Combine Music and Paging in One Compact Audio System

The Episode ECA-70MIXAMP-1-120D is a single-channel 120W RMS Class D mixer amplifier for 70V distributed speakers or conventional 4–16-ohm speaker loads. Built-in Bluetooth, microphone mixing, priority audio, and front-panel controls make it easy to combine background music and announcements.

Power and Speaker Compatibility

• 120W RMS mono output
• Selectable 70V or 4–16Ω speaker output
• Class D amplification
• Frequency response: 50 Hz to 16 kHz

For a 70V system, add the selected transformer tap wattage of every connected speaker. Keep the total below 120W and leave amplifier headroom. A practical target of about 96W or less provides approximately 20% headroom.

This model does not provide a 100V speaker output.

Bluetooth, Microphone, and Audio Inputs
