OUTPUT POWER vs. SPEAKER SAFETY
The Cinepro 4K6 MK-4 SE-Gold was designed to create peak sound pressure levels mimicking real life. This is important for
the realistic reproduction of cinematic events. An on-screen gunshot or train wreck can create short-term power bursts of over
1000 watts! The Cinepro 4K6 MK-4 SE-Gold can faithfully reproduce these transients without strain.
Most high quality loudspeakers are designed to accept signals well in excess of their rated power for short duration events
called "peaks". In fact, more loudspeakers are damaged from under powering than overpowering. This is due to the fact that
when a smaller amplifi er runs out of power, and clips, it produces non-musical signals called square waves. These square waves
quickly heat up the voice coils on the speakers, and failure results. The Cinepro 4K6 MK-4 SE-Gold is unlikely to produce
square waves during normal usage, due to its unique photo-optic anti-distortion circuitry.
Some reasonable care must be taken when playing at extremely loud continuous levels. Do not turn up the amplifi er to
uncomfortable sound levels for an extended period of time. This can damage your hearing, as well as put your speakers in
jeopardy. Most speakers will "tell you" when they are being overdriven. The sound gets "raspy" and in extreme overdrive
conditions, the speakers will actual make loud "clacking" noises. Obviously, turn down the volume until these conditions
subside. Used responsibly, and with care, the power capabilities of the Cinepro 4K6 MK-4 SE-Gold will produce real life sound
pressure lev els, and your speakers will bring them into the room.
COOLING
Due to the extended "Class A" operation of this amplifi er, the unit will run warm to the touch at the back heat sinks.
The Cinepro 4K6 MK-4 SE-Gold features our advanced "Whisper Cool" forced air cooling system. Under normal listening
conditions, the rear dual fan pack will operate at a very low speed. If usage causes the amplifi er to get even warmer, the unique
rear dual fan pack will in crease speed to further cool the massive output stage. The fans will reset back to silent operation when
the instrument has cooled itself suffi ciently. This cooling system ensures that your 4K6 MK-4 SE-Gold is always operating at
optimal temperatures.
Do not block the left side inlet fan slots since air must be free to move around the amplifi er. If used in a closed cabinet, internal
heat may build up and cause the amplifi er to shut down temporarily due to overheating. If this occurs, install a small muffi n-
type fan at the top of the cabinet to exhaust the heated air.
It is normal for the fans to cycle during a robust movie viewing experience. The fan noise is low enough that it should not
detract in any way from the soundtrack. In fact, with the fans operating at high speed, the noise level is about one-third as loud
as the average computer fan. But this advanced cooling system will enhance the life of the amplifi er, as well as maintain the
best operating temperature for music and cinematic enjoyment.
PROTECTION LIGHT
On the front panel, directly below the power light is the protection light. The Cinepro 4K6 MK-4 SE-Gold utilizes a fail-safe
protec tion system that will protect your speakers in the event of any internal failure, or a large DC spike occurring at the input
jacks, or excessively high line voltage feeding the amplifi er (over 132 volts in the 120 volt mode, or 264 volts in the 240 volt
mode). If the protection lamp illuminates, and the wall voltage has been verifi ed to be around 120 volts, this indicates an
internal problem with the amplifi er, or the signal feeding it. Power the 4K6 MK-4 SE-Gold down for 2-3 minutes. This allows
the protection circuit to reset. If the lamp still illuminates on power-up, disconnect the signal input leads from the amplifi er.
Again, wait two minutes, and power-up. If the lamp remains lit, please contact the factory.
CLEANING
The front panel may be cleaned with any mild window/surface cleaner. Do not use solvents as these may harm the fi nish.
About once a year, vacuum the air inlet slots on the left side of the amplifi er. Use a soft brush and remove any standing dust
that may have accumulated. Also, vacuum the rear heat sinks to remove any light dust coating that may be present. In dusty
environments, more frequent cleaning may be necessary.
FUSES
There are no fuses in this amplifi er. The front panel power switch doubles as a heavy-duty circuit breaker. All other protection
circuits are electronic, and automatically reset when activated. Do not remove the top cover of the Cinepro 4K6 MK-4 SE-
Gold. There are no user serviceable parts inside.
