Altec Lansing 9440A

Description

The Altec Lansing model 9440A power amplifier is a direct coupled amplifier that typically delivers over 250 watts per channel into 8 ohm loads and over 450 watts per channel into 4 ohm loads at less than 0.25% total harmonic distortion.

An optional plug-in line bridging transformer may be used in each channel for balanced inputs.

The circuit design provides fail safe protection for the output transistors and the load.

Provision is made for mounting two accessory fans on the heat sink shroud for greater cooling of the output circuitry.

Designed for rack mounting, the 9440A occupies only four vertical units of rack space.

I run two of these amplifiers in my home system in bridge mode, they put out over 800 old school Watts each ,these amplifiers sound great with plenty of power to run any type of speaker

re: 9440A

This was the recommended mating amplifier to their (Altec Lansing) model nineteen (Voice of the Theater) speaker system. The speakers were "only" rated at 65 watts, but with 101db/1watt/1meter sensitivity and 250 watts of headroom, you really did feel like you were at a concert.
