The unit will enter standby mode in one of the following events:

•If the unit is powered on but not operated for eight hours while the auto power standby function is turned on, or

•If you turn off the power to the device that is connected to this unit’s TRIGGER IN jack.

For more information, refer to “G AUTO POWER STANDBY switch” in the “Rear panel” section (page 9) and to “Trigger connections” (page 13).

Note

After you turn on the unit, it will take a few seconds before the unit can reproduce sound.

NOTICE

If you plan not to use the unit for an extended period of time, be sure to unplug the power cord from the AC outlet. Even when the STANDBY/ON/OFF (Power) switch is turned off (the power indicator is dark), a minimal amount of electric current is still flowing to the unit.

B. SPEAKERS selector

Balanced and unbalanced connections

This unit features balanced input jacks (BAL) and unbalanced input jacks (LINE).

NOTICE

Do not use balanced and unbalanced connections between two components simultaneously.. Doing so would create a ground loop that could generate static and noise..

Balanced connection

A balanced connection is a great advantage against external noise. For a balanced connection, use a cable with male XLR connectors. When connecting a cable, be sure to align the pins on the connector with the holes on the jack, and then insert the connector into the jack until you hear a click. To remove the cable, while pressing and holding down the lever on the BAL jack, pull out the male XLR connector from the jack.

Pin #2

Pin #3

Pin #1

When making a balanced connection, you must set the polarity correctly. To set the polarity, use the PHASE selector on the rear panel.

Connections

This section explains how to connect the unit to a preamplifier and speakers.

CAUTION

Turn off the power to all components before making any connections..

NOTICE

Before you connect external components, read and follow the instruction manuals for those components.. Otherwise, this unit or external components might malfunction..

Note

•All connections must be correct: L (left) to L, R (right) to R, “+” to “+”, and “−” to “−”.. If the connections are faulty, no sound will be heard from the speakers.. Also, if the polarity of the speaker connections is incorrect, the sound will be unnatural and lack bass..

•Because this power amplifier is of the floating balanced type, the following types of connections are not possible..

-- Connecting between two “+” (or two “−”) terminals of the left and right channels (Fig.. 1)..

-- Connecting each “−” terminal of the unit’s left and right channels to the opposite channel speakers (cross connection, Fig.. 2)..

-- Connecting the left/right channel “−” terminals (or accidentally allowing them to come in contact) with the metal part of the rear panel of this unit..

Connecting speaker cables

Using standard speaker cables

1	Remove approximately 10 mm (0.4 in) of
	insulation from the end of each speaker

cable, and twist the exposed wires together tightly to prevent short circuits.

10 mm (0.4 in)

2	Unscrew the knob on each SPEAKERS
	terminal, and then insert the bare wire into

the side hole on the terminal.

Diameter of the speaker cable wire hole: 6.0 mm (0.24 in)

3 Tighten the knob.

CAUTION

•Do not loosen the knob excessively.. Otherwise, the knob might come off and a child might swallow it accidentally..

•To reduce the risk of electric shock, do not touch the SPEAKERS terminals while the power to the unit is on..

NOTICE

If the SPEAKERS terminals come into contact with a metallic rack, a short circuit might occur, resulting in damage to this unit.. When installing the unit in a rack, maintain a sufficient clearance to prevent the SPEAKERS terminals from coming into contact with the rack..

16

Using banana plug cables

First, tighten the knob, and then insert the banana plug into the head of the knob.

Diameter of the banana plug hole: 5.5 mm (0.22 in)

Using Y-shaped lug cables

1	Unscrew the knob, and then sandwich the
	Y-shaped lug between the ring part and

base of the terminal.

Thickness of the

terminal core: 5.0 mm (0.20 in)

To configure a bi-amp stereo system, you need two

M-5000 units.

The M-5000 features two built-in amplifiers. Each of these amps is connected to the mid/high-frequency speaker driver (tweeter) and the low-frequency driver (woofer) on the speaker of the corresponding channel. You need to use speakers that feature two sets of terminals (total of four) that allow each speaker to be split into two sections (low-frequency and mid/high-frequency ranges). Bi-amping speakers can prevent the back flush of

EMF (electromotive force) generated by the woofer from affecting the signal, resulting in improved sound quality in some cases.

Connect the input source to the L-channel input jacks on both M-5000 units.
