Connectors and controls on the rear panel
Balanced input
This balanced Combo socket serves for connecting balanced sources
with male XLR or 1/4" TRS jacks. Alternatively, an unbalanced male TS
jack can be inserted to the socket. For unbalanced operation with a TS
connector the minus signal is automatically grounded.
Ground Lift switch
This switch decouples the earth conductor of the speaker electro-
nics from the audio connectors ground. This is especially useful if any
ground loops occur due to a doubled grounding via the power supply.
Switch it to left means the unit is not earthed, while turn it to right
means that the unit is earthed now.
System Gain control
With this knob you can adjust the playback volume for every Ra-
dioCheck monitor separately between -30 and +6dB. For stereo use
please make sure that the volume controls on both speakers are
equally balanced. Otherwise the acoustic balance between both
speakers and therefore the stereo image could be damaged.
Power switch
This switch turns the internal power amplifier in RadioCheck on and
off. Please note that the speaker is still connected to the external DC
adapter and hence with the mains supply even when the switch is in
the Off position.
DC in jack
The supplied mains adapter is plugged to this socket. Tighten the lock
screw of the cable/connector securely for reliable operation.
NOTE
At the factory the power supply adapter has been pre-set to the mains
voltage in your country. For use abroad you can set another voltage
via the switch on the external power supply adapter.
Placement
The Nowsonic RadioCheck can be installed on appropriate stands or on
the bridge of your mixing desk. When positioning the monitors it is best
to keep them at ear level and slightly angled in towards your listening
position. The optimum stereo listening perspective is achieved by for-
ming an equilateral triangle with an equal distance from each monitor
to the other and to your ears (the distance between the monitors and
your ears should be quite the same).
Connecting and setting the monitor level
Before plugging in and powering up your RadioCheck speakers please
take a moment and make sure that the power supplies are properly set
according to your local mains voltage.
Connect your source (mixing desk, monitoring controller etc.) to the
balanced inputs on the rear of the speakers using appropriate cables.
Set all faders and level controls on your source to minimum.
Power up all other equipment first and then your RadioCheck
monitors: This ensures that the speaker will not be damaged by any
switch-on pulse.
The volume control on the rear of your RadioCheck monitors is set at
minimum at the factory so as to avoid an accidental overload upon
initial hookup. This is intended to force the engineer to accurately
adapt the rear panel gain controls to the output level of the source
and to the desired listening level.
When powering down your system, turn off the RadioCheck first and
then all other source devices, This ensures that the speaker will not be
damaged by any turn off spikes.
