Eight Channel Digital Mixer with DSP Effects
Introduction
Thank you very much for purchasing the Fostex VM08.
The VM08 digital mini-mixer does all internal signal processing digitally.
The input section consists of eight analog input channels including four for
microphones. The output section, in addition to normal analog outputs such
as two channel stereo and a headphone output, also has S/P DIF digital optical output with a 44.1 kHz sampling frequency: and 20 bit quantization.
The internal buss is two channel stereo L/R, plus an independent Effects buss
(1, 2) and an AUX buss (1, 2).
In addition to each input channel, an EQ is also provided for the master output. The VM08 also incorporates high performance DSP multi-effects on two
channels that operate by A.S.P. (Fostex Advanced Signal Processing Technology*) 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 VM08 is a high performance
unit. Please read this manual carefully before operation to understand all
functions of the VM08.
* See page 18 for more details on the A.S.P. (Fostex Advanced Signal Processing Technology).

Model VM08 Owner’s Manual
Before Operation (IMPORTANT Be sure to read below before first using your VM08.)
* Remove the insulation paper
The VM08 uses a memory back up battery inside. You
will find a piece of insulation paper attached to avoid
current dissipation. When using the VM08 for the first time,
turn ON the power and then remove the insulation paper. The
insulation paper is easily removed by pulling it in direction of arrow as shown at right.
* Caution when powering on
There is no power switch in VM08.
Power is switched ON/OFF simply by plugging and
unplugging the VM08’s AC adaptor plug.
Be sure to switch off power to the monitor amplifier connected to the VM08 output or fully retard
the input level controls to prevent damage to connected speakers when
switching power ON/OFF in this
manner.

< Caution >
If the VM08 is not to be used for a long time, be sure
to unplug the AC adaptor from the wall outlet.
* Reset of VM08
It is possible for the computer to malfunction at power ON/OFF or by electro induction noise from lightning. In this happens, switch the power ON/OFF to the VM08 several times. If it does not return to normal
operation, press the rear panel [RESET] switch with a slender ball point pen or similar tool. This returns all
settings to the initial figures setup at shipping from the plant. This procedure can be used to clear all
stored scene memories.
<Please remember this!>
If reset is executed with the INPUT and MASTER raised simultaneous with start up of this unit, the
LEVEL ADJUST key/FADER ADJUST key will blink. This indicates that the VM08 has entered the
Level Adjust Mode/Fader Adjust Mode because of the difference between present fader position
and the fader position at start up following reset. To exit from this mode, retard all faders to the
[MIN] position, and the key blinking will stop.
* Internal battery for the memory back up
The internal battery has a life expectancy of about two years.
When the battery runs low and its voltage falls below a certain level, the warning message "BattEmpty" will appear in
the display. If you continue to use the unit an old battery,
your stored scene memories will be lost when the power is
turned off. Do not try to replace the battery yourself as there are
no user-serviceable parts inside. Please ask your Fostex distributor or an authorized service station to do the job.
<Please remember this!>
There is an automatic internal battery voltage check function in the VM08.
Refer to [Setup mode] on page 27.

1) ST.OUT L, R jack
These are unbalanced phone jacks where an external monitor (amplifier+ speaker) or analog master recorder can be connected. The standard output level is -10dBV.
2) INPUT 1 ~ 4 jacks
These are unbalanced phone jacks for microphones and sound sources such as a guitar. TRIM knobs are
provided for each jack by so input levels can be adjusted to match the sound source, from microphone
input to line level signals.
3) INPUT 5/6 (INPUT 7/8) jacks
TRS type phone jacks for connecting line level sound sources.
As shown in the schematic, both stereo and mono output sound sources can be connected. For either type
signals, the input mode can be selected using the VM08’s setup mode. Refer to [Setup mode] on page 27
for setup of the input mode. Refer to next page for details in preparing and wiring the TRS phone plug.
The standard input level is -6dBV.
4) AUX SEND 1/2 jack
TRS type phone jacks where external effects and mixers can be connected. Two channels, namely, AUX
SEND 1 and 2 are output here. One or two external units can be connected. See the next page for details
in preparing and wiring a TRS phone plug. The standard output level is -10dBV.

Model VM08 Owner’s Manual
5) FOOT SW jack
This is an unbalanced type phone jack. An unlatch type foot switch (Fostex Model 8051) can be plugged in
here. Operations using the foot switch are selectable in the [Setup mode]. Refer to [Setup mode] on page
27 for details.
6) DC IN connector
Plug-in the tip of the power cord of the exclusive AC adaptor (AD-9B) here and plug the adaptor into a
household AC wall outlet. Since the VM08 does not have a power switch, ON/OFF of power is done by
plugging and unplugging the AC adaptor from the AC wall outlet. If you don’t plan on using the VM08 for
some length of time, the AC adaptor must be unplugged from the AC wall outlet.
7) S/P DIF OUT connector
The same signals output from ST OUT L, R are output here as digital (S/P DIF) signals.
Signals mixed in an external digital master recorder connected here can be recorded in digital as shown in
the schematic. If external digital equipment to be connected is provided with only COAXIAL (RCA pin jack)
type IN/OUT connectors, use the optional Fostex COP-1/96k optical-coaxial converting adaptor sold separately.
* INPUT 5/6 (7/8) and AUX SEND 1/2 jacks
TRS type jacks used at INPUT 5/6, TRS type jacks used at INPUT 5/6 (7/8) and AUX SEND 1/2, and
TRS phone plugs or unbalanced phone plugs can be connected here, as shown below. The phone plug
should be wired as shown below.
TRS Phone plug Phone plug
INPUT 5/6, INPUT 7/8 jacks:
* How to input a stereo signal:
In order to input a stereo output signal to channels 5/6 or 7/8, a stereo cable with a STEREO
phone plug wired as shown in the schematic
should be used. Set the INPUT 5/6 input mode or
INPUT 7/8 input mode in the setup mode to [Stereo]. The L signal of the stereo input signal will
be applied to channel 5 (or 7) and the R signal to
channel 6 (or 8). Refer to [Setup mode] on page
27 to setup the input mode.
VM08 side
* How to input a monaural signal:
In order to input a monaural output signal to
channels 5/6 or 7/8, an unbalanced phone plug,
as shown in the schematic, is used for the connection and the INPUT 5/6 input mode or INPUT 7/8 input mode in the "setup mode" is set
to [In 5 > Mono] (or [In 7 > Mono]).
The monaural signal will be simultaneously input to channels 5 and 6 (or 7 and 8). When
setting the input mode, refer to [Setup mode]
on page 27 for details.
Music source side
AUX SEND OUT 1/2 jack:
* Connecting two external equipment:
Wire the TRS phone plug to two phone plugs as
shown in the schematic to connect two separate
pieces of equipment to AUX SEND 1/2.
By doing so, the AUX SEND 1 signal and AUX SEND
2 signal will be separately output to the two.
VM08 side
External Equipment
* Connecting a single external equipment:
In order to connect a single external piece of
equipment to the AUX SEND 1/2 jack, the unbalanced phone plug is connected as shown in the
schematic.
This will output only the AUX SEND 1 signal.
