Mc2 Delta 40 SLAVE

MC² Delta 40 Slave – 4‑Channel Slave Power Amplifier

The MC² Delta 40 Slave is a streamlined version of the Delta Series amplifier line. Designed to operate under control of a master Delta DSP unit, it provides high-powered amplification in a 2U chassis, without onboard DSP processing.

Power Output & Amplification

• Four independent Class‑D amplifier channels
• Approximate maximum power per channel:
  • 500 W into 8 Ω
  • 1000 W into 4 Ω
  • 1400 W into ~2.7 Ω
  • 1200 W into 2 Ω
• Bridge mode options:
  • Up to 2000 W into 8 Ω
  • Up to 2400 W into 4 Ω
• Built for high-efficiency operation and capable of driving demanding loudspeaker loads reliably

Operation as a Slave Unit

• Operates paired with a Delta DSP-enabled “master” amplifier
• Receives control signals and audio via network or analog link
• Automatically enters standby mode until activated by the master unit over the GPI control line
• If the master fails or experiences a fault, the slave amplifies and seamlessly takes over output to maintain system continuity
  → Offers built-in backup protection for live applications
  → When master recovers, slave returns to standby status

Control & Interface

• Controlled via relay signal from the master amplifier over GPI
• No front-panel DSP editing required—routing, limiting, and DSP control handled by master
• Connects via analog inputs or optional Dante / network interface depending on configuration
• Speaker wiring must be connected to both master and slave to enable automatic switchover functionality

Typical Use Cases

• Acts as a power slave in stereo or multi-way systems under a Delta DSP master unit
• Systems where seamless failover protection is required (e.g. touring rigs, corporate events)
• Applications that require high channel density driven by remote DSP control
• Multi-zone audio configurations where controlled distribution of power is essential
