A 20 Watt amplifier with polycarbonate housing.
Product Description:
Their compact design makes the 20 Watt amplifiers ideal for a decentralized, cable saving installation next to PA loudspeakers and Intercom terminals. To provide even greater flexibility, the analogue amplifiers are available as add-in modules that integrate easily into the Intercom terminals themselves.
Product Features:
- 20 watts total output power
- Supports IoIP and SIP
- Class-D amplifier, optimized for high efficiency at low operating temperatures
- Short-circuit- and overload-proof
- Suitable for decentralized on-site use
- Rugged polycarbonate housing
- Line monitoring between amplifier and Intercom Server
- Can be used as an interface to PA systems
- Low impedance audio output; min. impedance: 4 Ω
