What is the OEX-6sr Output Expander?

The

OEX6sr

is a multi-function digital device that adds six

individual outputs, or three additional pairs of stereo outputs to an
ASR- 10, ASR-88, or EPS- 16 PLUS keyboard, enhancing the
capabilities and flexibility of the ASR/EPS-16 PLUS.

The power of the OEX-6sr Output Expander lies in its unique
configuration: six individual outputs or three stereo pairs (AUX 1,
AUX 2, AUX 3). The addition of these outputs allows you to
route separate signals for independent processing, or isolate parts
for click or monitoring references. Even individual WaveSamples
within an instrument (for instance, the snare and kick drum from a
drum kit) can be sent to different outputs for discrete external
effects processing (such as with the ENSONIQ DP/4+ Parallel
Effects Processor). The design of this product resulted from
customer requests for a multi-purpose output device that could be
configured with stereo outputs and/or individual outputs. As with
any product, getting to know its operation will help to increase
your productivity and enhance the performance and expression of
your music.

IMPORTANT! Because the OEX-6sr is a digital device, no audio
signal passes through the connector cable from the ASR/EPS-16
PLUS to the OEX-6sr.

Do not connect this cable to any other
device that uses a similar connector (such as a Macintosh), as
this will damage both units and void their warranties.

Important points about the OEX-6sr

l

Never connect the OEX-6sr while the power to the

ASIUEPS-16 PLUS is on. This will damage both units
and void their warranties.

l

The signals sent to AUX 1, AUX 2, and AUX 3 on the

OEX-6sr are dry; these outputs do not pass signals with
effects. The wet signal is only present at the Main
Audio Outputs.

l

The AUX 1, AUX 2, and AUX 3 outputs on the OEX-

6sr are always active when the

OEX-6sr

is connected;

see the signal flow diagram.

l

The Outputs on the OEX-6sr are not affected by the

ASR/EPS- 16 PLUS master Volume Slider.

l

Assigning of sounds to the

OEX-6sr

can be handled two

ways; at the WaveSample level or at the track level.

Setting-up the OEX-6sr

Although you can set-up your OEX-6sr any way you like, we
suggest using one of these practical mounting methods:

Rubber Feet Only Mount

Here’s what you’ll need to get started:

1)

2)

l OEX-6sr Output Expander

l

Six foot connection cable (cable lengths of 10 feet or
longer may not give optimal results, and are not

recommended by ENSONIQ)

l

Four rubber feet (included)

Apply rubber feet to the bottom of the

OEX-6sr.

Place the OEX-6sr in the

position of your choice,

such as the recess over the

ASR/EPS-

16 PLUS logo,
or on the floor beneath
your keyboard stand.

Velcro Only Mount

Here’s what you’ll need to get
started:

3)

l OEX-6sr Output

Expander

l

Six foot connection cable (cable lengths of 10 feet or

longer may not give optimal results, and are not

recommended by ENSONIQ)

l

Two strips of adhesive velcro (included)

Position the

OEX-6sr

on the top

right corner of the

ASR/EPS-16
PLUS. It fits comfortably in
the recess directly over the
ASR/EPS-16 PLUS logo.
Mark the position with
masking tape (not included).

Place the “furry” side of the

two adhesive velcro strips

2

OEX-6sr

Operation Manual

(included) in the position marked by your masking tape.
Remember to remove the masking tape and discard. Then

place the “hook” side of the velcro strips on the bottom of

the OEX-6sr. Use your thumb to apply pressure to all
velcro strips to ensure a secure fit. Keep in mind, that it

could be difficult to remove the velcro from the front panel

of the ASR/EPS- 16 PLUS at a later time.

You should now be able to place your OEX-6sr on the velcro strips
and have it remain in position. We suggest cleaning the velcro
strips periodically to maintain a secure fit.

Rubber Feet and Velcro Mount

Here’s what you’ll need to get started:

l

Two strips of adhesive velcro (included)

It is also possible to mount the
OEX-6sr with a combination of
rubber feet and velcro. Apply
the rubber feet to the bottom
front of the

OEX-6sr

as shown

in the illustration.
Mark a location on the upper
right hand lip of the

ASR/
EPS-16 PLUS. This is
where your velcro will be
positioned (the velcro is
mounted horizontally in this application).
Place the “furry” side of the two adhesive velcro strips
(included) in the position marked by the masking tape.
Remember to remove the masking tape and discard. Then
place the “hook” side of the two velcro strips on the bottom
of the OEX-6sr. Use your thumb to apply pressure to all
velcro strips to ensure a secure fit.

OEX-6sr

Operation Manual

1) Position the OEX-6sr on the optional rack shelf, aligning the
two outer holes on the bottom of the

OEX-6sr

with a pair of
holes on the rack shelf. The OEX-6sr can be mounted
facing either way, but we suggest facing the Output jacks of
the OEX-6sr towards the front of the rack shelf. This will
aid in quick changes for recording purposes.

2) Attach the OEX-6sr to the rack shelf using two (included)
screws.

3)

Once the

OEX-6sr

is attached to the rack shelf, you can

mount the shelf into a rack mount housing.

Turn the OEX-6sr upside

OEX-6sr can be positioned
in a variety of ways. One

OEX-6sr

Operation Manual

of the simplest mountings would be to remove the
microphone holder from a mic stand and attach the

OEX-6sr

(flange) to the stand.

Connecting the

OEX-6sr

Once the

OEX-6sr

has been mounted, connect the multiplexed

input of the OEX-6sr to the Output Expander jack on the

ASR/

EPS-16 PLUS, with the enclosed connection cable.

Important! Power to the

ASR/EPS-16

PLUS must be off prior
to connecting or disconnecting the OEX-6sr. Connecting the
OEX-6sr with the power on can cause damage to the

ASR/

EPS-16 PLUS and/or the OEX-6sr itself.

Understanding the ASR-10/ASR-88 Output Busses

A sound in the ASR can be assigned to one of six stereo sends,
which we call busses. An understanding of how these busses are

routed to the OEX-6sr, as well as to the ASR Main Audio Outputs,

is crucial to your getting the most out of the OEX-6sr. The signal
flow of the six output busses is shown in the diagram on the facing
page. We suggest you study it carefully, as it can answer many of
your questions regarding what signal will be routed where.

When the PAN parameter is set to -99, the sound will be sent only
to the left signal of the bus. When the PAN parameter is set to

+99,

the sound will be sent only to the right signal of the bus. This

is how you can create six individual outputs.

The six output busses are as follows:

* BUS 1,2,3

Sounds assigned to these busses will always be

routed to the

ASR’s

internal effects processor and on

to the Main Audio Outputs.

l

AUX

1,2,3

Sounds assigned to these busses will always be

routed to the output labeled AUX 1, 2, or 3 on the

OEX-6sr,

and only to that output. Sounds assigned to

AUX 1,2, or 3 will always be dry, with no effects
processing.
