Episode EA-COM-AMP-4D-80 4-Channel 70V/100V DSP Amplifier

Power and Control Four Speaker Zones from One Compact Amplifier

The Episode EA-COM-AMP-4D-80 is a four-channel Class D DSP amplifier with selectable 70V, 100V, 8-ohm, or 4-ohm output on each channel. It is a flexible choice for multi-zone music, paging, speech, and distributed speaker systems that need independent routing and tuning.

Power and Speaker Compatibility

• 4 amplified output channels
• 80W RMS per channel into 4 ohms
• 80W RMS per channel into 8 ohms
• 80W RMS per channel in 70V mode
• 80W RMS per channel in 100V mode, specified at approximately 90-92Vrms
• 320W RMS maximum system output for 5 seconds at 1 kHz
• 20 Hz to 20 kHz frequency response, ±2 dB

Each channel can be configured independently for 70V, 100V, 8-ohm, or 4-ohm operation. Do not mix different speaker-system types on the same output channel.

70V and 100V System Planning

For 70V or 100V speakers, add the transformer tap wattage of every speaker connected to that channel. Keep the total speaker load below the amplifier's 80W RMS channel rating and leave appropriate headroom for reliable operation.

Transformer tap settings are selected on the speakers, not on the amplifier.

DSP and Matrix Routing

• Fully matrixed source routing
• 10-band parametric EQ
• Low- and high-shelf filters
• High-pass and low-pass crossover filters
• Compression
• Up to 50 ms adjustable audio delay
• 32 Episode speaker presets
• Mono input summing
• User-selectable priority input

MaxShare Power Technology

MaxShare allows paired amplifier channels to share available power when one channel needs more output than the adjacent channel. System design should still account for the total available amplifier power and the requirements of every connected speaker load.

Inputs and Control

• 4 balanced line-level analog inputs
• Gigabit Ethernet connection
• Local web-based configuration
• IP control
• OvrC remote management
• Control4 SDDP support
• User-configurable 2-pin contact-closure input
• Analog input signal sensing

Ethernet is used for configuration, control, and monitoring. Bluetooth, Wi-Fi music streaming, and built-in streaming services are not included.

How many channels does the EA-COM-AMP-4D-80 have?

It provides four independently configurable amplified output channels.

How much power does each channel provide?

Episode specifies 80W RMS per channel into 4 ohms, 8 ohms, 70V, or 100V, including with all four channels driven.

Does it support both 70V and 100V speakers?

Yes. Each channel can be configured for 70V, 100V, 8-ohm, or 4-ohm operation. Episode specifies its 100V mode at approximately 90-92Vrms.

How do I calculate a 70V speaker load?

Add the selected transformer tap wattage of every speaker connected to the channel. Keep the total below the 80W RMS channel rating and leave suitable amplifier headroom.

Does it have built-in DSP?

Yes. DSP includes 10-band parametric EQ, shelf filters, crossover control, compression, delay, speaker presets, priority input settings, and mono summing.

Can different sources be routed to different channels?

Yes. Fully matrixed routing allows connected analog sources to be assigned to different amplifier outputs.

Does it include Bluetooth or Wi-Fi streaming?

No. Bluetooth and built-in music streaming are not included. A separate audio source or streamer is required.

Does it support IP control and OvrC?

Yes. Its Gigabit Ethernet connection supports local web configuration, IP control, OvrC management, and Control4 SDDP.

Does it work with the EA-COM-WP-ZONE wall controller?

No. Episode specifically states that the EA-COM-AMP-4D-80 is not compatible with the EA-COM-WP-ZONE wall controller.

Can it be installed outdoors?

No. Install the amplifier indoors in a dry, ventilated equipment location.

What should I confirm before ordering?

Confirm your speaker type, impedance or transformer taps, number of zones, required wattage, source connections, network setup, and control requirements.
