RTI AMP4-125 4-Channel 125W DSP Matrix Amplifier

The RTI AMP4-125 is a 4-channel DSP matrix amplifier built for multi-zone background music and paging installs, pairing directly with RTI control processors for full audio distribution and control from one ecosystem.

Four analog audio source inputs (balanced or unbalanced) plus a digital S/PDIF input feed a built-in DSP matrix, with flexible output configuration: two Lo-Z stereo zones, four Lo-Z mono zones, two Hi-Z (70V/100V) mono zones, or a mix of all three. The Class D amplifier delivers 125W per channel at 4Ω/8Ω, or 250W per channel at 70V/100V line level, and multiple units can be daisy-chained to expand zone count further.

• 4 analog audio inputs (balanced/unbalanced) + 1 digital S/PDIF input
• Flexible zone output: 2 Lo-Z stereo, 4 Lo-Z mono, 2 Hi-Z (70V/100V) mono, or mixed
• Class D amplification: 125W @ 4Ω/8Ω per channel or 250W @ 70V/100V per channel
• Built-in DSP for per-zone acoustic tuning
• Daisy-chainable for expanded zone counts
• Integrates directly with RTI control systems
