In-/Outputs and Control Elements
①
On/Off Switch
Switches the power supply on or off.
Note: In combination with an external power adaptor only the XR1-E will be switched off
and not the power adaptor itself. This means that the power adaptor still may consume
some current for its own ("stand-by"). It is recommended to disconnect the adaptor
completly from public power supply if the
XR1-E is not in use for a of longer time .
②
External Power Supply Input
Allows the operation with an external standard DC power adaptor. The connection is a
standard DC plug with 2.1mm diameter hole. By using the external power supply input ,
the internal batteries will be switched off. The input voltage may range from 6V – 15V.
Max. current dissipation is ca. 100mA (at 9V: ≈ 70mA). Take care on right polarity: The
"+"pole must be the outer contact.
③
Output
Connect to an amplifier etc. The output voltage can be selected by the attenuator switch
for best adaption to the consecutive stage (e.g. line-in or instrument amplifier)
④
Output Attenuator Switch
High: max. 8Vpp output voltage made for analog synthesizer inputs, line-in (mixer) inputs
etc..
Low: max. 0.8Vpp output voltage for instrumental amplifier inputs etc.
⑤
Instrument Input
Input jack for instrument or microphone. Impedance: ca 2MΩ; max. input voltage: ≤3.5Vpp.
⑥
Preamp Gain Control
Adjustment of the amplification of the input preamp.
⑦
Carrier Surpression Control
Controller for adjusting the oscillator (carrier) tone to its minimum. The "0" position in the
middle of the scale may be used as reference point, as well as the green LED – when dark
(and without input signal) – is suitable for indication of a minimum carrier tone amount.
Note: There will always remain a little bit of the oscillator sound (2 nd harmonics etc.). For
best performance, make sure that the input signal level is high.
⑧
Bypass Control
Ratio between input signal (preamplified) and effect signal. Turning the knob fully left will
provide the preamplified input signal only; by turning the knob clockwise the effect signal
will increase more and more and the original (dry) signal will disappear.Fully right position
= "
100% ": the pure ring modulation effect signal.
⑨
Footswitch Input
Input jack for external bypass control, e.g. by a footswitch
•
Switch opened: The dry preamplified input signal
•
Switch closed: The effect signal (also depending on postion of the " Bypass " control
pot )
The switching also can be controlled by an external logic signal (0V = effect , +5V = dry),
e.g. a gate signal from a synthesizer.
