1. OVERVIEW

Welcome to purchase the equipment by AC-audio!

The equipment is a signal processor that utilizes both valve and transistor technology.

The audio processing units of equipment can support high quality signal paths, produce

the particular valve audio peculiarity by adopting low noise solid-state electronic

components and perfect valve circuitry. It has the comprehensive and various functions

on controlling sounds, offering users clear, exquisite and high-quality sound.

There are a single balanced mic input and stereo line inputs/outputs on the rear panel,

and stereo instrument inputs on the front panel. The two channels of the equipment work

in'linked stereo' mode, but a mono signal can be applied to channel 1 only, thus can offer

the equipment equally powerful for both mono/stereo tracking and final stereo mix

processing. Two illuminated VU meters monitors the both channels for output level.

To satisfy the requirement of performance that low noise, low distortion and wide

bandwidth should be needed, electronically balanced input amplifier appeared. The

preamp stage utilizes 48V phantom power and a high pass 90Hz filter. A Drive LED gives

a visual indication of the signal level through valve stages, monitors the amount of

'warming' taking place. The Peak LED warns that overloading is going to be happened.

The Mic input of equipment is provided on an electronically balanced XLR connector,

and the line inputs are provided on balanced TRS stereo 0.25" jack connectors.

Balanced and unbalanced line outputs can be used at the same time, and they are

provided (again on TRS 0.25" jack connectors). The operating level of both the line input

and outputs can be shifted from -10dB to +4dB via a rear panel switch, allowing the

equipment to integrate into any system easily. On the front panel, without the need for a

separate DI box, a pair of high impedance instrument inputs allows keyboards, guitars

and basses to feed into the equipment directly.
