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 These 5-way binding posts are used to connect speakers. 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. 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. 5 7 6 6 1 8 32 4 13 2 4 * The illustration shows model XM4180. Ground Cold Hot 5 8 XM4180/XM4080/XH200 Owner’s Manual . 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 Speaker Speaker Speaker Input signal Connect B and C * The illustration shows model XM4180. + – + – Speaker Speaker Input signal Connect B and C * The illustration shows model XM4180. 6 . 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 ...
