WARNING: To reduce the risk of fire or electrical shock,
do not expose this appliance to rain or moisture.
Electrical equipment should NEVER be kept or stored in
damp environments.
Unpacking / Setup: Please check your amplifier for any
damage after unpacking (before connecting) and contact
your dealer in case of any related complaints. Take care
of choosing your installation place and the correct AC
connection. If built into a case, be aware that the depth
and the weight of the amplifier does require an additional
fixing on the backside or the use of rack shelf supports.
Never mount the amplifier in a rack just by fixing it on the
front plate - we can show no responsibility for damage
on the rack or the amplifier in this case.
SERVICE INSTRUCTIONS
•
•
Disconnect power cord before servicing
Replace critical components
with factory parts or recommended
equivalents
only
•
For AC line powered units - Before
Always try to separate low level cables (input cables)
and high level cables (AC net and speaker outputs) to
avoid interference.
returning repaired unit to user, use an
ohmmeter to measure from both AC plug
blades to all exposed metallic parts. The
resistance should be no more than
100,000ohms.
DOUBLE INSULATED - When
servicing use only identical
replacement parts
Check the total maximum power of
your AC wall outlet if you connect
several units to one wall outlet and
avoid to overload the wall outlet,
which could cause fire.
For 220-volt use in USA, use NEMA style 220-volt plug.
For other countries use proper plug for local outlet.
Health Advice: This unit produces and absorbs
electromagnetic radiation. The strength of radiation and
the sensitivity for disturbing interference matches the CE
requirements. A corresponding sign is printed on the
backside of the unit. Any change or modification may
affect the behavior of the unit concerning
electromagnetic radiation, with the CE requirements
eventually not to be met any more. The manufacturer
takes no responsibility in this case.
Please record the serial number of your unit as shown on the back of the chassis as well as the
name of the dealer from whom you purchased the unit. Retain this information and your original
purchase receipt for your records. Please return the enclosed warranty card to register unit with us.

CONGRATULATIONS...
Thank you for choosing a NUMARK power amplifier. These units
are designed to provide a good combination of power, audio clarity, and
reliable operation. The basic circuit has been kept as simple as possible
to reduce the amount of components, thereby shortening the signal path,
coloration and the chance of component failure. However, we opted to
add what we regard as essential protection against overheating, short
circuits and power on transients.
An efficient heat dissipation system, comprising a high surface area
heatsink coupled with one or two fans (depending on power rating of
amp), ensures quiet and reliable cooling.
The sound quality and sturdy construction of the makes these amps
ideal for a multitude of amplification tasks, from installations, mobile DJs,
home studios, houses of worship and touring bands.
Since all of the amplifiers are similar in operation, this manual
serves for all models. Please take the time to read this manual before
connecting and operating your unit, as there is important information
contained within.

1. Power Switch- Press the upper side to turn amplifier on; press the lower side to turn the
unit off.
2. Status LEDs- The red Standby LED will light when the amplifier is turned on. It will stay lit
about 3 seconds while the amplifier circuits stabilize. After that, the red LED will turn off and
the green Normal LED will glow that amplifier is ready to operate.
3. Level controls- Rotate controls clockwise to increase volume.
4. Signal indicators- Light up when the signal input provides greater then 0.2 watts output.
5. Over indicators- Light up when the input signal levels exceed maximum output and
clipping occurs. Consistent lighted of these LEDs can cause both amplifier and speaker
damage. Always avoid clipping.
6. Protect indicators- Light up when one of the built-in protection circuits is activated.

7. Unbalanced inputs- Connect mixer outputs with ¼” input plugs for right and left channels.
8. Balanced inputs- Connect a balanced signal through XLR input connectors. These should be used for all
long cable runs. Please note: Pin 1 Ground, Pin 2 Positive (+), Pin 3 Negative (-)
9. Stereo/Bridge Mode Switch- Bridged mono operation is easily achieved and gives you the output power
of both channels on just one mono output. For successful bridge operation, follow these instructions:
•
•
•
Set the Mode Selector to Bridge.
Connect a mono input signal to right input jack, channel 1.
Use only the terminal post outputs for speaker wiring, not the Speakon outputs. Connect the
speaker load to the red terminals of each channel. Please confirm the (+) terminal of speaker to
channel Right and the (+) terminal to channel Left. Do not use the black terminals of each channel.
The minimum load impedance in bridge mode is 8 Ohm.
•
•
To adjust level use channel 2 control and leave channel 1 level at zero.
10. Ground/Lift-Switch- To eliminate the ground loops between this amplifier and a preamplifier. Never
remove the center grounding pin of the AC plug!
11. Output Terminals- Output connections are to binding posts, which are identified as to polarity with a red
and a black terminal. We suggest the use of dual banana plugs as a convenient and reliable method of
hook-up. They allow rapid removal for polarity reversals, which is handy in the check-out and adjustment of
multi-element biamplified and triamplified sound systems. Heavy Class 11 wire may be used by unscrewing
the large plastic portion of the output terminal and inserting the wire into the hole provided. It is extremely
important when making wire connections that no wire strand or end touches the adjacent terminal, shorting
the output. Please do not use these outputs simultaneously with the speakon outputs, only alternatively.
CAUTION: Never strap the two red output terminals together (in parallel). Never connect either red
output to chassis ground.
12. Speakon outputs. For better contact security, use of these outputs is strongly recommended in all
applications, especially mobile systems. Do not use these outputs simultaneously with the output terminals,
only alternatively. Note the correct pin designation for the used speakon connectors: pos=1 + / neg = 1- /
2+, 2- not connected.
13. Fuse holder. This fuse holder contains AC primary fuse. Fuse should be replaced by same type fuse when
this is blown out. Disconnect the amplifier from AC mains before replacing a fuse. If they continuously blow,
stop replacing fuse and refer servicing to qualified personnel.
14. AC Power cord socket. Plug-in the supplied AC cord here and connect it into an AC outlet.

Notes on protection circuits:
These amplifiers are equipped with different protection circuits to prevent any damage to the amplifier
itself or the speakers due to improper operation circumstances.
1. Overheat- For low mechanical noise emission, the built-in fan operates at low speed as long as
the internal heat sink keeps cooler than 55 degrees Celsius. The fan will speed up to maximum
speed when this temperature is exceeded. When the heat sink temperature exceeds 90 degrees
Celsius, the amplifier will shut down the outputs to avoid overheating. The outputs will be
automatically re-activated when the heat sink comes below 70 degrees Celsius.
2. DC on output- When DC is detected on the output, the amplifier will shut down the outputs to
avoid speaker damage.
3. Short circuit on the output- When a short circuit is detected on the output, the amplifier will shut
down the outputs to avoid damage to itself.
