Yamaha F-1030 (Late 1970s)

Name: Yamaha F-1030
Brand: Yamaha

Little documentation has survived for the Yamaha F-1030 beyond its appearances in the late-1970s professional audio press. Those sources show a serious piece of studio and PA gear: a professional electronic crossover, or what Yamaha called a frequency-dividing network, built for bi-amplified and tri-amplified systems.

Modern Recording (June 1977, p.26) reported on the F-1030 at a Yamaha product showing. It called the unit a professional electronic crossover, switchable for two-way or three-way operation, offered for portable concert reinforcement systems, studio monitor systems, and discotheques. Crossover frequencies were selectable at 250 Hz, 500 Hz, 800 Hz, 1 kHz, 1.2 kHz, 1.5 kHz, 2 kHz, 2.5 kHz, 5 kHz, 6 kHz, 7 kHz and 8 kHz. The slope rates could be switched, but the period report doesn't give slope values.

Yamaha's own advertising in Modern Recording (November 1979, p.68) and Recording Engineer (October 1979, p.101) pitched the F-1030 as a way to "divide and conquer" distortion and clipping, replacing individual passive crossovers with an active network. The same ads pointed out dB-calibrated detented controls on both inputs and outputs, which was unusual among competing dividing networks. They also listed a 12.3-volt output into a 600-ohm load and the ability to accept input levels up to +30 dB. The F-1030 was described as part of Yamaha's Professional Series.

Beyond those period appearances, the record is thin. No production years, original price, or service documentation has surfaced in the Archive's files.
