PLACEMENT

The dissipation of the heat produced by the power MOSFET is a slot way, placed above.

The particular configuration as it takes advantage of the upward convection of hot air, drawing it down over

the device and funnelling it to the upper slots. With this solution it is not necessary to provide a large space

side and top, but it is good that the amplifier remains above a certain free space to allow the air vent slits.

In order to receive commands, in addition, the infrared receiver must not be covered by anything and the

front panel of the amplifier must be well in sight to the remote.

REAL PANEL

The rear panel of the amplifier is divided in two by the heat sink: the left side houses the signal connections

and the right side the power connections.

1. POWER SOCKET

This is a standard IEC recessed plug. Any power cord meeting this standard can be use. If the power cord

supplied with your unit does not fit into your wall outlet, replace it with one that is rated at least 10 A.

2. MAIN POWER SWITCH

This serves to power up and completely shut down the unit. Under normal operating conditions, it should

be left in the ON position, thus supplying power to the control microprocessor.

3. MICROPROCESSOR LINE FUSE (0.5 A)

This fuse protects the power supply of the circuits that control the amplifier's remote control.

4. MAIN LINE FUSE (3.5 A)(7 A for 110 V or 100 V, main line voltage)

This fuse protects the power supply of the audio circuits of the amplifier.

5. L1 INPUT

Line Input Unbalanced, RCA pin jack golden, selectable by pressing the L1 button on the remote control.

You can connect any equipment with a rated output greater than 400 mV.

Only MK 2280 and MK 2225 balanced line input XLR connectors.

6. L2 INPUT

Unbalanced line input, selected by pressing the L2 button on the remote control. Accepts any source that

has a nominal output level ranging from 400 mV to 6 V.

7. L3 INPUT

Unbalanced line input, selected by pressing the L3 button on the remote control. Accepts any source that

has a nominal output level ranging from 400 mV to 6 V.

8. L4 INPUT

Unbalanced line input, selected by pressing the L4 button on the remote control. Accepts any source that

has a nominal level ranging from 400 mV to 6 V.

9. L5 INPUT

Unbalanced line input, selected by pressing the L5 button on the remote control. Accepts any source that

has a nominal level ranging from 400 mV to 6 V.

10. RIGHT SPEAKER OUTPUT

Power output, with gold plated terminal. These terminals accept stripped wire up to 6 mm

mm banana jack. Connect the "+" terminal to the positive binding post of the right speaker and the "-"

terminal to the negative binding post of the right speaker.

11. LEFT SPEAKER OUTPUT

Power output, with gold plated terminal. These terminal accept stripped wire up to 6 mm

mm banana jack. Connect the "+" terminal to the positive binding post of the left speaker and the "-"

terminal to the negative binding post of the left speaker.

12. REMOTE CONTROL

Digital output, to be used only to control an additional add-on GALACTRON. When this output is not

in use, the plug inserted at the factory must be left in place; this plug should only be removed to

connect the control cable to a GALACTRON power amplifier.

13. FRONT PANEL

On the front panel there are 3 controls, Source Selection, Volume, Power On - Off.
