LS2 and LR2 Balanced Audio Sender/Receiver

The Sonance LS2 and LR2 form a system designed to send low-level audio signals long distances and in close proxim- ity to sources of noise interference without inducing noise or high-frequency roll-off. As a general rule of thumb, a balanced signal should be used for anything but short lengths of audio cable (under 20 feet) and wherever the possibility of signal interference is likely (i.e. where the audio signal passes near dimmers, transformers, fluores- cent or neon lights, or along the same pathways as house current). The active LS2 circuitry converts the unbalanced signal to a balanced configuration and sends the balanced signal to the LR2, which conver ts it back into an

unbalanced signal. This virtually eliminates any noise picked- up over the length of the wire, leaving only the original signal.

The LS2 and LR2 are always used in conjunction with each other, except when used in conjunction with equipment with balanced inputs or outputs (such as professional sound or recording equipment). In this type of system the LS2 serves as an unbalanced-to-balanced converter and the LR2 serves as a balanced-to-unbalanced converter. The LS2 can also be used with the 275 SE and ASAP2 SAT amplifiers fitted with an LR1 SAT module (part# 91815).

Features:

• The LS2 unbalanced input and LR2 unbalanced output

connectors are high-quality gold-plated RCA connectors.

• The LR2 balanced input and LS2 balanced output connectors

are removable quick-toggle RIA connectors.

• The LS2 and LR2 operate on a single-output 12V DC

power supply (included with both units), and can also be

powered directly by 12V sources. The power inputs have

reverse-polarity protection.

• DC In and DC Out connections on both units allow the

installer to power multiple units from a single power supply.
