SAFETY PRECAUTIONS
TRANSPORTATION LATCHES
The SIRUS PRO COMPACT 3 sound system is supplied with a detachable power cable with an IEC
female connector and a male AC connector. Depending on the territory in which the COMPACT 3
system is purchased, the power cable will be supplied with one of a number of male AC connectors
to accommodate the different safety and code requirements of specific countries. All AC cables
supplied with COMPACT 3 products are three pin grounded types.
Under no circumstances should the ground(earth)pin be disconnected or removed.
Your COMPACT 3 System features a Switch-Mode-Power-Supply designed to operate on any AC voltage and line frequency
to convert AC power with maximum efficiency.
When travelling abroad with the COMPACT 3 system, as a standard precaution, always check the local voltage and set the
voltage selector switch located adjacent to the socket on the rear of the mixer / amplifier to the appropriate operating range.
This check must be performed before connecting the power cable. The SIRUS PRO COMPACT 3 has two range settings:
115V or 230V .
Failure to select the appropriate voltage range will cause the unit to go into protect mode, void any warranty and may cause
damage to the unit.
For example, The United States of America is standardized at 117 volts / 60 Hz, Japan operates on 100 volts / 50 Hz. For
both of these countries the range selector must be set to 115V. Countries in the EEC have standardized at 230 volts / 50
Hz., However, there are different types of AC plugs used. For all these countries the selector should be at the 230V position.
When using plug adapters or operating in a territory other than the one in which the unit was purchased, take great care to
comply with local safety requirements and electrical codes of practice.
If you are not sure of the local voltage, wiring codes & colours, AC grounding, or correct procedures for
connection, consult a qualified technician.
Warning
Under no circumstances should the ground pin on the COMPACT 3 or on any of your electrical
equipment be lifted (cut off or disconnected).By following the correct procedures and safety
precautions, risks of severe shock hazard can be minimized. Best of all, avoid operating the
system in conjunction with ungrounded or improperly grounded electrical equipment.
To open and close your COMPACT 3 system, simply follow these guidelines:
1. Place your finger tip under the safety latch and gently lift. When the safety latch has disengaged, lift the main latch to
remove the speaker.
2. To replace, position the speaker on the tower foot ad bring the speaker in to close the engagement with the tower and
latch. Position the latch hook over the speaker notch and close the latch. The safety latch will automatically engage.
Note: These parts are precision engineered and no force is needed to secure them. Careful alignment of parts will ensure
easy operation.

SET-UP SYSTEM VOLUME AND LEVELS
To set system volume and operating levels, be sure to follow these simple set-up guidelines:
1.First,slowly raise the large Left and Right Master volume controls to their 12o'clock notched positions.
2.Use a microphone(or other source)in the same position as it will be used on stage and in the manner in which it will be
used for the event. Slowly bring up the appropriate channel input level control listening for the onset of feedback or howling
or until the required level is reached. Have a helper "walk"the audience area to make sure coverage and levels are sufficient
for your needs. The system's overall volume can be raised simply by rotating the Left and Right Master volume controls to
the desired level.
3. Consider the application and needs of the event and set the System EQ control appropriately. This is best achieved by
playing recorded material of the same type as your show program, or by having an assistant speak into the microphone
while you listen in the audlence area.
For public address (spoken voice), it is advisable to rotate the System EQ sticks up to enhance the mid and high
frequencies, and limit the low frequency content. For large outdoor spaces this will also give the maximum headroom and
output capability. Carefully consider the individual event's needs and set your control for the maximum effect.
POWER TOWER
In setting up the system, the COMPACT 3 Mixing console should ideally be placed where system performance can be
evaluated by the operator. If no ongoing adjustments will be necessary, the mixer may be placed conveniently and where the
cable lengths allow.
Take care to place the Power Tower there the cables will not trip anyone. All cables should be carefully secured.
The storage compartment in the rear of the Tower can hold cables, microphones and other system parts. To open simply
slide the catch upwards and pull open.
The mains (AC) fuse holder is under the IEC (power cord) socket on the right rear of the Tower. To change a fuse, remove the
IEC plug and, using an appropriate tool pull out the fuse holder, Note there is a spare fuse in the fuse holder; the COMPACT
3 utilizes a T6A 250V fuse. Only replace fuses with one of an identical value and size.

SET-UP AND CONNECTIONS
CONNECTOR / LINE CORD - The COMPACT 3 is equipped with a grounding type IEC supply cord to reduce the possibility
of shock hazard. Be sure to connect it to a grounded AC receptacle. DO NOT ALTER THE AC PLUG.
The power mains(AC) fuse and fuse holder are under the IEC(power cord) socket Replacement
fuses must be of the same rating(6A 250V) and size as originally equipped. To replace a blown
fuse, remove the IEC power cord. Pull out the fuse holder and find the spare fuse inside.
Your COMPACT 3 system is capable of running on battery power. The off-white plastic connector on the rear of your
COMPACT 3 is the DC power input connector for connecting the COMPACT 3 with +/- 48 V battery pack.
A small storage compartment can be found on the rear of the COMPACT 3 tower. To access this compartment, simply lift the
latch and pull open the storage door. This compartment is ideal for storing cables, microphones or other items when you are
transporting your COMPACT 3.
Before turning on the Power, please read and heed the safety warnings on page 3.
It is wise to establish a routine for connecting and powering up your sound system. Provided you have a properly grounded
AC outlet or outlet strip with sufficient power handling capacity, plug all sound system equipment into the same outlet or
strip. This will enhance system safety and performance. Take care that the AC circuit is capable of handling the peak power
demands of your system. Consult the product handbooks or a qualified electrician if in doubt.
When setting up, be sure to follow these simple set-up guidelines:
1.First,turn all channel Level, VIP(channel 1 ONLY)and Eff/Aux controls to their full counterclockwise(OFF) positions. Next,
place all EQ sticks in the middle position ("0" position), all Pan and Master controls at 12 o'clock in their center notched
positions. Be sure to set the appropriate input (mic / line switch position)for the source you are setting up.
2.Next,connect each speaker cable to the appropriate left & Right Speaker outputs on the rear tower and on each speaker
front panel with the enclosed cables.
3.Connect all sources such as microphones, tape decks, keyboards etc.,into the appropriate inputs.
4.Finally,check the local voltage and set the voltage selector switch located adjacent to the power input socket on the rear of
the mixer/amplifier to the appropriate operating range.(See Safety Precautions on page 3.)Plug the power cable into the
IEC(power cord)socket end to a properly grounded 3 wire AC power outlet.
POWERING UP
Turn the Power Switch to the ON position. The Power LED will illuminate green and the system will turn on. If other powered
equipment is to be attached to the system, it is always advisable to turn on your COMPACT 3 last. In this way any transient
spikes and thumps caused by other equipment will not be amplified and sent to your system speakers. For the same
reasons it is advisable to turn off your COMPACT 3 system first before turning off the attached equipment.
Should the Power LED not illuminate when the rear panel power switch is operated, check your power connections and
retry. Should the Power LED still fail to illuminate after you have confirmed the power connections, disconnect all cables
and check the COMPACT 3 fuses. Be sure to replace any blown fuses with fuses of the correct value. Reconnect the power
and speaker cables and turn the rear panel power switch on.
Re-set the system by turning on the power switch. If the power LED illuminates red, the system is indicating a thermal
protect mode or cooling problem .Be sure to check the air inlet filter at the base of the unit by removing it and making sure it
is clear of debris.
Turn power off and wait for a few minutes allowing heat to dissipate and the COMPACT 3 to reset itself. If after doing
so the Power LED continues to glow red this indicates a fault with your system and you should consult an authorized SIRUS
PRO service center.
If no audio is present in one of the speakers, check to see if your control settings are correct. Next, unplug the cable from
your working speaker and reconnect it to the other speaker. If the second speaker now works, this indicates that the first
cable is bad, and should be repaired or replaced.

CONTROL FUNCTIONS
1) HIGH - Adjusts the relative level of the high frequency content. Rotating the knob counterclockwise decreases the high or
high frequency response. Likewise, rotating the knob clockwise increase the high or high response is "flat" with no
frequencies increased or decreased.
2) MID - Adjusts the relative level of the mid frequency content. Rotating the knob counterclockwise decreases the high or
mid frequency response. Likewise, rotating the knob clockwise increases the high or mid frequency response. When the EQ
controls are set at their middle position,. the channel frequency response is "flat" with no frequencies increased or
decreased.
3) LOW - Adjusts the relative level of the low frequency content of the channel 1. Rotating the knob clockwise increases the
bass or low frequency response. Likewise, rotating the knob counterclockwise decreases the bass or low frequency
response. Likewise, rotating the knob counterclockwise decreases the bass or low frequency response.
4) EFF / AUX - Adjusts the amount of signal sent to the Reverb processor, and to the EFF / AUX output jack. Reverb can be
used to enhance the sound quality of any performance where appropriate and desired. In the full left position there is no
level sent to the reverb processor or EFF / AUX jack. Care should be taken to set the Reverb return master control to a
middle position or above, before adjusting levels from the individual channel. When the reverb / auxiliary mix is set, overall
levels of reverb can be adjusted at the master control. Keep in mind that while Reverb or effects can enhance a musical
performance or presentation. Too much reverb can make the same performance or presentation unintelligible or
"muffled",Keep your audience in mind when setting reverb levels.
5) PAN - The Pan control features a notched position indicator and adjusts the perceived" position" of the mono signal from
the input within the stereo field created by the two speaker cabinets. Full Left or Right rotation of this control sends the
signal to the that channel only, with no signal sent to the other. The center position sends the same amount of signal to both
speakers.
6) LEVEL - Adjusts the volume level of the individual channel. Rotating the knob clockwise increases the respective
channel's contribution to the "Main Out" mix, while rotating it counterclockwise decreases the volume. Adjust this control
after the COMPACT 3's master output level volume has been set.
7) BAL - The balance control features a notched position indicator and adjusts the perceived"position" of the mono signal
from the input within the stereo field created by the two speakers. Full Left of Right rotation of this control sends the signal to
the that channel only, with no signal sent to the other. The center position sends the same amount of signal to both speakers.

19 & 20 ) MASTER VOLUME LEVEL CONTROLS - The Left and Right Master Volume Controls adjust the output volume of
the COMPACT 3. The Master controls feature notched position indicators. For the majority of applications the COMPACT 3
system has been balanced to operate with these controls at their notched 12 o'clock positions. In situations where more
volume is required the master controls can provide an additional 6 dB of gain when turned to the right of the center position.
Set the system up in the normal manner and adjust levels as necessary. Raise the master volume controls beyond their 13
o'clock positions only after increasing the individual channel level controls. COMPACT 3's internal amplifiers have on-board
processing designed to optimize the system ,s performance when used with the custom designed COMPACT 3 speakers.
21) STEREO / DUAL SELECTOR SWITCH - Allows the COMPACT 3's power amps to be configured as stereo or "dual -
mono". In the Stereo mode, the system operates as a traditional stereo power mixer / amplifier. In the Dual mode, the
channel level controls control set the level for the Main mix(LEFT master volume control) The Rev / Aux controls set the
individual channel levels for the Monitor(RIGHT master volume control). When the Dual mode position is selected with the
switch, the Pan and Balance controls become in operative (you have selected a mono setting for the output). Additionally,
the internal reverb is only sent to the MAIN speaker output. Reverb is not available to the MONITOR speaker output. The
reverb level sends for the MAIN mix are also controlled from the channel DSP / AUX channel controls. The overall reverb
level to the MAIN mix is controlled by the Reverb Master Control.
22)EQ CONTROL - Adjust the EQ sliders the 7 band EQ is connected into the system, when turn off the EQ button, the EQ is
off the audio signal will go directly to the system without EQ.
23) SYSTEM EQUALIZER - Adjust the amount of frequency increase or decrease in the channel. The left and right channels
are adjusted simultaneously at same time and same pace. Set frequencies are at 60Hz,160Hz,400Hz,1KHz, 2.5KHz,6KHz,
16KHz , adjusting range within +/-12dB; When the sliding stick is at the middle position, the frequency response is "flat" with
no frequencies increased or decreased; When sliding the stick up increases the frequency response of that band, when
sliding the stick down decrease that band's frequency response. To set the EQ, start with this control from the middle("0dB"
marked) position. Simply slide the sticks until your desired sounds are there.
