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. Cable/s supplied with this product MUST be used. Follow all installation instructions.
PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING * Please keep this manual in a safe place for future reference. WARNING Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following: Power supply/Power cord Water warning • Only use the voltage specified as correct for the device.
Handling caution • When turning on the AC power in your audio system, always turn on the device LAST, to avoid speaker damage. When turning the power off, the device should be turned off FIRST for the same reason. • Do not insert your fingers or hands in any gaps or openings on the device (vents, etc.). • Do not use the device for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss.
Introduction Thank you for purchasing a Yamaha XM4180, XM4080 or XH200 Power Amplifier. These power amplifiers were developed from Yamaha’s wealth of experience in building PA equipment and its tradition of careful attention to every detail of circuit design. These power amplifiers feature high power and superb quality together with superior reliability and stability, guaranteeing the highest possible audio performance.
Controls and Functions ■ Front Panel 4 32 1 6 5 * The illustration shows model XM4180. 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.
■ Rear Panel (XM4180/XM4080) 13 2 13 4 2 6 5 4 6 7 8 * The illustration shows model XM4180. 1 XLR inputs connectors BRIDGED mode These balanced XLR-3-31 type connectors are used to connect input signals. The pins are wired as shown below (IEC 60268). Hot Ground 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.
● 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.
● 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.
■ Rear Panel (XH200) 2 1 4 3 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 12 dB/ octave high pass filter. 6 5 7 7 AC IN Connect one plug of the included AC cable to this inlet.
Connection 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: ■ 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.
■ Speaker Connection 1 Turn off the POWER switch. 2 Remove the cover attachment screws and remove the protective cover from the speaker terminals. 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. Screw 3 Remove about 15 mm of insulation from the end of each speaker cable.
