FCC INFORMATION (U. S. A. )
1. IMPORTANT NOTICE: DO NOT MODIFY THIS UNIT!
This product, when installed as indicated in the instructions contained in this manual, meets FCC requirements. Modifications not expressly approved by Yamaha may void your authority, granted by the FCC, to use the product.
2. IMPORTANT: When connecting this product to accessories and/or another product use only high quality shielded cables. [. . . ] Make absolutely sure that these intakes are not obstructed.
Front Rear
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
Air intake
Air exhaust
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.
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.
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. )

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).
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.
Hot
Ground
Cold
* 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.
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.
2 Euroblock connectors
These balanced Euroblock connectors are used to connect input signals.
6 SPEAKERS terminals
These 5-way binding posts are used to connect speakers.
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.
7 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.
4 MODE switch
STEREO mode
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.
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.

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.

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.

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.

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. [. . . ] Inrush current: 11A (100V), 13A (120V), 25A (240V)
