DA4140-DSP

The second of a new generation of Procella power amplifiers, the DA4140-DSP is a highly versatile, dynamic yet affordable high-performance audio solution. Designed with Pascal A/S in Denmark and using their highly-acclaimed amplifier modules, this four-channel amplifier is ideal for use with all Procella speakers, from the P1 to the P610 Mk II and will drive a P15 subwoofer.

Delivering a solid 4x140W or 2x 280W in 8ohms, the high-efficiency class-D DA4140-DSP ensures a wide dynamic range with low-frequency impact and a transparent and musical sound quality that will satisfy the critical listener.

Description

Procella’s DA4140-DSP high-efficiency class-D power amplifier provides Procella enthusiasts with a versatile and compact solution that occupies just a single half-rack space.

It can be used as a four channel amplifier at 140W per channel, or as a two-channel amplifier ‘bridged’ to deliver 280W each. Its uncompromised dynamic output and transparent sound quality are an ideal complement for a wide variety of Procella loudspeaker configurations.

The DA4140-DSP is available in three versions:

  1. No DSP program
  2. P610 Mk II (biamplified with active crossover, one amp per speaker)
  3. P15 subwoofer (one amp per subwoofer).
