* Note: Be careful with DB25 tascam standard/premade cables. The digital AES/EBU
cables have their inputs and outputs swapped compared to the analog version.

Outputs:

On the rearpanel you will find 2 outputs with balanced gold-plated Neutrik XLR’s.

Power:

Power is provided by a standard grounded IEC input connector with a build-in fuse. Input
voltages are automatically selected from 100-250VAC 50/60hz.

Hardware:

This device is built around mostly passive circuits, but some sections need to be active, but
always with transparency in mind. The sturdy frontpanel-switches have, depending on their
function, 2 color leds for visual feedback. All relays are high sensitive, long-life (15.000.000
cycles) Omron Relays.

Stepped switches are military grade Blore Edwards for long life and really nice mechanical
feel. In and output connectors are gold-plated Neutrik, DB25 inserts are gold-plated wurth
connectors. Active circuits make use of analog devices and THAT drivers. The mid/side
circuit

is

based

on

the

well-known

circuit

from

Wayne

Kirkwood,

but

with

additions/modifications.

The internal PSU section is build around industrial-grade Meanwell SMPS’s which run way
more silent and are way more efficient then old-school linear PSU’s. Both the relays/leds
and active circuit PSU’s are running on their own separate PSU.

When this device is used in passive mode, so without active stages, it’s 100% passive and
only relay-contacts are inline. This means it’s basically a straight wire.

Pushswitch labeling:

To have some extra visual feedback on the push-switches you can put labels under the
switch-covers. You can simply, but carefully, remove the switch cover with a small
screwdriver and put something like a transparent dymo letratag sticker on the white plastic
piece inside the switch-cover.

More info and a manual can be found on our website.
