Russound ADP-1.2 Speaker-level to Line-level Adapter

1. Product Overview

The Russound ADP-1.2 is a speaker-level to line-level adapter designed to convert high-level speaker outputs from an amplifier into low-level line outputs. This allows for connection to devices that require a line-level input, such as external amplifiers or subwoofers, especially in systems where the primary amplifier lacks dedicated pre-amp outputs.

It is specifically recommended for use with Russound CAA66 and MCA-66 systems to obtain line-level outputs for zones without pre-amp outputs. The unit features color-coded detachable 14-gauge snap connectors for easy installation.

2. Important Safety Information

• WARNING: This device is NOT FOR USE WITH DIGITAL AMPLIFIERS. Connecting to digital amplifiers may result in damage to the adapter or the amplifier.
• Always disconnect power to audio equipment before making any connections.
• Ensure all connections are secure to prevent short circuits.
• Do not expose the unit to moisture or extreme temperatures.
• Do not attempt to open or modify the unit. There are no user-serviceable parts inside.

3. Package Contents

Verify that all items are present in the package:

• Russound ADP-1.2 Speaker-level to Line-level Adapter unit
• Detachable 14-gauge snap connector (pre-installed on unit)
• Mounting brackets (integrated into the unit's design)

4. Setup and Installation

Follow these steps to properly install the ADP-1.2 adapter:

1. Power Off: Ensure all audio equipment, including the amplifier and any connected devices, is powered off and unplugged from the AC outlet.
2. Identify Speaker Outputs: Locate the speaker-level outputs on your amplifier or receiver that you wish to convert to line-level.
3. Connect Speaker Wires: Connect the speaker wires from your amplifier's speaker outputs to the color-coded detachable 14-gauge snap connector on the ADP-1.2.
   • Match positive (+) and negative (-) terminals correctly.
   • Ensure wires are securely inserted into the snap connector.
4. Connect Line-Level Outputs: Connect RCA cables (not included) from the RCA outputs (JK1 LEFT, JK2 RIGHT) on the ADP-1.2 to the line-level inputs of your external amplifier, subwoofer, or other audio device.
5. Mounting (Optional): The ADP-1.2 features integrated mounting brackets. Secure the unit in a suitable location using appropriate screws (not included), ensuring good ventilation and accessibility for connections.
6. Power On: Once all connections are secure, plug in and power on your audio equipment.

5. Operating Instructions

The Russound ADP-1.2 operates passively, converting the high-voltage speaker signal into a low-voltage line-level signal without requiring external power. Once connected, it functions automatically:

• Audio signals from your amplifier's speaker outputs are fed into the ADP-1.2.
• The adapter attenuates and converts these signals into a standard line-level output.
• The line-level signals are then available at the RCA outputs for connection to other audio components.
• No user adjustments or controls are present on the unit.

6. Maintenance

The ADP-1.2 is designed for reliable, maintenance-free operation. To ensure longevity:

• Keep the unit clean by wiping it with a soft, dry cloth.
• Avoid using liquid cleaners or solvents.
• Ensure proper ventilation around the unit to prevent heat buildup.
• Periodically check all connections to ensure they remain secure.
