DIMENSION D

The SDD-320 Dimension Dis aspecial-

ly designed chorus effect unit for add-

ing spatial effects to stereo and

monaural sound sources. Monaural in-

puts are converted from asingle point

Dgives anew dimension without the

apparent movement of sound produced

by most other chorus devices.

FEATURES

•Both balanced and unbalanced in-

puts and outpuSs for ease of use in the

studio or on the stage,

•Click-free noisless switching between

four different dimension modes.

•Remote controlled dimension EF-

FECT/NORMAL function.

•Fast acting LED level indicators,

•Low noise (S/N greater than 95dB,

"A" weighted)

•Standard 19" rack mounL
