Introduction

Thank you for your purchase of the YAMAHA T5n, T4n, T3n Series Power Amplifier.

This series of power amplifiers was developed from Yamaha’s wealth of experience in building PA equipment and its tradition of careful attention to every detail of circuit design. These power amplifiers feature high power — thanks to EEEngine (Energy Efficient Engine) technology — and superb quality together with superior reliability and stability, guaranteeing the highest possible audio performance.

Features:

Three modes are provided to support a broad range of applications: STEREO mode which can be driven by two independent sources, PARALLEL mode in which a monaural source drives both channels, and BRIDGE mode in which the two internal amps function as a single high-power mono amp.

Balanced XLR connector and Euroblock connector inputs, and Speakon connector and five-way binding post outputs are provided.

SIGNAL indicator, CLIP indicator and MUTE indicator and sophisticated dB step Volume control are provided for each channel.

PROTECTION indicator that shows the state of various protection systems (power On/Off detection, output protection, DC detection), a TEMP indicator that indicates heat sink overheating, and a POWER/STANBY indi- cator that indicates the power status are provided.

Variable-speed low-noise fans ensure high reliability.

The T5n enables parallel connection of multiple high-impedance speakers that support 100 V line output.

The T3n enables parallel connection of multiple high-impedance speakers that support 70 V line output.

An optional external amp control unit, such as the ACU-16C, enables you to monitor or control the amplifier via a network. For the latest information about amp control units, please visit our website:
