ARCHITECT'S AND ENGINEER'S SPECIFICATIONS


The power limiter shall be a dual channel module that will limit an amplifier's power output to a predetermined level. The power limiter shall have an electronically balanced input, an unbalanced output, two male octal plugs, and be fully compatible with ALTEC LANSING's Anniversary Series of power amplifier products.
The power limiter shall have internal switch selectable power limits and response times tobe applicable in any sound reinforcement situation. It shall exhibit a feedforward design to eliminate any possibility of oscillation at high compression ratios, thus preserving a more natural sound.
The power limiter shall be the ALTEC LANSING Model 14712A.
