Technical Information
Recommended Amplifier
Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer long-term (or
RMS) power rating, dynamic range of the input-source material (crest factor), desired sound pressure levels,
and other factors. As a general guideline, the following table provides recommended power amplifier ranges.
Model
F1 Model 812 Passive
CAUTION: Failure to follow these guidelines may result in damage to the loudspeaker.
The Bose® PowerMatch configurable power amplifiers offer optimal amplification, amplifier limiting, digital
signal processing (DSP), and DSP presets for use with the F1 Model 812 Passive Flexible Array loudspeaker.
Please refer to the specifications listed on the pro.bose.com website for amplifiers and compare with the
table above to determine which model is best for your particular system design.
Recommended Signal Processing
Digital signal processing (DSP) is required for infrasonic bandpass protection, amplifier power limiting, and
active equalization to the F1 Model 812 Passive loudspeaker. Bose PowerMatch amplifiers provide all required
DSP functions, including amplifier limiting functions, as well as presets that automatically set all DSP values
for the loudspeaker in each of the four flexible array positions.
Bose ControlSpace® DSP hardware, including the ESP-880, ESP-1600, ESP-1240, ESP-4120, and ESP-00, can
also be used to provide active equalization and bandpass protection.
The latest Control Space Designer software for PowerMatch and DSP hardware, which contains the latest F1
preset files, can be found in the Software section of pro.Bose.com.
The following table lists the required infrasonic bandpass protection and amplifier limiter settings for the F1
Model 812 Passive loudspeaker when used without additional subwoofers.
