Memphis LL2L 2-Channel Line Output Converter

The Memphis LL2L is a 2-channel line output converter designed to add preamp-level RCA outputs to a factory or aftermarket car audio system. It provides an interface for sending audio signal from speaker-level wiring to an external amplifier. This makes it a practical component for upgrades that retain the original radio.

Built for OEM-system integration, the LL2L supports OEM load detection to help maintain the load expected by compatible factory audio systems. Its differential balanced inputs and low-impedance outputs are designed for stable signal transfer. The result is a converter focused on clean signal routing between the source unit and amplifier.

Variable gain adjustment allows the output level to be matched to the connected amplifier. An integrated LED clip indicator helps identify when the signal level is approaching clipping during setup. This gives installers a visual reference when setting the converter's output.

The LL2L includes selectable DC-offset and audio-detect turn-on options for systems without a conventional amplifier remote lead. It also generates a +12V remote output for activating a connected amplifier. These functions can simplify integration with compatible factory radios.

Its compact aluminum chassis is intended for installations where available space is limited. Locking detachable power and speaker terminals help keep wiring secure, while panel-mount RCA jacks provide a fixed connection point for signal cables. With up to 11V of preout voltage, the LL2L is suited to two-channel amplifier integration or as a signal source for an expanded audio system.

Key Features

• Two-Channel Conversion: Provides two channels of line-level output for amplifier integration.
• OEM Load Detection: Supports compatible factory systems that require load detection.
• Differential Balanced Inputs: Designed to accept balanced speaker-level input signals.
• Variable Gain Control: Allows output level adjustment to match the connected amplifier.
• LED Clip Indicator: Gives a visual reference while setting signal level.
• Selectable Turn-On: Offers DC-offset or audio-detect activation with generated +12V remote output.

Design & Installation

The LL2L uses a compact aluminum chassis with locking detachable power and speaker terminals. Its panel-mount RCA jacks are designed to provide a secure, fixed signal connection. The compact enclosure measures 2.76 inches wide, 2.85 inches long, and 1.10 inches high.

Install the converter between compatible speaker-level source wiring and the RCA inputs of an external amplifier. Select the appropriate DC-offset or audio-detect turn-on method for the vehicle, then use the variable gain and LED clip indicator during level setup. The generated +12V remote output can be used to trigger a compatible amplifier.
