The extremely compact SM Pro Audio XPH4 Headphone Amp is conveniently powered with a DC adapter (optional accessory, not included), and housed in a hardened steel chassis. This robust little beast boasts 4 high-powered independently controllable headphone amplifiers.

The XPH4 headphone amp's handy stereo/mono switch is available as required. If you've ever wanted the band to listen to the mix through headphones but there were none left, then you'll understand the need for a multi-channel headphone amplifier, and the SM Pro Audio XPH4 makes a wise choice.
