Fostex VM88 User Manual

Model
Introduction
Thank you very much for purchasing the Fostex VM88.
Please read the following to get the most satisfaction from your purchase, and to
learn important information about safety precautions when using Fostex prod-
ucts.
The VM88 digital mixer does all internal signal processing digitally.
The input features 8 analog channels, of which 4 channels (XLR or PHONE) are for
microphones; digital inputs (S/P DIF or ADAT) via optical connection are provided.
For outputs, an optical digital output (S/P DIF or ADAT) in addition to stereo out
(balanced/unbalanced), headphone out, AUX send/out and monitor outs in analog
are also provided. An insert function is featured in channels 1 - 4 for more
flexibility during mixing.
In addition to each input channel, an three band EQ is also provided for the
master output. The VM88 also incorporates high performance DSP multi-effects
on two channels that operate by A.S.P. (Fostex Advanced Signal Processing Tech-
nology*) exclusively developed by Fostex. This allows a wide range of equalizing
and effects processing. All settings, including mix and effects settings, are stored
in scene memory, and a desired scene memory can be recalled instantaneously.
Although small and lightweight, the VM88 is a high performance unit. Please
read this manual carefully before operation to understand all functions of the
VM88.
* See page 24 for more details on the A.S.P. (Fostex Advanced Signal Processing Technology).
