The RU-OSC4A is the ideal choice in many installations where either manual and/or automatic audio reference tones are required. Output connections are made on the rear panel through full-size, clearly identified, barrier block terminals.
The RU-OSC4A features four separate audio oscillators, operating at 100 Hz, 1 kHz, 7.5 kHz and 15 kHz. These frequencies provide quick, automatic verification of audio frequency response through a piece of equipment or an entire audio chain. A silent period between the 15 kHz tone and the 100 Hz tone provides time to verify system noise levels.
