Setup: Episode EA-AMP-HYB-2D-1000/2000 Hybrid Amplifier User Manual

Overview

The EA-AMP-HYB-2D-1000/2000 Hybrid Amplifier is a two-channel DSP amplifier for distributed audio, stereo playback, and separate mono zones. Each channel can be configured for 70V or 8-ohm operation, while bridged mode combines the channels for a higher-power mono output.

This amplifier suits residential and commercial installations that require flexible speaker loads, independent source or volume control, network management, and integration with control systems. Balanced and unbalanced audio connections, digital connectivity, loop outputs, RS-232, Ethernet, and 12V trigger control support a wide range of system designs.

Detailed Description

The amplifier provides two independently configurable channels. A channel can drive 70V distributed loudspeakers or conventional 8-ohm speakers, provided that the selected output mode matches the connected speaker system. The hybrid design allows one channel to serve a 70V installation while the other operates with an 8-ohm load when the system configuration supports that arrangement.

Bridged operation is intended for installations that need one higher-power mono output. Speaker polarity is especially important in this mode, so follow the bridge markings beside the speaker terminals and verify the wiring before applying power.

The front panel combines a display, channel selection button, menu button, back button, and multifunction adjustment knob. The display communicates operating information and menu selections, while the knob adjusts levels and confirms selections. The rear panel provides the connection points required for source audio, speaker wiring, network control, serial control, trigger operation, and power.

Balanced inputs are suitable for sources that provide balanced line-level output. RCA inputs serve unbalanced sources. Both input types include corresponding loop outputs, allowing the audio signal to continue to another amplifier or audio component without requiring a separate splitter.

Safety

• Keep the amplifier away from rain, moisture, dripping liquids, and splashing. Do not place liquid-filled objects on top of the unit.
• Use the amplifier only with a properly grounded mains outlet. Do not defeat the safety function of the polarized or grounding plug.
• Maintain clear ventilation openings and install the unit according to the installation requirements. Do not place it near radiators, stoves, or other heat-producing equipment.
• Protect the power cable from being pinched, walked on, or damaged, especially near plugs and the point where it exits the amplifier.
• Disconnect the amplifier during lightning storms or whenever it will remain unused for an extended period.
• Disconnect the mains plug to completely isolate the amplifier from AC power. Keep the plug accessible after installation.
• Do not remove the cover. There are no user-serviceable parts inside; servicing must be performed by qualified personnel.
• Unplug the unit before inspecting connections, changing speaker wiring, or replacing the mains fuse.

Contents and Installation Tools

The package includes the amplifier, a detachable 6-foot IEC power cable, two rack-mounting ears, four removable feet, and a quick-start guide.

Installation is supported with a 2.0 mm slotted flathead screwdriver and wire strippers. Use 14- or 16-gauge stranded two-conductor speaker cable for typical speaker connections. Burial-rated cable is required where speaker wiring is installed outdoors or underground.

Setup and Operation

Front Panel Controls

• Display panel: Shows system information, menus, device details, and operating status.
• Channel Select: Selects the channel to adjust.
• Menu: Cycles through amplifier menus.
• Back: Returns to the previous menu level and can initiate reset procedures.
• Adjust/Set knob: Changes levels, scrolls through menu options, and confirms selections when pressed.
• Power button: Selects the amplifier’s operating or standby state.

Power and Network Control

The front-panel power indicator is blue when the amplifier is on and red when it is in standby. For network control, connect the RJ45 Ethernet port to a LAN. The amplifier can be managed through its local web interface, and compatible control-system or RS-232 drivers can be used for integration.

To view the amplifier’s IP address from the front panel, press the Menu button until the device-information screen appears, then turn the Adjust/Set knob. The network interface can be accessed by entering the displayed address in a web browser on the same network.

12V Trigger and Audio Sense

Apply 4.5–15V DC to the 12V Trigger In connection to turn the amplifier on. When the trigger voltage is removed, the amplifier returns to standby. The Trigger Out connection can pass the trigger signal to additional equipment or another amplifier for daisy-chain control.

When Audio Sense is enabled in the web interface, the amplifier wakes when it detects an audio signal. If no signal is detected for 15 minutes, it enters standby. Deep sleep is available for low-power operation but is not enabled from the factory.

Source Connections and Input Gain

Connect the source to a balanced terminal, RCA input, or supported digital input. Use the amplifier interface to select the input source, configure the pre-output, set gain, and adjust channel delay.

The input stage is optimized for a source voltage of 1.4 Vrms. If the source produces less voltage, increase input gain carefully to approach that level. Monitor the output meter while adjusting; a red level indication means the signal is clipping and the gain must be reduced.

For the most consistent control, keep the source output fixed and use the amplifier’s output level for volume adjustment. If the source controls volume instead, fix the amplifier output level and confirm that the source does not clip at its highest intended setting.

Speaker Connections

Connect each speaker cable to the correct positive and negative terminal, then tighten the terminal screws securely. Confirm that the output mode selected in the amplifier matches the connected loudspeaker system.

For 70V systems, the combined speaker wattage on a channel must remain within that channel’s rated output. For low-impedance operation, the connected system must not present less than 2 ohms to a channel. Recheck polarity and bridge-terminal wiring before powering the amplifier.

Volume Calibration

1. Connect the audio sources, speakers, and power cable.
2. Set available volume controls to their maximum positions.
3. Set each output-level control to approximately 50 percent, and reduce unused-channel input levels to minimum.
4. Turn on the amplifier and source, then play audio representative of normal use.
5. Set the source to about half volume. If the sound is distorted, lower the source level until it becomes clean.
6. Adjust the zone level slightly above the expected normal listening level.
7. If distortion remains, reduce the source or amplifier level and repeat the adjustment until the desired maximum level is clear.

Triad Audio Matrix Configuration

When a Triad Audio Matrix controls volume, set both amplifier channels to zero, play the zone at approximately 85–90 percent source volume, and raise the amplifier level until the desired maximum is reached. If the amplifier reaches its maximum output level, increase input gain as needed; a setting between 3 and 5 is a useful starting point, but the correct value depends on the source.

When the amplifier controls volume, set the matrix zone output to approximately 75–80 percent and disable loudness boost if enabled. Channel linking allows channel 1 control to maintain the configured level relationship with channel 2. Gain should not exceed 7 in this configuration.

Speaker Presets

The amplifier includes presets combining output configuration and DSP settings for compatible landscape speaker systems. Presets are available for LS-SAT-4, LS-SAT-6, and LS-SAT-8 speakers in 70V and 8-ohm versions, including combinations with LS-HSUB-10 and LS-BSUB-12 subwoofers.

The factory preset bank includes a flat 8-ohm default and presets numbered 2 through 19 for satellite-only, hardscape-subwoofer, and burial-subwoofer combinations. Preset names identify the speaker arrangement and output mode, such as LS4SATS, LS6SAT_8, ST4_HS10, and S4SB12_8.

Loading a Preset from the Front Panel

1. Press the Menu button.
2. Turn the Adjust/Set knob until the preset menu appears, then press the knob.
3. Turn the knob to the desired preset and press it. The display shows the preset name with a load option.
4. Press the knob again to load the preset.

Loading a Preset through the Web Interface

1. Open the Preset page.
2. Choose a preset from the selection list.
3. Select Load Preset.

To import a preset file, use the Import Preset function and refresh the interface afterward. Importing replaces the existing preset list. Use Reset Presets to restore the amplifier’s factory preset bank.

Additional preset groups support mixed LS-SAT models between channels and combinations with LS-BSUB-8 or LS-BSUB-10 subwoofers. Select the group that matches the exact speaker models, impedance, channel assignment, and output mode.

Resetting the Amplifier

With the amplifier powered on, press and hold the Back button for 10 seconds to perform a soft reset. This clears login information without resetting the complete audio configuration.

Press and hold the Back button for 20 seconds to perform a factory reset. The front-panel indicators flash during the process. A factory reset clears DSP settings, channel levels, input names, and other stored configuration data. If the reset does not respond, update the firmware to version 1.3 or later when possible. If the Back button procedure remains unavailable, the same reset timing can be attempted with the Menu button.

Troubleshooting

Protection Indicator Blinks Red

• Possible cause: Excessive temperature. Action: Allow the amplifier to cool; protection should clear automatically.
• Possible cause: The output is demanding more power than its rating. Action: Reduce the music level to release the speaker-protection limiter.
• Possible cause: Firmware is updating. Action: Allow the update to finish, especially when both channel indicators blink.

Protection Indicator Remains Red

A solid red indicator can indicate a short at a speaker terminal. Disconnect the speaker terminal and inspect the wiring, conductor strands, polarity, and terminal connections. Channel 2 may indicate a short detected on either terminal. If the indicator remains solid after the terminal is removed, the amplifier requires further service diagnosis.

No Audio Output

If the front-panel or web-interface level meter responds, the amplifier is receiving audio. Confirm that the speaker output mode is correct, then verify the selected source, input wiring, channel assignment, and speaker-terminal connections. If the meter does not respond, troubleshoot the source and input selection first.

Distortion at Normal Listening Levels

Excessive amplifier level used to compensate for a low source signal can create hiss, hum, clipping, or harsh high and low frequencies. Return the source and amplifier controls to baseline settings, then recalibrate so the intended maximum listening level remains clean.

Thump from an Inline Volume Control

A thump can occur when the amplifier and source levels are both too high. Calibrate the inline control so normal listening occurs one or two steps below its maximum setting, leaving additional adjustment range for occasional louder playback.

Warranty

The product includes a limited warranty. Coverage details and duration are defined by the applicable warranty terms supplied for the amplifier.
