Yamaha’s XMV series of multi-channel power amplifiers offer a comprehensive line-up to power your sound solution. XMV amps combine Class-D efficiency and features that specifically benefit commercial installation sound systems. When used in systems with MTX/MRX series processors, XMV amps offer additional advantages, particularly when paired with the MTX-MRX Editor software application. The XMV4140 has YDIF digital audio format, ensuring easy setup with the use of Ethernet.
Installed sound applications often require both high and low impedance connectivity in the same venue: with an XMV amplifier, you no longer need a separate amp or dedicated transformer. The XMV4140 has a high-impedance mode (70V/100V line) and a low-impedance mode (4Ω/8Ω) which can operate simultaneously. XMV power amplifiers also support both 70V and 100V operation for every pair of channels, selected via dip switches on the rear panel.
Get twice the output power of selected channels in Double Power Mode. Although this reduces the number of channels you can use by half, it means that speakers with varying output capacities can be powered simultaneously by the same amplifier so your system can be even more flexible.
An innovative, patent-pending circuit improves the already highly efficient Class D circuit topology in the XMV by automatically switching the circuit to match the corresponding output voltage. This keeps the amp running at its most efficient even when switching from high impedance to low impedance operation. Power Factor Correction is also present to ensure harmonic control and dramatically decrease the amount of current draw while maintaining output power.
Automatic protective features and specific redundant functions can be enabled to keep the XMV4140 safe in less than ideal circumstances. Backup Mode is used to detect an incoming pilot tone from the digital input and automatically switch to analog input when the pilot tone is disrupted. Override Mode switches input sources for a channel without interrupting sound when voice input from the analog input is detected.
