Stem Ripper:

8 Channel Audio Recorder

ALM050 Buy Now (In Stock)

The Stem Ripper is a compact 8 channel audio recorder designed for immediate full patch recording without the need for external hardware. Capture all audio stems of a patch with ease.

Patch stems are recorded directly to a micro SD card which can then be easily transferred to a computer to mix, edit or archive patches. Each input is recorded as an individual track in a multichannel date stamped WAV file. Record time is limited only by SD card size. Two additional tracks within the output WAV contain a configurable stereo mix down of the inputs.

The module has large 20Vpp per input headroom with LED clip indication if exceeded.

An optional 2HP ‘Thru’ output expander duplicates the 8 inputs to a row of unbuffered outputs, eliminating the potential need for stacking patch cables at the expense of more case real estate. Also now available is the 'With Mixer' expander which turns the Stem Ripper into a fully featured stereo mixer. 

A suitable 64Gb SD card is included with the unit.
