Description

DELTA12.2-DSP Audio Amplifier

The DELTA12.2-DSP amplifier is a high-performance two-channel power amplifier with a built-in DSP loudspeaker management. The integration of Hoellstern's proprietary DSP controller gives the DELTA12.2-DSP amplifier extra benefits over traditional solutions with separate components. Due to the precise and comprehensive Hoellstern® loudspeaker libraries the DELTA12.2-DSP amplifier offers additional benefits as a loudspeaker brand independent solution with a decisive advantage over conventional system components.With their two individual audio inputs and two individual audio outputs Hoellstern® amplifiers are perctly suited for all applications. The high sound quality, the extraordinary flexibility and the great overall quality are lasting guarantors for a future-proof investment which will amortise quickly and make the daily routine of professional sound technicians a lot easier. Hoellstern amplifiers are system.
