Operation - Conrad MP Studio V3 Bedienungsanleitung

• Connect the output from your audio source to the INPUT (1).
The stereo socket is suitable for instruments and line level signals. It has a high input
impedance and can process signals up to +22 dBu.
The XLR input is mainly suitable for microphones and can also provide phantom
powering. It processes signals up to +14 dBu, which is suffi cient for all microphones.
The intermediate and constant input impedance covering in a wide frequency band
of this input makes a neutral sound playback of almost all microphones possible.
• Connect the OUTPUT socket (2) with the input of the following audio device. A symmetric
(XLR) and an asymmetric (stereo) connection is available.
Both inputs (XLR and stereo input) as well as both outputs can be used simultane-
ously.
When using both inputs, the device amplifi es the total signal of both connected input
signals.
Connecting the Power Unit
When connecting up the power unit make sure fi rst that the voltage data on
the type plate of the power pack is compatible with the mains voltage avail-
able. Do not connect the power unit if the data doesn't comply with the avail-
able mains voltage. The wrong supply voltage may lead to irreparable dam-
ages to the device and involve risks for the user.
The mains socket must be in close proximity to the device and also be easily
accessible after the power unit is plugged in to ensure its fast and safe discon-
nection from the power grid in case of malfunctioning of the light effect device.
Make sure that the connection cable is not being pinched or damaged by
sharp edges.
If you do not use the device, unplug the power plug to switch the device off.
• Plug the low-voltage plug of the power unit into the PWR 9VAC socket (3).
• Plug the power unit into the mains socket.
• As soon as the microphone amplifi er is supplied with current the operation indicator (6) is lit.
red > limiter is active or delay when switching on
green > ready for operation

Operation

• Connect the device to the power supply as described above.
• Adapt the input sensitivity to input signal using the INPUT controller (7) control.
• The control range of the INPUT controller (7) can be extended with the GAIN switch (8) by
+20 dB. The GAIN switch (8) should be pressed down for microphone signals; it should not
be pressed down for line level signals.
• Adjust the volume of the output signal with the OUTPUT controller (11).
• Use the VU-meter (4) for guidance when adjusting input sensitivities and output volume. It
shows a reading of the output volume of the microphone amplifi er. When OPL is activated (see
VOICING controller (5)), overdrive is prevented by the built-in limiter. Avoid overdrive exceed-
ing the 0 dB mark when OPL is not activated.
• The operating display (6) not only shows the readiness for operation (green) but also distor-
tions or activation of the limiter (red). When OPL is not activated, the operating display (6)
must only light up briefl y in red. If it is lit up in red for longer, lower the input volume using
the INPUT controller (7). The operating display is lit up during activated OPL when the limiter
limits the signal automatically.
• The VOICING controller (5) can be used to adjust sound characteristics to your application
and taste. The different settings are explained in more detail further below in these instruc-
tions. In the OPL range, a limiter is activated automatically for the output to avoid overdrive.
Experiment a little with the pre-settings in order to achieve the optimal effect.
• A condenser microphone without its own power supply can be powered with integrated phan-
tom powering if it is connected to the XLR input. To do this, press the P-PWR switch (9).
When the switch is pressed down, a direct current of 48 V is present at the pins 2 and 3 of the
XLR input.
Before switching the P-PWR switch (9) on or off, please turn the OUTPUT controller
(11) to a minimum and wait for 30-45 seconds to avoid interfering noises.
• The PHASE REVERSE switch (10) reverses the phase of the output signal. This may be
useful when e.g. two microphones transmit the same acoustic source from different locations.
The sound may be hollow or thin due to phase shift. In such cases, try to press the PHASE
REVERSE switch (10) to improve the sound.
Settings of the VOICING controller
Here, you can adjust the used instruments or the desired sound characteristics in order to
select the pre-settings made by professionals and sound engineers.

Maintenance and Cleaning
Please use a soft, dry, clean cloth for cleaning.
Do not use any chemical cleaning agents, as they can discolour the surface fi nish of the hous-
ing.
Disposal
Electronic devices are recyclable waste materials and must not be disposed of in the
household waste!
Dispose of an unserviceable product in accordance with the relevant statutory regu-
lations.
