INTRODUCTION 

The On-Q/Legrand lyriQ™ Triple-Source Input (P/N AU7428) converts 
and sends line-level audio from up to three audio components (i.e. 
Stereo Receiver, CD Player, Tape Deck, etc.) to an audio distribution 
module via Category 5 cable (see 

Figure 1

).  

It is an integral part of the lyriQ™ Audio System, which utilizes 
Category 5 technology to distribute high quality audio to remote 
locations via Category 5 cable, creating a versatile whole-house audio 
system that will fill your rooms with high quality sound for years to 
come. This technology provides many advantages over conventional 
methods of audio distribution, such as simple Category 5 wiring 
schemes, infrared control of system components, and improved sound 
quality due to an amplifier being located in every room. 
This unit also receives IR control codes from the Volume Control IR 
Targets and passes them to the emitter output ports for control of the 
source equipment.

DESCRIPTION 

The lyriQ™ Triple-Source Input typically resides at the entertainment center (see 

Figure 2

). It accepts stereo line level audio via three 

sets of Left/Right RCA jacks, and transmits the audio via two Category 5 cable runs to a centrally-located, enclosure-mounted lyriQ™ 
Four Source, Eight-Zone Distribution Module (P/N AU1002). The distribution module then distributes the audio, also via Category 5 
cable, to lyriQ™ Amplified Keypads (P/N AU7394-xx or AU5009-xx for Studio version) or lyriQ™ High Performance Keypads (P/N 
AU1000-xx or AU5010-xx for Studio version) in multiple rooms throughout the house. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

  If an audio component is being shared with an 

A/V receiver and the multi-source system, and 
doesn't have secondary fixed stereo line level 
outputs, use two Y-cables to split that 
component's output signal so it can be sent 
directly into one set of RCA jacks on the Triple-
Source Input and also to the A/V receiver (see 

Figure 3

).
