Crest Audio IPA-2300

The Crest Audio IPA 2300 is a 2-channel, 300-watt Class D mixer-amplifier built for background-music and paging systems in retail, restaurant, and waiting-room installations. Input 1 accepts a balanced mic or line signal over a Euro connector, while Input 2 takes a line-level source through dual RCA jacks; a level-sensing circuit automatically mutes Input 2 whenever the mic signal on Input 1 rises above an adjustable threshold, so a page always cuts through background music without the installer needing a separate mixer. The amplifier drives 4Ω direct loads or 25V/70V/100V constant-voltage speaker lines from the same output.

Key Features

• Automatic mic-priority muting: Input 2 mutes when Input 1's mic/line signal exceeds an adjustable (or defeatable) threshold
• Selectable output: 4Ω direct or 25V/70V/100V constant-voltage speaker lines
• SPS speaker protection and a high-pass filter that guards speaker transformers from low-frequency overload
• Bass and treble tone controls
• Dual-voltage 120/240VAC operation
• 2U rack-mount chassis with power, signal, and SPS status LEDs
