| Audio input |
|---|
| Number/signal type | 1 stereo/mono, balanced/unbalanced input
2 stereo/mono, unbalanced inputs
(The three inputs are individually buffered and mixed together. Stereo signals are actively summed into a mono signal.) |
| Connectors | (1) 3.5 mm captive screw connector, 5 pole (main input)
(1) 3.5 mm mini audio jack (tip, ring, sleeve)
1 pair RCA |
| Impedance | >10k ohms balanced/unbalanced, DC coupled |
| Maximum level | +20 dBu (balanced, captive screw) or +4 dBV (unbalanced, RCA/TRS) at 1% THD+N |
| Input sensitivity | |
| RCA and TRS inputs | -10 dBV |
| Captive screw input | +4 dBu if driven by one input
-2 dBu if both inputs are summed |
| Input signal detection threshold | RCA and mini audio jacks: -44 dBv ±3 dB, unbalanced
Captive screw connector: -30 dBu ±3 dB, balanced |
| NOTE | 0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu |
