GENERAL PRODUCT DESCRIPTION

Altec Lansing’s 1662A mic/line mixer is a professional, studio quality solution for your permanent install mixing needs. The 1662A features six (6) microphone or line inputs with 20dB pad, TRS insert, and +48V phantom power. Each input channel has up to 60dB input gain, separate bass & treble controls, an output assign switch for sending signal to either or both outputs, and a level control. Stereo summing inputs on channels 5 & 6 provide a convenient way to add typical program sources from DVD, CD, or tape. The summing inputs can be connected for stereo-tomono or stereo-to-stereo operation. A full 11-segment LED array indicates levels on output A and B. Outputs are active servo-balanced.

Mic/line inputs and main outputs use Euroblock connectors, allowing bare wire to be easily connected to the mixer without soldering.

APPLICATIONS

The 1662A is useful for most sound reinforcement or public address needs. It is perfect for school gymnasiums, meeting rooms, Houses of Worship, lecture halls, and auditoriums. The 1662A can be set up as two mixers in projects where budget is tight. It can also be a stereo mixer for small, portable systems.

ARCHITECT’S AND ENGINEER’S SPECIFICATIONS

The unit shall be a six input mixer with two selectable outputs. Each input channel shall have a switch to select output A, A+B or B and a level control on the front panel. Each input channel shall have bass & treble controls located on the front panel. These controls shall consist of high and low shelving points fixed at 90Hz and 8kHz with 12dB of boost or cut. On the back panel each input channel shall have a 20dB pad, an in/out insert point on a ¼” TRS connector, and a Euroblock connector for balanced microphone and line inputs. +48VDC phantom power for each input must be available (back panel switch).

Each of the two outputs shall have a level control on the front panel and a Euroblock connector on the back. The outputs shall be active servo balanced.

The mixer unit shall be no higher than two rack spaces and must be fully covered with a five year warranty. The dimensions shall be 19 inches (48.3cm) wide by 3.5 inches (8.9cm) high by 6.6 inches (16.8cm) deep. The mixer shall weigh 10 pounds (4.5 kg). The mixer shall be the Altec Lansing Professional model 1662A.

As we are continually striving to improve Altec Lansing products, specifications are subject to change without notice.
