extremely
extremely high-power capability of this amplifi er, special consideration must be given to AC power and cooling
airfl ow. Please read the following information carefully to ensure reliable, trouble-free operation of this instrument.
Your Cinepro 4K6 MK-4 SE-Gold utilizes a combination of convection and forced-air cooling. Under most circumstances, and with
adequate ventilation in the rear of the amplifi er, the dual external fan pack will activate when playing the amplifi er at high volume
levels for an extended period of time. The dual fan pack is a special unit, combining high effi ciency with very quiet operation.
A slight "rushing" sound may be noticed during use. The fans will automatically switch to low speed silent operation when the
amplifi er has cooled down suffi ciently. This system maintains the amplifi er circuitry at the optimum operating temperature.
The Cinepro 4K6 MK-4 SE-Gold may be mounted in a cabinet or on a shelf, provided that there are at least two inches of space
behind the heat sinks, and three inches of clear space above the amplifi er. If the amplifi er is installed in an enclosed shelf with
an enclosed back (not recommended for heavy-duty use), allow six inches of space above the amplifi er if possible. The front
panel is standard EIA 19" rack width. It is designed to be rack mounted by its faceplate if desired.
To power this instrument, plug the female IEC end of the power cord into the male panel-mounted IEC connector, and plug
the standard male end of the power cord into a three-prong 120 volt grounded outlet, directly into the wall. Never plug into
the "switched outlets" on any piece of equipment. Do not use power conditioners, or multiple outlet power strips, they will
starve the amplifi er of its tremendous power needs, unless of heavy-duty type such as Cinepro Inc.'s New Reference 240V
30A regulated power conditioner. If you live in active lightning areas, we recommend a heavy-duty surge protector. The unit is
designed to operate satisfactorily from a standard 120 volt, 15 amp service; however, we recommend at least a 20 amp service
whenever possible. If a 30 amp, 120 volt service is available, that will provide the most dynamic sound, and the best bass
response. For permanent installations, and heavy-duty commercial use, we highly recommend 240 volt, 20 amp wiring. The
unit is easily converted to 240 volt operation by any qualifi ed electronic service facility. Please call the factory if you would
like voltage conversion instructions, or have any other questions regarding AC power requirements.
FRONT PANEL
To achieve absolute clarity in sound reproduction, no front panel volume controls are used in this instrument.
Across the top of the front panel are six green and red LEDs. The green LEDs are the signal indicators. They will fl ash as
each channel is reproducing a signal. This is handy in troubleshooting a complex home theater system, and to verify proper
operation of the power amplifi er. In the event any two front panel green LEDs fail to light when a signal is known to be
present at the inputs, this could indicate internal thermal protection has been initiated for those channels. The sound will come
on again after about 1 minute. Additional airfl ow must be supplied to the rear of the amplifi er. Please consult the factory for
recommendations.
The red LEDs are clipping indicators. At very high volume levels it is normal for these indicators to fl ash occasionally. This
means that full power is being generated for a dynamic peak. If the red light comes on for more than about a half a second
continuously, automatic clipping protection is engaged, protecting your speakers from hard clipping. The volume should be
reduced to just below this point. Please note that if the red LEDs seem to come on at lower than maximum sound pressure
levels, this may indicate that the AC power supplying the unit is being drained low. Stiffer AC wiring, or 240 volt connection
may be required to fully enjoy the power capabilities of the 4K6 MK-4 SE-Gold.
No internal fuses are used in the Cinepro 4K6 MK-4 SE-Gold. The front panel power switch is actually a heavy-duty circuit
breaker. Once activated, there is a built-in 3 second delay to allow all internal circuits to stabilize. The power LED indicates the
amplifi er has performed its internal self-check and is ready to go.
BREAK-IN PERIOD
Although the 4K6 MK-4 SE-Gold will sound incredible right out of the box, the sound will dramatically improve over the fi rst
100 hours of use. The most noticeable improvement will occur after 25 hours. You should notice the sound gradually becoming
smoother, more musical, and more dynamic during the break-in period.
For optimum sound quality, we suggest that you turn the amplifi er on about 15 minutes prior to serious listening (most
amplifi ers perform best when they are fully warmed up). Some people actually prefer to leave the power amplifi er on 24 hours
a day; the unit is designed to allow for this. When no music is playing, the amplifi er draws about 140 watts.
You may notice a slight thump in your speakers as the amplifi er is turned off. This is normal, and due to the fact that we do
not use speaker relays in our amplifi ers. Speaker relays are prone to failure, and slightly degrade the sound. The power-down
"thump" you may hear in no way endangers your loudspeakers.
