FUNCTIONAL DESCRIPTION
The OPAL-22 allows to pre-amplify and record two analog audio signals into a connected PC via a USB
2.0 connection with low latency ASIO technology (PC only). Branded converters with high resolution and
sampling rate grant pristine and untainted signal quality. To prepare the recording, the input signals can
be monitored directly. To complete the PC connectivity, a MIDI interface is built in.
NOTE: Below description of functional element 4 to element 9 refers to the Input section (A) as pictured
opposite. All elements for input section (B) are identical.
1: USB 2.0 port. This is a type B connector for connection to a PC with the supplied cable.
2: MAIN OUTPUT. This is a pair of ¼” (6.35 mm) balanced TRS jack sockets. These jacks carry the same signal
as the monitor jack (10), but cannot be controlled locally in terms of volume, and are not affected by the
direct monitor switch (12).
3: MIDI interface. This is a pair of standard 5-pin DIN connectors. Allows the connection of compatible MIDI
equipment for receiving and sending MIDI information from and to the connected PC.
4: Microphone input. This is a standard female balanced XLR connector to connect dynamic or condenser
microphones. Phantom power for condenser microphones can be activated via the switch (13).
Keep phantom power off when using with dynamic microphones.
5: Instrument input. This is a ¼” (6.35 mm) balanced TRS jack. The impedance of this input is switchable to
match high- or low-impedance sources via the switch (6).
6: Impedance switch for instrument input. Switches the input impedance to match high- or low-impedance
sources connected to the instrument input (5).
7: Instrument/Mic input selector. Determines whether the microphone input (4) or the Instrument input (5)
is the active input.
8: GAIN control. Sets the input gain for the chosen active input. Observe the Overload (”OVL”) LED (9) while
setting the gain, to make sure that the LED only lights up occasionally at the highest peak levels of the input
signal, in order to find the best gain setting.
9: OVL (Overload) LED. Indicates when the GAIN control (8) is set too high and internally safe signal levels
are exceeded.
10: MONITOR output. Carries the same signal as the MAIN output (2), but can be adjusted in its volume via the
monitor volume control (11). Further, the inputs can be routed directly to the MONITOR output when the
D-MON switch (12) is pressed.
11: MONITOR LEVEL. Determines the volume at the monitor output (10).
12: D-MON switch (direct monitoring). Adds the input signals of input section A and B to the monitor
output signal. If monitoring of the input signals only is required, mute the replay of audio from your DAW
on your PC.
13: Phantom Power switch. Activates +48V DC phantom power supply to the microphone inputs (4).
Only for use with condenser microphones which require phantom power. Keep this switched off when
using dynamic microphones.
14: USB bus activity LED. Indicates ongoing data traffic on the USB bus.
15: MIDI bus activity indicator. Indicates ongoing data traffic on the MIDI bus.

USAGE EXAMPLE CONNECTIONS
The OPAL-22 use the below connector types, for which the pin assignment must comply with
the following specification. Always make sure to use good connectors and cables to ensure
proper operation. Balanced connections are to be preferred over unbalanced connections
where applicable and feasible. Avoid unbalanced connections exceeding 2m of cable length.
MAINTENANCE AND WARRANTY
While we have chosen the best components to make this product as rugged and reliable
as possible, some parts in audio products (potentiometers, faders, switches) are subject to
wear which is a matter of operation cycles, and not of time.
In many cases, malfunction of electro-mechanical parts occurs due to dust contamination,
which may require cleaning of such parts. As the inside of such parts is not accessible,
a common practice is to use cleaning fluids in the shape of sprays. Please be reminded
that many of such fluids contain chemicals which may wash away the dust but at the same
time corrode or damage contact surface and may cause cosmetic damage to other parts.
We hence explicitly exclude any claims for exchange of damaged part due to mechanical
or chemical impact.
