- RDL® SupplyFlex™ Power Input Configuration
The ST-DA3 gives you the advantages of an audio distribution amplifier PLUS you can put it where you need it. The ST-DA3 allows bridging of any audio line, adjusting the gain, and driving up to three high or low impedance, balanced or unbalanced loads. The ST-DA3s wideband circuitry produces the unsurpassed pure clarity, low-distortion and low-noise for which RDL products are known. The ST-DA3 features RDLs SupplyFlex power input configuration. The module will operate directly from floating 24 Vdc or bipolar dc power. If a jumper is connected between the PWR minus terminal and any module ground, the module power becomes ground-referenced. | Input: | 20 kΩ balanced or unbalanced | | Input Signal: | -15 dBV to +21 dBu (for +4 dBu output) | | Maximum Input Level: | +24 dBu | | Outputs (3): | 150 Ω balanced or 75 Ω unbalanced | | Output Signal: | | | Balanced: | +4 dBu nominal balanced; | | Unbalanced: | 6 dB below balanced line level | | Maximum Output Level: | +25 dBu | | Frequency Response: | 10 Hz to 100 kHz (+/- 0.05 dB) | | THD+N: | < 0.002% (unity gain) | | IMD: | < 0.003% (unity gain) | | Noise below +4 dBu: | < -98 dB (unity gain) | | Headroom: | > 20 dB (above +4 dBu) | | Gain: | Unity +/- 17 dB (adjustable) | | CMRR: | > 60 dB (50 Hz to 120 Hz) | | Power Requirement: | GROUND-REFERENCED or FLOATING, 24 to 33 Vdc @ 70 mA |
