INTRODUCTION
Thank you for your purchase of the MO2020 Testoscillator. The MO2020
is designed to provide a sine wave, or square wave via 1/4" unbalanced
jacks, for testing audio devices. The units frequency output varies from
20Hz to 24kHz.
DESCRIPTION
FRONT PANEL
Output Pad: When depressed, the output level is dropped by 10 dB.
Frequency: Varies the frequency generated by the MO2020 from 20Hz to
24kHz. PLEASE NOTE: THE FREQUENCY MARKINGS ON THE
MO2020 ARE APPROXIMATE AND MAY VARY. FOR ACCURATE FRE-
QUENCY SELECTION, USE A RELIABLE FREQUENCY COUNTER.
Sine Level: Controls the output level of the Sine Out jack.
SQR Level: Controls the output level of the SQR (square) Out jack.
REAR PANEL (Labeling for the rear panel is located on the top of the unit)
VCO Input: 1/4" jack for connection to a Voltage Control source which
may vary from 1.2 volts to 5 volts dc. This voltage allows for external
control of the MO2020's frequency. THE FREQUENCY CONTROL MUST
BE SET TO MAXIMUM FOR PROPER OPERATION OF THE VCO
CONTROL.
Sine Out: 1/4" unbalanced jack containing the sine wave signal.
SQR Out: 1/4" unbalanced jack containing the square wave signal.
DC Loop: Paralleled power jack for connection to another MO2020.
DC In: For connection to the included Rolls power supply.
SPECIFICATIONS
Output Level: +11 dB S
+14 dB S
