safety documents. (see below)
If you are passing the unit over to third parties, please make them aware of these documents.
Any use outside of the applications described in this manual may cause damage to the product. The
product must not be altered or modied. Any improper usage may cause multiple hazards such as
electrical shorts, re, electric shocks, and other hazards.
The enclosed safety and hazard notices refer to the installation and operation in an api®500 system.
There may be relevant guidelines and regulations that aect the operation, even if they do not apply to
our product directly. The installation and operation should therefore be carried out by trained personnel
only.
Operation of the unit in adverse environmental conditions - such as moisture and / or excessive

Function, controls and their eect
M/S technology - The term M/S technology means that a stereo signal is divided into its mid and side
signal components. The mid signal (M) contains all signals that are identical on the left and right side.
The side signal (S) contains the non-identical signal components. After the mid (M) and side (S) signals
have been processed separately (usually with equalizer, compressor, limiter, reverb, delay or lter), the
signals are then precisely merged again to form a stereo signal.
Function - The W2389j module in the api®500 format represents a compact and precise M/S encoder
and M/S decoder in an api®500 double cassette format.
Stereo in-and outputs are provided on the backside of the connected lunchbox.
The in-and outputs on the frontside of the W2389j are used to connect the M and S signals with any
external processing device.
Controls
mode The illuminated M/S push button enables a quick and visible change between the M/S and
the stereo signal processing. This allows a quick and reliable eect assessment of the inserted signal
processors.
bypass L/M This illuminated push button is used to check the mid signals (in M/S mode) or the
components of the left channel (in stereo mode).
bypass R/S This illuminated push button is used to check the side signals (in M/S mode) or the
components of the right channel (in stereo mode).
W2389j (f) M/S-Master junior application examples
• Microphone recording using M/S microphone setup
(in this application the two microphones are connected to the lower XLR sockets on the front panel)
• Conversion of stereo signals into mid and side signals
• Conversion of the mid and side signals back into a stereo signal
• Converting into M/S signals, to modify the stereo base width by changing the side component level.
It is sucient to plug to the XLR in- and outputs of the side signal (R/S) and then press the bypass L/M
switch (e.g. with a symmetrical voltage divider or a symmetrical potentiometer)
• Post correction of the stereo width from mono to overbase width (super-wide stereo). To reduce the
stereo base, the side signal components must be reduced and to enlarge the stereo base, they need to
be increased. Suitable accessories can be supplied on request.
• Separate editing of mid and side components for further processing by external signal processors
• Reweighting of reverb and soloist parts in existing stereo recordings
• Insert of vintage and/or mono devices in M or S. Suitable adapters from balanced to unbalanced signal
routing can be delivered on request.

Installation of the W2389j (f) M/S-Master junior in an api ® 500 system
Electric potential dierences and electrostatic discharges (ESD) can destroy your api ® 500 system and the
W2389j module.
Please ensure to discharge any potential electrostatic charges by touching a plumbing pipe, heating pipe
or any other piece of metal connected to earth before installing the W2389j module. Achieving a neutral
electric potential is always required for any installation, reconguration or handling of electronics modules
and their interconnections.
Turn o your api ® 500 rack or console and all connected devices. Remove any blank panels that might
cover the slot you have chosen for installation of the module.
Center the module between the two threaded mounting holes and evenly insert the module into the free
slot without applying brute force. Make sure the module is tightly attached. Secure the W2389j module
with both screws. The W2389j M/S-Master junior module is ready for operation once the appropriate
connections on the rear of your api ® box have been made.
Recycling
Please stay eco-friendly and dispose of all defective and obsolete devices at a certied
collection facility according to local laws and regulations..
