AVENTAGE Separate Components.

NEW PRODUCT BULLETIN

CX-A5000

11.2-channel AV Pre-Ampliﬁ er

Yamaha is proud to introduce two ﬂ agship separate components that stand at

he pinnacle of the AVENTAGE Series of ultra-high performance components.

They are the fullest expression of the AVENTAGE concept, which combines

ne craftsmanship, superb sound quality, unequalled sound realism,

nnovative technologies and enhanced controlla

of uncompromising design and technological integrity manifested by our Z11

agship receiver, the CX-A5000 and MX-A5000 take the AVENTAGE Series to

new levels of audio performance, as well as greater than ever ﬂ exibility for use

n network environments. By delivering not only great sound quality but also the

ability to achieve the best possible performance from any source, they take

he home theatre experience to a new standard of excellence and enjoyment

Overwhelming Power and High Density Presence Achieved by 11.2-channel Separate AV Am

Making full use of Cinema DSP H pinnacle of 3-dimensional sound ﬁ eld

eproduction, the CX-A5000 AV Pre-Ampliﬁ er ealises detailed, accurate sound imaging.

The MX-A

orce that provides superb quality and performance for all channels. Combining these two achieves overwhelming silence and sound

lled with dynamic feeling, the goal to which Yamaha constantly aspires. With all types of

ound sources, you w that immerses you in music with the full scale presence of 11.2 channels.

Specially Designed High Rigidity Chassis Eliminates the Effects of Vibration for Greater Sound Purity

As part of the no-compromise design policy

or these two ampliﬁ ers, Yamaha created an

dvanced chassis with strong rigidity. Chassis tiffness is enhanced by an H-shaped cross

rame that boosts mechanical strength, by

dopting aluminum side panels that increase

the st

ness of the housing, and by a three-ply tructure with ind anels. Any external vibration from the rack

other sources is damped by heavy insulators.
