SM Pro Audio has exhibited several products at this NAMM show : the new HP6E multi-channel headphone amplifier, the PR8DS remote controllable multi-channel microphone preamplifier and their iNano passive volume control.

The HP6E is a high-quality, powerful, flexible, and reliable six (6) channel headphone amplifier housed in a sturdy 1RU 19" standard rack-mountable metal chassis.

Features :

-10 TRS inputs, 5 stereo channels
- 6 class A headphone amplifiers
- Auto sensing switch mode power supply
- Built in flash memory for last state memory recall
- Mix control for each amplifier output
- Nominal output @ 32Ohm 600mw per channel
- Frequency response @100mw output 20Hz-20kHz +- 0.3 dB
- THD @300mw less then 0.02%


The PR8DS is a professional multi-channel pre-amp designed for applications where remote control is desired. Based on the PR8E, the PR8DS features 8 channels of high-quality balanced microphone pre-amplification with independent 48v phantom power and peak led indicators. Analog connectivity is provided by way of 8 x balanced/unbalanced combo connector inputs on the front panel and 8 x balanced analog outputs (D-sub 25) on the rear.

The system is controlled via the standard RS232 interface implemented on the rear panel. RS232 command information is provided in the manual to allow user programming of compatible RS232 command devices. Independent remote control of channel gain and phantom power is provided in addition to the ability to receive peak indicator information feedback to the remote control device.

SM Pro Audio's own RCA V1.0 software (Remote control application, Windows only) ships with the unit and allows full control and peak feedback information across all channels. A stand-alone hardware RS232 controller is planned for release in Q3 2008.


The iNano is a compact pure passive volume control, it allows precise level adjustment to analog audio source material. Featuring balanced combo XLR/TRS and 3.5mm input jacks and TRS and 3.5mm outputs, mute switch, and a good sized rotary volume encoder, the iNano is a great way to passively attenuate stereo signals from computers, soundcards, CD players, pre-amps, and mixers. The iNano is set for release at a list price of USD $69.00
