Altec Lansing ALA-435 (ca. 1989)
The Altec Lansing ALA-435 is a car audio amplifier from the late 1980s. Almost nothing is documented about it beyond a single group test in Audio (May 1989, p.46), where it was one of five amplifiers evaluated side by side with units from Blaupunkt, Canton, and Linear Power. No original price, production run, dimensions, or design details have turned up.
What survives are the bench measurements from that review. At rated power output, the ALA-435's frequency response was down 0.5 dB at 20 kHz (Audio, May 1989, p.46). THD+N measured 0.085% at mid-frequencies and 0.12% at 20 kHz. A peak showed up around 120 Hz, where distortion reached 1.8%. At 20 Hz and 40 watts per channel, THD+N was 0.85%. Dropping the output to 35 watts per channel brought low-frequency distortion down to just over 0.1% (Audio, May 1989, p.47). The damping factor was noted in the comparison alongside the other contenders (Audio, May 1989, p.48).
Beyond these figures, the ALA-435 appeared once in a magazine roundup and left no further trace in period directories, advertisements, or service literature.
