- 2 Watts RMS into 8 Ω
- +12 dBu Into 600 Ω
- Quality Utility Amplifier
- Intercom Driver
- Music-On-Hold Driver
The ST-PA2 features a single, unbalanced audio input, a gain control, and two outputs. The first output is designed to deliver a clean 2 watts RMS into an 8 Ω speaker. The second output is intended to drive 600 Ω transformers, typically on equipment inputs. This makes the ST-PA2 uniquely suited to applications such as music-on-hold inputs on telephone systems which may have either 8 Ω or 600 Ω inputs. If desired, both outputs may be used at the same time. | Input: | Unbalanced 10 kΩ | | Input Level: | -15 dBV minimum (for rated power output) -20 dBV minimum (for 1 watt RMS into 8 Ω | | Frequency Response: | 35 Hz to 30 kHz (8 Ω +/- 1.5 dB) 20 Hz to 30 kHz (600 Ω +/- 0.5 dB) | | THD+N: | < 0.75%; 0.5% typical | | Noise: | < -80 dB (8 Ω @ 2 W RMS) < -70 dB (600 Ω, referred to +4 dBu) | | Outputs (2): | 1 @ 8 Ω, 2 watts RMS maximum 1 @ 600 Ω, +12 dBu maximum | | Power Requirement: | GROUND-REFERENCED, 24 to 33 Vdc @ 250 mA | | Ambient Operating Environment: | 0° C to 50° C |
