Altec Lansing ADA880 manual Introduction, Specifications

Introduction

The ADA880 is a technologically advanced multimedia amplified speaker system featuring Dolby Digital AC3 and Dolby Pro-Logic surround

sound and stereo reproduction. The amplifier inputs can simultaneously operate on analog and digital (S/PDIF)* audio signals.

The unit is comprised of a subwoofer and two satellite speakers. This combination provides surround sound on a desktop by utilizing side firing speakers. For enhanced surround sound the top speaker portion of each satellite can be separated and placed on a provided stand with long speaker wires. This enables the separated speakers to be placed for best surround sound performance. Equalizer circuitry automatically resets to conform to the changes that take place when the speakers are separated.

The satellite speakers are magnetically shielded and can be placed close to a monitor without disturbing images. The speaker in the subwoofer is not magnetically shielded and should not be placed close to a monitor.

Subwoofer frequencies are non directional, therefore, the subwoofer does not have to be located in any particular relationship to the satellite speakers. Placing it on the floor close to a wall, corner of a room or under a desk gives excellent results.

The main satellite speaker has status indicators to show the various conditions of operation. A master volume control is used to separately adjust bass, center, surround and treble settings. Once the individual functions are set, the control reverts back to becoming a master volume control. A remote control unit is supplied that can access all the manual functions. The remote control has a mute function that is not available when using the controls manually.

The AC3/PRO-LOGIC/STEREO decode circuits operate automatically. If the unit is in the STEREO or PRO-LOGIC mode and an AC3 signal appears at the input of the amplifier, the circuitry automatically switches over to AC3. This and other automatic features are explained under “Using the Speaker System.”

If analog and digital signals appear at the input of the amplifier, the analog signal is automatically reduced in volume level.
