0 RU-OSC4A Sequencing Oscillator - 4 Frequencies
RU-OSC4A Sequencing Oscillator - 4 Frequencies | | - Automatic Reference Tones
- Verify Audio System Response
- Manually Selectable Audio Tones
- Line‑Level Audio Output
- Balanced/Unbalanced Output
- Gain Trim for Each Frequency
| 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. | Typical Performance: | Frequencies: | | 100 Hz, 1,000 Hz, 7,500 Hz, 15,000 Hz | Output Level: | | Each frequency individually adjustable Off to +8 dBu | THD+N: | | < 1% (1 kHz to 15 kHz); <3% (100 Hz) | Residual Noise: | | < ‑75 dB (referred to +4 dBu during silent period) | Indicators: | | Front‑panel LED indicating selected channel; HOLD LED to indicate suspended sequencing | Rate Control: | | 3 sec. to 30 sec. (sequencing rate front‑panel adjustable) | Output: | | 1 Balanced @ 150 Ω to drive high or low impedance balanced or unbalanced line | Power Requirement: | | GROUND‑REFERENCED, 24 to 33 Vdc @ 75 mA |
