This document describes the Episode Hybrid Amplifier models EA-AMP-HYB-2D-1000 and EA-AMP-HYB-2D-2000, which are two-channel amplifiers designed for various audio applications.
Function Description
The Episode Hybrid Amplifier is a two-channel amplifier capable of operating with either 70V or 8 ohm loudspeakers, with selectable output modes for each channel. It supports two-channel stereo audio or two mono zones with different sources or levels. Channels can also be bridged to increase output power and send a singular mono signal. The amplifier is optimized for peak performance when the input voltage of the source is 1.4V, and includes a pre-amplified stage to modify the input source voltage if it is less than 1.4V.

Usage Features
IP/OvrC Control:
The amplifier can be connected to a LAN for OvrC control. Users can create an account on www.OvrC.com, add the device using its MAC address and serial number, and follow setup directions. The local UI can also be accessed via a web browser by entering the amplifier's IP address (displayed on the front panel). Default login credentials are username: episode, password: episode.
Front Panel Controls:
- Display Panel: Shows system information.
- Channel Select: Press to select the input channel.
- Menu Select: Press to cycle through system menus.
- Back Button: Navigates back one step in the system menu.
- Level Adjustment/Selection Knob: Turns to adjust system levels, presses to select.
- Power Switch with LED Indicator: Momentary switch for manual control of standby power mode (Blue for On, Red for Standby).
Rear Panel Connections:
- Ethernet Port (RJ45): For IP control.
- RS-232: For communication with a control system or PC.
- 12V Trigger IN and OUT: Allows the amplifier to turn on/off with a 4.5-15V DC signal and control other equipment.
- Balanced Inputs 1 & 2: Set-screw connections for balanced sources.
- Unbalanced Inputs 1 & 2: RCA input connections for unbalanced sources.
- Unbalanced Loop Out 1 & 2: RCA loop out for connecting to other amplifiers.
- Balanced Loop Out 1 & 2: Set-screw balanced loop out for connecting to other amplifiers.
- Digital Input/Output Ports: For digital sources.
- Speaker Terminals: Screw terminals for speaker connections, with markings for bridge mode.
- Main Power Switch: Main amplifier power switch.
- IEC Power Cord: Detachable power cable.
- AC Fuse: Replaceable main power fuse.
Speaker Connections and Output Mode:
Use 14 or 16 gauge stranded two-conductor speaker wire. Connect to screw terminals, observing polarity. Bridged markings are provided. Burial-rated wire should be used for outdoor applications. Output mode (8 Ohm, 70V, 100V) can be configured via the web interface.
Amplifier Power Control:
- 12V Trigger: Amplifier turns on when 4.5-15V DC is applied to 12V IN and turns off when voltage drops. 12V OUT allows daisy-chain control of other equipment.
- Audio Sense: If enabled via the web interface, the amplifier turns on when an audio signal is detected and enters standby after 15 minutes of no signal.
- Power State: Supports Deep vs. Light Sleep modes. Deep sleep is required for EU low power consumption standards when the amplifier is not operational (not enabled out of the box).
Volume Calibration:
To calibrate source input gain and inline volume control:
- Connect all speakers and audio sources, then power on the amplifier.
- Set all volume controls to maximum (if applicable).
- Set each output level adjustment knob to 50% and unused input levels to minimum.
- Power on the amplifier and input source, play typical audio.
- Set source volume to half; if distorted, reduce until clear.
- Adjust the level for the area slightly above normal listening level; if distorted, adjust source volume and LEVEL knob until clear.
Speaker Presets:
The amplifier comes with preloaded presets for various landscape speaker configurations, including full system presets and DSP settings for use with ES-LS-BSUB-12 or ES-LS-HSUB-10 subwoofers. Subwoofers must be connected to Channel 1 when using these presets. Additional preset files (Preset Group B and C) are available on the product's Support tab for mixing different LS-SAT models between channels or for use with ES-LS-BSUB-8 or ES-LS-BSUB-10.
Using Presets:
- Local Display: Press Menu, rotate Adjust/Set to "Menu Preset", press, rotate to desired preset, press to load.
- Web Interface: Click "Preset" button, select from drop-down list, click "Load Preset".
- Loading Preset Files: Click "Import Preset", choose file, click "Load". Refresh the page for new presets. Loading a preset file erases current listings; "Reset Presets" restores defaults.
Maintenance Features
Resetting the Amplifier:
- Soft Reset: Press and hold the BACK button for 10 seconds after power-on to reset login information.
- Factory Reset: Press and hold the BACK button for 20 seconds to reset all settings including DSP, channel levels, and input names. Front panel lights will flash during the process.
Troubleshooting:
- Going into Protection (Red Protect LED Blinking):
- High Temperature: Allow unit to cool down.
- High Current: Reduce input music level.
- Firmware Updating: N/A, allow update to finish.
- Going into Protection (Red Protect LED Solid):
- Speaker Terminal Short: Ensure speaker terminal is fully connected. Remove speaker terminal; if light is still solid, investigate further.
- Failure to Jump to Partition after Firmware Update: Contact Tech Support for firmware recovery.
- No Output (Level Meter LEDs/WebUI):
- Level Meter (Green LED) Illuminates: Ensure speaker output is configured correctly.
- Level Meter in Web UI is Responsive: Ensure source inputs are configured correctly.
Distorted Audio at Normal Volume:
If the LEVEL adjustment is too high for low source volume, distortion (background noise, clipping, etc.) can occur. Re-adjust volume levels starting at baseline settings, ensuring maximum comfortable volume without distortion using source volume or inline control.
Inline Volume "Thump":
If a "thumping" sound is heard, amplifier and source volume levels are too high. Calibrate inline volume controls to be one or two adjustment levels away from maximum at normal listening level, allowing for extra volume if needed.
