Crown 1160ma 仕様ガイド

he Xs Series of power amplifi ers from 
Crown

®

 represents a new era in afford-

able, quality power amplifi cation. The line 

consists of four models in a uniform, rugged 2U 
chassis, incorporating the best of tried-and-true 
design principles and innovative features.

The four models in the series are the Xs500, 
Xs700, Xs900, and Xs1200. They are identical 
to the user except for output power. 

Xs Series amplifi ers are professional stereo 
power amplifi ers engineered to meet demand-
ing audio requirements—reliably and within 
budget. Every Xs Series amplifi er is backed by 
Crown’s unequaled Three-Year, No-Fault, Fully 
Transferable Warranty.

With over fi ve decades of experience designing 
and building rock-solid products, Crown is the 
standard in amplifi er technology.
