Please check before using
- Power supply
The AC line voltage must be in ac-
cordance with the following:
Voltage: ~230V±10%
Frequency: 50Hz/60Hz
- Mode selection
The dip switches (located on the rear
panel) confi gure the amplifi er for eit-
her stereo, parallel or bridged mono
mode. Factory default setting is Ste-
reo Mode.
Stereo mode
In Stereo Mode, both channels ope-
rate independently, with their input
attenuators controlling their respec-
tive levels. Signal at channels A´s
input produces output at channel A´s
output, while signal at channel B pro-
duces output at channel B´s output.
Recommended minimum nominal
load impedance for stereo operation
is 4 ohms per channel.
Parallel mode
When set to Parallel Mode, a signal
applied to A´s input will be amplifi ed
and appear at both channels outputs.
Only channel A input may be used.
Bridged mono mode
Bridged mono mode straps both am-
plifi er channels together to make a
very powerful, single - channel amp.
One channel “pushes“ and the other
“pulls“ equally, doubling the power.
Signal is applied to the Channel A
input only. Signal level is determined
by CH A level control.
Operating instructions
- Clean or replace dust fi lter
From time to time or after using this
unit in dusty environments the
dust fi lter of the amplifi er should be
cleaned or replaced. To take off the
front panel, remove the
corresponding Phillips-head screws.
Take out the fi lter foam, clean or re-
place it and assemble the front
panel again.
Clean the fi lter foam with warm wa-
ter and a little bit of rinsing agent.
Take care to dry the the foam
completely before reassembling it.

V12/2009
1. Keep this manual for future reference.
2. Heed all warnings.
3. Follow all instructions.
4. Do not use this unit near water.
Do not spill water or other liquids into or on the unit.
Do not operate the amplifi er while it is wet or standing in liquid.
5. Clean only with dry cloth.
6. Do not block the air intake or exhaust ports.
7. Do not operate the amplifi er near heat producing devices such as radiators, heat
registers, stoves or other apparatus that produce heat.
8. Always operate the unit with the chassis ground wire connected to the electri-
cal safety earth. Do not defeat the safety purpose of a grounding-type plug. A
grounding type plug has two pins and a third grounding prong. The third prong
is provided for your safety. If the provided plug does not fi t into your outlet,
consult an electrician for replacement of the obsolete outlet.
9. Connect only to AC power outlets rated 230-240V, 50-60Hz.
10. Do not use this amplifi er if the power cord is broken or frayed. Protect the pow-
er cord from being walked upon or pinched particularly at the plugs and the
point where it exits from the apparatus.
11. Only use accessories specifi ed by the manufacturer.
12. The unit is intended to use in a 19” rack. Follow the mounting instructions.
When a rack on wheels is used, use caution when moving the loaded rack to
avoid injury from tipping over!
13. Unplug this apparatus during lightning storms or when unused for long periods
of time.
14. Do not connect an amplifi er output in parallel or series with any other amplifi er’s
output. Do not connect the amplifi er output to any other voltage source, such
as battery, mains source, or power supply, regardless of whether the amplifi er is
turned on or off.
15. Do not run the output of any amplifi er back into another channel‘s input.
16. Refer all servicing to qualifi ed service personnel. Servicing is required when the
apparatus has been damaged in any way such as:
- Power-supply cord or plug is damaged
- Liquid has been spilled into the unit
- An object has fallen into the unit
- The unit has been exposed to rain or moisture
- The unit does not operate normally
- The unit was dropped or the enclosure is damaged
17. Do not remove top or bottom covers. Removal of the cover will expose ha-
zardous voltages. There are no serviceable parts inside and removal may void
the warranty.
18. An experienced user shall always supervise this professional audio equipment,
especially if inexperienced are using the equipment.
