Imprimer la page7. BALANCE
Press this Key to attenuate the level of the right of the right or left channel by one step, shifting the
balance of the amplifier. To attenuate by another step, release the key and press again.
10. MUTE
Press this Key to lower the volume by 20 dB.
To restore the volume to its initial level, press the key again.
11. HEADPHONES
This function is not implemented in the MK 2240 and MK 2245 amplifier; pressing this Key will not
have any effects.
12. PROG.
Press this Key to initiate the microprocessor programming sequence.
To restore the microprocessor to normal operating mode, press the key again.
13. VOL.PR.1
Press this Key to automatically adjust the volume to the first preset value. The Key is also used in
programming mode to memorise the desired volume level.
14. VOL.PR.2
Press this Key to automatically adjust the volume to the second preset value. The Key is also used in
programming mode to memorise the desired volume level.
15. VOL.PR.3
Press this Key to automatically adjust the volume to the third preset value. The Key is also used in
programming mode to memorise the desired volume level.
16. HEAD PR.
This function is not implemented on the MK 2240 and MK 2245 amplifiers.
17. STAN-BY
Press this Key to deactivate the amplifier, placing it in STAND-BY mode. In this condition, the control
microprocessor is active whereas the amplifier itself is inactive. To activate the amplifier, press any of the
input selection buttons 1 to 4.
18. DIMMER
Press this Key to enable an external dimmer, used to vary the light level in the room.
(OPTIONAL DM 2004).
19. BATTERY HOLDER
The remote control requires four AAA batteries. When the batteries are low, the remote control will not
function.
CONNECTING THE PROGRAM SOURCES
All inputs have a nominal sensitivity of 400 mV, allowing to connect any audio source without risking
saturation or excessive noise. The sufficiently high input impedance protects the output stages of the audio
sources from overload. Moreover, the presence of an isolator stage on the tape output guarantees that the load
seen by the sources is not influenced by the presence or absence of the recorder, and at the same time,
provides a sufficiently low impedance at the output so as not be affected by the characteristics of the records
interface.
Check that the audio source and amplifier are correctly matched, right channel with right channel and left
channel with left channel. Without here delving into the audio characteristics of the interconnects, always use
cables with gold or rhodium plated terminals to minimise the formation of surface oxidation, which greatly
degrades the system sound quality.
Similarly, before making the connection, carefully remove all traces of grease and oxidation from the
amplifier terminals and cable end-connectors using alcohol or other suitable cleaning fluid. Remember that
merely touching the connectors with your fingers will deposit an isolating film of oil.
CONNECTING THE "REMOTE CONTROL" OUTPUT
This output must be used only when the amplifier is operated together with a GALACTRON power
amplifiers in bi-amp configuration. The "remote control" output comes factory equipped with a plastic plug,
this plug must remain in place unless the outlet is connected to the same name input in the rear panel of a
GALACTRON power amplifier. Before to physically connect together the units with a standard RCA
shielded cable, please check that both the power switches are in the Off position. Turning on the units to the
"Stand-By" mode for the first time, it is mandatory to operate first the power switch of the integrated
amplifier (master) and later on the power amplifier's switch (slave). Now being in the stand-by mode, a
turning-on command from the master integrated amplifier remote control will light up also the slave power
amplifier. This routine must be repeated when one or both the units have been turned off by the power switch
or disconnected from the AC main supply.
