Add 8 affordable, pro-quality preamps to your DAW.

The EP84 is the latest multichannel microphone preamplifier from SM Pro Audio. Packed with quality features and connectivity options, this sturdy 2RU rack-mountable unit is designed to provide studio users with 8 channels of clean and accurate microphone preamplification. The EP84 is an excellent front end for computer audio systems, stand-alone hard disk recorders, or just about any other analog or digital workstation.

With all the functionality of a top line preamplifier, the EP84 features independent variable gain control, -20dB pad, phase reverse, low cut filters, 48v Phantom power, and insert points on each of the eight (8) channels.

Each mic-pre provides some 60dB of gain with a massive 23db of maximum output.
Eight (8) ADAT format channel outputs can be added to the EP84 via installation of the optional PR8IIA ADAT output module. With this simple user installed option, the EP84 integrates superbly into today's digital studio environments without a hitch. Great for connection to the latest ADAT compatible audio interfaces, the EP84 expands your recording possibilities - you can even mic up the whole band!

Note: The analog outputs (both +4dB XLR & -10dB TS) and the digital ADAT ouput (when fitted with the PR8IIA output module) operate simultaneously.

best multichannel out there

Comments about SM Pro Audio EP-84 Multichannel Microphone Preamplifier:

While working on our new album we ran into the trouble of not enough inputs and we needed a good pre amp multichannel. So my friend that owns his own studio suggested the sm pro audio EP84. After I bought two of them I had them out of the box and using them within the hour. I hooks up perfect to my 1814 I use the bottom with the direct outs and the top one w/ my adat and word clock the options are endless and the sound quality un matche and it's not going to burn your a** off when you pay for it.

Comments about SM Pro Audio EP-84 Multichannel Microphone Preamplifier:

I am using this in front of a PreSonus StudioLive 16.0.2 and it is AWESOME! I plug guitars, mics, electronic drum set, and digi tech guitar multi effects.
It is very clean. No white noise or buzzing at all.

For the 8 channels and the XLR outputs which most don't have, this is a steal.
