Front panel

  1. Power LED — Indicates the power status.

    • Solid Blue: On or Standby mode.

    • LED off: No power detected.

  2. Display — Displays system information and configuration menus. Read the Front Panel Display section for more information.

  3. Volume adjustment/Selection knob — Turn to adjust the volume level or change the displayed menu selection. Press to make a selection.

Rear panel

  1. Digital input and output ports (coax) — Connections for digital sources. The Output port passes the input signal through to additional amplifiers.

  2. Unbalanced analog input (stereo RCA) — Unbalanced RCA input for connect line-level analog sources.

  3. Unbalanced analog loop-through (stereo RCA) — Unbalanced RCA output to pass the analog input signal to additional amplifiers.

  4. Balanced analog inputs (phoenix) — Balanced output that passes a balanced analog input signal through to additional amplifiers.

  5. Balanced outputs (phoenix) — Balanced output that passes a balanced analog input signal through to additional amplifiers.

  6. RJ45 input — A 10/100 Ethernet port for IP control, remote management, and web interface configuration of amplifier. This port provides an LED indicator for when it's active. It does stay active in Standby mode.

  7. Rest button — A recessed button with the following functions:

    • Quick press — Restarts the amplifier.

    • Hold for 5 seconds — Resets the network settings to DHCP.

    • Hold for 10+ seconds — Resets the amplifier to the factory default settings.

  8. Power switch — Turns the amplifier on/off.

  9. Speaker output terminals (phoenix) — Accepts up to 12 AWG speaker wire. Note the polarity when bridging speakers.

  10. IR status LED — Illuminates when an IR signal is received.

  11. IR power on/off switch — If on, +12V DC is applied to the IR IN port to provide power for an external IR receiver.

    Caution: Do not turn IR power on if there's a direct IR connection to a control system.

  12. IR input/output connections — 3.5 mm connections for an IR input or output from another device. The IR output passes the incoming signal through to additional devices.

  13. 12V trigger input/output connections — 3.5 mm connection for a 12V trigger input from another device. The amplifier powers on when 4.5-15V DC is applied. When the voltage drops below 4.5V the amplifier turns off. The 12V trigger output supports other devices to be controlled from the same 12V signal.

  14. Power input — Input for 3-prong IEC power cord.

    Note: The EA-HYB-AMP-2D-2400 requires a 20A power cable and circuit in North America.
