SM Pro Audio releases HP6E enhanced multichannel headphone amp
February 10, 2008
Melbourne, Australia-based SM Pro Audio used the recent NAMM show to showcase its new HP6E multichannel headphone amplifier. The HP6E is a high-quality, powerful, flexible and reliable six-channel headphone amplifier with four independent stereo inputs housed in a sturdy 1RU metal chassis.
The HP6E boasts a variety of improvements over the original HP6, including improved frequency response, more power, digital control of input selection and a fifth mix input. Built-in flash memory has also been added to allow for last state memory recall of the input selection for each channel.
The unit’s 10 inputs are set up as five TRS stereo jacks. Frequency response is a full 20Hz–20KHz with total harmonic distortion of less than 0.02 percent. Output is 600mW per channel at 32ohms with mix control for each output amplifier. An auto-sensing power supply ensures safe operation.
The SM Pro HP6E allows any of four available audio input source signals to be routed to any of its six Class A headphone amps. An additional fifth stereo signal can also be mixed into each individual headphone channel. This allows for endless application support including studio monitoring, live monitoring, in-ear individual mixing, signal distribution and more. For more information, visit
