Operating Manual - LX-308B Stereo Line/Microphone Mixer

INTRODUCTION

Congratulations on your purchase of an Ashly LX-308B eight channel stereo line level mixer. Each channel has on/off

switches and peak signal detection. Other features include eight balanced stereo inputs for line level sources, the first two inputs

with switchable 30dB gain for low impedance dynamic microphones. An additional 3.5mm front panel input jack is provided on

channel 8 for a walk-up portable audio player input. A concentric level and pan control for each input adjusts channel volume

and stereo position. Submaster inputs and outputs are provided for cascading two or more mixers. Ultra low-noise summing

amplifiers combine the channel signals for the main outputs. A pair of 6-segment LED meter arrays monitor the main output

levels. Separate level controls are provided for stereo, mono, and headphone outputs.

UNPACKING

Every Ashly product is carefully inspected before leaving the factory to ensure flawless appearance. After unpacking,

please inspect for any physical damage. Save the shipping carton and all packing materials , as they were carefully designed to

reduce to minimum the possibility of transportation damage should the unit again require packing and shipping. In the event that

damage has occurred, immediately notify the carrier so that a written claim to cover the damages can be initiated. The right to

any claim against a public carrier can be forfeited if the carrier is not notified promptly and if the shipping carton and packing

materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.

AC POWER REQUIREMENTS

This LX-308B mixer has a universal AC power supply that will perform normally from 100 to 240 volts AC. Use only

properly grounded AC receptacles. To reduce the risk of ground loop hum, use a central point for system AC power distribution.

The AC line fuse is internal, and should only be changed by a qualified service technician.

SECURITY COVERS

For installations where it is desirable to protect the front panel controls from tampering or accidental misadjustment,

use the Ashly security cover, which is available in both single and double rack space sizes. Installation is simple and does not

require removal of the equipment from your rack. See your Ashly dealer for details.
