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 6 4 2 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.
