Introduction

Thank you for purchasing a Yamaha XH150 power amplifier.

The development of the XH150 was enriched by Yamaha's wealth of experience in building

PA equipment and its tradition of precision circuit design technology. This amp is dedicated

to driving high-impedance speakers, and feature high power and superb quality together with

superior reliability and stability, guaranteeing the highest possible audio performance.

Main features of the XH150:

• The unit is equipped with two types of inputs (balanced XLR and barrier strip) and one

barrier strip output.

• The voltage line is switchable between 100 V and 70 V, and output is rated at 150 W.

The high-impedance design makes the unit most suitable for driving multiple speaker

systems simultaneously in a facility.

• Independent low-cut/high-cut filters are provided for channels A and B. These filters

allow you to change cut-off frequencies.

• A SIGNAL indicator and CLIP indicator is provided for each channel.

• The PROTECTION indicator shows the status of protective circuitry such as power-on/

off protection, output muting, and the DC detection circuit.

• Variable-speed low-noise fan(s) ensures high reliability even under demanding condi-

tions.

In order to take full advantage of your XH150 and enjoy long and trouble-free operation,

please read this owner's manual carefully before use.
