DIN rail mount PA Audio Amplifiers Public address systems, for speech and music reproduction
AD-300
The AD-300 series consists of digital integrated systems and audio equipment components designed for the PA (Pubblic Address) of audio messages and music. All the audio amplifiers, such as the accessories are housed in containers suitable for standard DIN rail mounting and have 2 audio inputs and an output for 4-8-16Ohm speakers or on 100V PA line. The AD-301 model also has a "ducking" input (attenuation of a channel in the presence of the second channel) and an output for breakdown or malfunction warning. AD-301 is made entirely in digital technology and integrates a DSP (Digital Signal Processor) capable of processing audio signals in 24-bit mode and 96 KHz sample rate to ensure the highest fidelity possible.
Power Supply: Maximum output power: Max efficiency: Minimum output impedance: Total harmonic distortion (THD): Max input signal: Input impedance: Bass equalization: Treble equalization: N. audio input channels: Mount type: Dimensions:
8÷18 Vdc, max 2A cons. 30 Wrms @ 4 ohm, 16Vdc 82% ÷ 90% 4 ohm 0.05% @ 1W / 1KHz 3Vpp 10Kohm +/- 18dB steps of 1dB (AD301) +/- 18dB steps of 1dB (AD301) 2 DIN rail 3U DIN
AD-301 is also equipped with a class D amplifier that has a maximum power of 30 Wrms @ 4 ohm and with supply voltage that can range from 8Vdc to 18Vdc. The amplifier is self-protected against short circuit on the load. The Class D amplifier and accessories can be installed systems within an electrical panel, thanks to low heat production. AD-301 is ideal for making sound systems suitable to make announcements in public places, in company and outdoor.
