakers set the front panel zone volume to 5 or less. The number 6
position provides 100V at the ouptuts and should not be used with 70V speakers.
TRANSFORMER ISOLATION – Many telephone systems need to be phyisically isolated from
the amplifier and can pass DC voltages from the phone system paging outputs. The X-7240-4
provides an internal transformer which blocks potentially harmful DC voltages and effectivly
isolates the X-7240-4 from the phone system which reduces noise.
MOH OUTPUTS: MOH is Music On Hold. The X-7240-4 provides a line level 600ohm
output and an 8ohm 1watt speaker level output. Carfully check the reccomended input
of the phone system to match the X-7240-4 MOH outputs. The 8ohm 1W output can be
used to power a speaker. This is usefull in lobbys and waiting rooms where the music
will be braodcast but the paging will not be braodcast. The MOH input is taken from the
AUX input jack and the MP player providing uniterupted music for phone systems and lobbys.
