TX-LC2

RDL TX-LC2 - Unbalanced to Balanced Line Combiner with Mono Output

RDL TX-LC2 is a compact module designed to actively mix two unbalanced line-level audio sources into a single mono output, which can be either balanced or unbalanced. It’s ideal for AV installations requiring stereo-to-mono conversion or combining two separate sources into one clean audio feed.

The TX-LC2 features an active summing amplifier with adjustable gain and transformer-isolated output, ensuring high-quality audio and separation between inputs. The 150Ω output driver supports both high and low impedance lines, making it suitable for professional and consumer-grade equipment.

Functionality

• Mixes two unbalanced line-level signals into a mono output
• Converts unbalanced input to balanced output
• Combines stereo sources into mono without affecting channel separation
• Adjustable output gain from -10 to +10 dB
• Transformer-isolated output - protects against interference
• Supports -10 dBV input levels – ideal for consumer devices
• Operates on 24V DC or 12V DC (with reduced headroom)

Features

• Active summing mixer - ensures clean and stable audio performance
• High-impedance inputs - maintain stereo integrity
• 150 Ω output impedance - compatible with professional audio standards
• Compact TX-series enclosure - easy integration into AV systems
• Terminal block connectors - secure and fast installation
• Suitable for AV, education, broadcast, exhibitions, and commercial systems

RDL TX-LC2 is a reliable solution for AV integrators, offering professional-grade mixing and conversion of unbalanced audio sources into a balanced mono output.
