① POWER/STANDBY switch and indicator

This is the main POWER switch. Press to turn on the amplifier. Press it again to turn off. The POWER indicator lights up when the amplifier it turned on. STANDBY operation can only be set from an external device, connected to the REMOTE terminal. When STANDBY is on, the indicator is lit in orange.

② PROTECT/MUTE indicator

When the protection system is active, the PROTECT indicator lights up and the speakers are automatically disconnected from the amplifier's outputs. The protection system activates in the following situations:

When the amplifier is turned on

The protection system activates for approximately three seconds when the amplifier is turned on. After three seconds, the protection system deactivates automatically and the amplifier is ready for normal operation.

If a DC voltage is detected at the amplifier's outputs

The protection system activates if a DC voltage is detected at the amplifier's outputs. Once the DC voltage problem is corrected, the protection system deactivates automatically and the amplifier is ready for normal operation.

If the amplifier overheats

When overheating occurs, the PROTECT/MUTE indicator lights. You should immediately turn off the amplifier and allow it time to cool down. See the Precautions section of this Owner's Manual for ways to prevent the amplifier from overheating.

③ CLIP/LIMIT indicator

A channel's CLIP indicator lights up when its output distortion exceeds 1% (i.e., clipping). Output signal clipping is typically caused by excessive input signal levels. When this happens, the limiter is engaged automatically.

④ SIGNAL indicator

A channel's SIGNAL indicator lights up when its output exceeds a certain amount (2V rms on the XM4180/ XM4080, 4V rms on the XH200.)

⑤ VOLUME controls

The channel volume controls have click detents for the settings, and each channel can be set over a range of - dB to 0dB . On the XM4180 and XM4080, when the amplifier is set to bridged mode, only the first volume control on each channel pair is used (i.e., for the A/B pair, channel A is active, and for the C/D pair, channel C is active).

⑥ Air intakes

The amplifier has a forced-air cooling fan that takes in air from the front and exhausts it from the rear. Make absolutely sure that these intakes are not obstructed.

Security cover

If you want to keep the volume settings from being modified, attach the included security cover using the screw holes shown below, so that the volume controls are inaccessible.

* The illustration shows model XM4180.

① XLR inputs connectors

These balanced XLR-3-31 type connectors are used to connect input signals.

The pins are wired as shown below (IEC 60268).

• In bridged mode, only the first channel in the pair is active; i.e., channel A of pair A/B, and channel C of pair C/D. Make sure not to input an audio signal to an inactive input terminal.

② Euroblock connectors

These balanced Euroblock connectors are used to connect input signals.

③ HPF switches

These switches are used to turn on and off the HPF (High Pass Filter) for channels A-B or C-D. When this is set to 20Hz or 55Hz , frequencies below the respective settings are filtered using a 12 dB/octave high pass filter.

④ MODE switch

STEREO mode

In STEREO mode, channels A, B, C and D are completely independent.

PARALLEL mode

In PARALLEL mode, the channel A input signal is sent both to the channel A power amp and the channel B power amp. In this case, loads are automatically connected between the A and B input terminals. (The same applies to the C and D input terminals.)

By sending the signal from channels A/B to C/D you can use the unit as a four-channel mono amplifier.

BRIDGED mode

In BRIDGED mode, channels A and B operate simultaneously, functioning as a single mono amplifier.

(The same applies to the C and D.)

Note: When in PARALLEL and BRIDGED modes, input terminals A-B and C-D are shorted automatically. Make sure not to input an audio signal to an inactive input terminal.

⑤ MONITOR/REMOTE terminals

This terminal is used to connect the external device for monitoring or remote control. Refer to "MONITOR/REMOTE PIN layout" on page 14.

⑥ SPEAKERS terminals

⑧ AC IN

Connect one plug of the included AC cable to this inlet. Connect the other plug of the AC cable to an AC outlet that meets the power supply conditions printed on the label at the top of the unit.

- Using as a four-channel mono amplifier with a mono input (XM4180/XM4080)

By connecting input terminals B and C with a proper cable, and setting both mode switches for A/B and C/D to PARALLEL, you can use the unit as a four-channel mono amplifier.

The volume controls on the front panel (A to D) let you control the volume of each channel independently.

Note In this case, the loads for A and B or C and D are connected in the amplifier. Make sure not to input any signal to the D terminal.

* The illustration shows model XM4180.

- Using as a two-channel amplifier with a mono input for high-power applications (XM4180/XM4080)

By connecting input terminals B and C with a proper cable, and setting both mode switches for A/B and C/D to BRIDGE, you can use the unit as a two-channel high-power mono amplifier.

Note In this case, the loads for A and B or C and D are connected in the amplifier. Make sure not to input any signal to the D terminal.

* The illustration shows model XM4180.

- Speaker connections (XM4180/XM4080)

Speakers can be connected to the amplifier in two ways, as shown below. Note that speaker impedance will vary according to the connection method and the number of speakers. Please be sure that your speaker's impedance is not less than the relevant minimum value indicated below.

Connection configurations for STEREO and PARALLEL modes

* The illustration shows model XM4180.

When connecting high-impedance speakers in parallel (XM4180 only)

XM4180 enables you to connect in parallel fashion multiple high-impedance speakers that support 70V line output. The number of speakers that can be connected varies depending on the rated input of the speakers. The XM4180 can be connected to speakers with a total rated input of up to 300 W. For example, if you connect ten speakers with a rated input of 5 W (50 W), ten speakers with a rated input of 10 W (100 W) and ten speakers with a rated input of 15 W (150 W), the amplifier can be used with a total rated speaker input of 300 W as shown below:

CAUTION

Be sure to use speakers that support the XM4180's line-out voltage of 70 V.

* The illustration shows model XM4180.

Rear Panel (XH200)

① Euroblock connectors

These balanced Euroblock connectors are used to connect input signals.

② HPF switches

These switches are used to set the cutoff frequency of the HPF (High Pass Filter) for each channel. Frequencies below 40Hz or 80Hz are filtered using a 12dB octave high pass filter.

• When the amplifier is set to 40Hz , make sure that the speaker transformer is capable of sufficiently handling low frequency signals.

CAUTION

Be careful when inputting low frequency signals; excessive levels at low frequencies may cause damage to the speaker, speaker transformer or to the amplifier itself.

③ Output voltage switch

This switch is used to change the output voltage between 70V and 100V.

Hot ,Cold

Refer to "Speaker connections (XH200)" on page 10 for more information on the impedance of speaker systems that can be connected to these terminals.

GND terminal

If you are having a problem with hum or noise, use this terminal to connect to ground (earth) or to connect to the chassis of a mixer, preamp, or other device in your system.

⑦ AC IN

• Connect one plug of the included AC cable to this inlet.
• Connect the other plug of the AC cable to an AC outlet that meets the power supply conditions printed on the label at the top of the unit.

Speaker connections (XH200)

The XH200 enables you to connect in parallel fashion multiple high-impedance speakers that support 70V or 100V line output. The number of speakers that can be connected varies depending on the speaker's rated input. You can connect speakers with a total rated input per channel of up to 200 W.

For example, if you are using speakers with a rated input of 10W , you can connect up to twenty speakers. If you are using speakers with a rated input of 20W , you can connect up to ten speakers

You may also connect speakers with different rated inputs to different channels or connect speakers with different rated input to the same channel, as shown below:

Total rated input of speakers : 200W

CAUTION

Be sure to use speakers that support the XH200's line-out voltage of 70V or 100V.

CAUTION

You cannot connect a low-impedance speaker directly to the XH200. In this case, be sure to use a speaker transformer (such as the Yamaha ST15). Follow the instruction guide that came with the speaker transformer to avoid excessive loads.

Using a Euroblock connector

Cable preparation

• To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration, and use stranded wire to make connections. With a Euroblock connection, the stranded wire may be prone to breakage because of metal fatigue due to the weight of the cable or due to vibration. When rack-mounting your equipment, use a lacing bar when possible to bundle and fasten the cables.

• If cables will be frequently connected and disconnected, as in the case of a portable installation, we recommend that you use ferrules with insulation sleeves. Use a ferrule whose conductor portion has an external diameter of 1.6 mm or less, and a length of approximately 7 mm (such as the AI0, 5-6WH made by the Phoenix Contact corporation).

CAUTION

If you use stranded wire, do not tin (plate with solder) the exposed end.

1 If the wire insertion ports are closed, turn the screws on top of the connector counterclockwise to open the ports.
2 Insert the wires into the appropriate ports, following the indication of the pole on the input terminal, turn the screws on top of the connector clockwise to fix the wires.
3 Attach the Euroblock connector to the input terminal on the unit.

Speaker Connection

1 Turn off the POWER switch.
2 Remove the cover attachment screws and remove the protective cover from the speaker terminals.

3 Remove about 15mm of insulation from the end of each speaker cable.
4 When using 5-way binding posts (XM4180, XM4080) Pass the bare wire through the holes in the appropriate speaker terminals. Tighten the terminals to securely clamp the wires. Refer to 9 page for speaker polarities. Be sure that the bare wire ends do not jut out from the terminals and touch the chassis.

When using barrier strip terminals (XH200)

Wrap the wire around the terminal as shown in the illustration, and tighten the screw to securely clamp the wire. Refer to 10 page for speaker polarities.

Be sure that the bare wire ends do not jut out from the terminal and touch the chassis.

5 Reattach the protective cover over the speaker terminals.

Troubleshooting

The following table lists the main causes of abnormal operation and the corrective measures required as well as the protective circuit operation in each case.

Indicator	Possible Cause	Remedy	Protection Circuit
CLIP/LIMIT indicator lights up	There is a short at the amplifier's speaker outputs, the speaker's inputs, or in the wiring.	Locate and remove the short.	The PC limiter circuit activates to protect the power transistors.
	The impedance of the connected speaker is too low.	Check the impedance rating of the connected speaker and make sure that it conforms to the impedance indicated at the speaker terminals on the amplifier.
PROTECT/MUTE indicator lights up	The temperature of amplifier is too high.	Let the amplifier cool and check that ventilation around the amplifier is appropriate for operation, as suggested in the Precautions section.	The thermal protection circuit activates to protect the power transistors.
	A DC voltage of ±2 V or greater was detected in the amplifier's output circuit.	Consult your dealer or a Yamaha service center.	The output relay activates to protect the speaker system.
