  • 75 W total output power at 25 VRMS (all DAA2-7525 models).
  • Supports two Class A high-level audio outputs; or four Class B outputs.
  • Optional BDA amplifiers support alternative configurations.
  • Backup amplifier – supports one-to-one backup (all DAA2 models).
  • Primary amplifier – supports two-channel operation (all DAA2 models).
  • Supports one-to-many amplifier backup applications using the same model DAA2.
