1. Introduction
The OTECABLES DIVerse direct box is a product designed for all demanding musicians and audio professionals from live
audio world or recording studio field. Thanks to the amazing quality and careful choice of components, the DIVerse is
able to capture sound of any instrument with greatest clarity. Precisely optimized passive electronic design leads to
unmatched signal to noise ratio and linear transmission without any degradation of the signal. When overdriven, the
famous LUNDAHL transformers does not distort, instead they provides warm analog saturation with rich, pleasant
harmonics. Blue and green mono models feature a 6,3 mm TRS jack output behind the transformer section. All the
products in the DIVerse line are able to eliminate buzz or hum caused by ground loops in the signal chain. Heavy duty
design of DIVerse DIboxes is ready to withstand the rough conditions on the road and to maintain performance stability
for recording applications.
2. DIVerse models
DIVerse BLUE is the universal live and recording tool specificaly designed for low impedance audio sources, such as
keyboards, synthesizers, guitars and basses with active pickups, audio interfaces, effect pedals or guitar amplifier
outputs. It features the LUNDAHL general purpose LL1570 transformer. The input is transformed with 1:1 ratio (default
setting), so the output signal is transferred at the original level with maximum clarity. In addition DIVerse BLUE offers
an extra option of feeding an extremely long audio signal conduction from the DI’s output. This is a big advantage in
situations where, for example, analog vintage gear used at the Front Of House at a large stadium show. For these
occasions the electronic unit of DIVerse products offers the possibility to internally reconfigure the circuit to provide
extremely low impedance output of 150 Ohm with 2:1 conversion (thus with -6dB level correction). DIVerse BLUE is
available in both mono and stereo version.
DIVerse GREEN HiZ model is a classic DI box tailored for high impedance audio sources, like basses and guitars with
passive electronics or Hammond organ. It features the LUNDAHL LL1935, the DI designated transformer. The input is
transformed with ratio 10:1 (internally switchable to 5:1) which allows to preserve the whole frequency spectrum of
the signal without any loss of dynamic range over long output cable connections.
DIVerse RED ISO model is a stereo galvanic isolator. It features the very high-level LUNDAHL LL1588 transformers,
which can operate at extremely high input levels without any kind of signal coloration. Compared to the BLUE model,
the line level can be EIGHT times higher before any noticeable saturation of the signal occurs. This feature makes it
most suitable for applications where you need to transport high levels of signal without compromising the lowest
frequencies, for example when you need to interconnect line-level devices like mixing consoles, PA processors,
amplifiers, DJ equipment, modular synths, recording and broadcasting units, distant PA delay zones, etc.

3. Uses for your DIVerse –Examples
DIVerse BLUE
For the best results using isolated parallel output and isolated output in the same time, please connect the stage amp with balanced
line. Some configurations when unbalanced TS connection to the stage amp is used along with the balanced XLR connection to the
sound system can cause the degradation of the signal path resistance against the electromagnetic interference and ground loops.
In case of the unwanted noise occurred, please use rather the standard Thru connector to feed your stage amp instead.

Internal output impedance switch (BLUE and GREEN versions)
In order to drive an extremely long line or to connect to a low impedance input, the Di-Box can be internally switched
to half "Lo" output impedance with a corresponding additional attenuation of -6dB (resulting 10:1 conversion ratio for
GREEN, 2:1 for BLUE).
Default settings:
DIVerse BLUE –Hi (0dB), 1:1 ratio
DIVerse GREEN –Lo (-6dB), 10:1 ratio
