Key features include high and low impedance options, a new 'Double Power Mode', selectable input formats for broader applications, 8 x 140W at 8 Ohm/4 Ohm, 8 x 125W / 40 Ohm on 100V/70V lines, and 4 x 280W in Double Power Mode (8 Ohm/4 Ohm). Technical specs cover output power, voltage gain, input sensitivity, S/N ratio, power consumption, THD+N, frequency response, crosstalk, maximum input level, input impedance, connectors, protection circuits, cooling fan, power requirements, dimensions, and weight.
Using the Yamaha XMV8140 - D is straightforward. First, connect your audio sources to the appropriate analog or digital inputs. For speakers, use the barrier strip output. Make sure to select the right input format according to your application. When using the Double Power Mode, be aware that it will increase the output power. As for power, this amplifier can work with 100V, 120V, 230V - 240V at 50Hz/60Hz. Regarding safety, the amplifier has load and power supply protection circuits. If the heatsink temperature goes above 100 degrees Celsius, it will shut down automatically. Also, keep in mind that the amplifier has a 3 - speed cooling fan, so ensure proper ventilation around it. For maintenance, keep the amplifier clean and free from dust. Check the connections regularly to make sure they are secure. If you notice any unusual noises or performance issues, turn off the amplifier and seek professional help.
