A 500 Watt IP amplifier with metal housing, 1U.
Product Description:
The AF 500H provides a high output range and various connections from a microphone input to a relay output. That’s why the amplifier is universally suitable for any size of application – even for complex public address and Intercom solutions. In order to avoid cabling costs and be more flexible, the AF 500H is specifically optimized for installation either in a 19” rack or on-site.
Product Features:
- 500 watts total output power
- Supports IoIP and SIP
- 70 V/100 V audio output with loudspeaker line monitoring
- Class-D amplifier, optimized for high efficiency at low operating temperatures
- Short-circuit- and overload-proof
- Installation in a 19” rack or on-site
- Suitable for decentralized on-site use
- Rugged metal housing
- Line monitoring between amplifier and Intercom Server
