You Need The ST-OSC2A or ST-OSC2B!
APPLICATION: Each of the ST-OSC2 products is a Dual Audio Oscillator in the group of STICK-ON
series products by Radio Design Labs. These products are designed for quick, convenient installation and
reliable operation in a variety of audio applications.
TWO MODELS TO FIT SPECIFIC APPLICATIONS:
ST-OSC2A: This module is designed to provide separate left and right audio signals for each of two
frequencies: 1 kHz and 10 kHz. This module is well suited to audio installations requiring reference tones
for level calibration and frequency response checks.
ST-OSC2B: This module is designed to provide separate left and right audio signals for each of two
frequencies: 100 Hz and 400 Hz. This module may be used in conjunction with the ST-OSC2A to provide
a complete set of frequency response test tones (100 Hz, 400 Hz, 1 kHz, 10 kHz), or in systems where
400 Hz is used as the reference tone frequency.
FEATURES IN COMMON TO BOTH ST-OSC2 PRODUCTS:
•
•
•
•
•
Low-impedance output drives virtually any audio line
Outputs may be connected to either balanced or unbalanced lines
Multi-turn level adjustment permits precise output setting
Separate output level control provided for each oscillator
Integral AGC circuitry provides stable output level
All this is available in the unbelievable compactness and convenience of the RDL STICK-ONs. Put them
right where you need them, or design them in with our optional racking kits. Anytime you need stable
reference tones in any audio or recording system, your simple, cost-effective solution is found in the
ST-OSC2 product group!
