1969 OPERATORS’ MANUAL2

INTRODUCTION

The 1969 is a hybrid vacuum tube/semi-conductor, dual-channel compressor which has
numerous applications in studio recording, live sound, location recording, post­production and as part of a musician's rack system.

The microphone input stages feature extremely low noise, balanced input circuitry with
additional tube amplification, enabling modern microphones to take on the
characteristics of older tube models.

APPLICATIONS

" General studio compressor
" Complete stereo mixes.
" For high quality location recording, the 1960 makes the perfect partner for

a DAT machine, as it combines the functions of stereo mic preamp with
that of a compressor.

" The mic inputs provide up to 60dB of gain.
" As an instrument amplifier, the 1969 provides gain, EQ and compression,

providing the type of overdrive sound associated with tube guitar
amplifiers.

" When the compressor is overdriven, it can be used creatively on electric

guitar or rock vocal sounds.

" The Aux input may be used for processing the output from a dedicated

guitar preamplifier, where the EQ can be used to further tailor the sound
before it is compressed.
