FR-1000
class-D / RACK-MOUNT stereo amplifier

FR-1000is rack-mount type stereo power amplifier; User is capable to choose from the rich features for the desired application, and does fine tuning to the audio for optimum sound performance.

The FR-1000 has most of its functions and

features, managed and controlled by CPU. Flexibility, power and control are what it is designed for.
The high efficiency switching mode power supply, generating power to drive speakers through the digital / class-D amplifier, allows low-profile of 1U and low weight for this model.

 

Incorporating the advanced DSP technology, the FR-1000 has CPU built in to provide capability of adjusting and storing the amplifier’s functions and working parameters through notebook computer (via the USB aperture), on-panel encoder or with the supplied remote control handset during the installation and acoustic refinement.

(see table below for DSP functions)

keep all the settings in the built-in CPU (3 sets)

On the front panel a rotary encoder (with OK button on center) is available for function selection and parameter setting, in addition to the included remote handset. To assist the setup, particularly when using the remote handset, a dot-matrix LCM panel is provided to give feedback of the unit’s status during browsing functions, doing controls and making selections.

 

The FR-1000 is equipped with RCA jacks (the most commonly-used connector) and XLR terminals (for higher immunity and less noise).

XLR connector is rigid and provides much higher standard of S/N ratio when a long signal cable between source and the subwoofer speaker is needed (for instance, outdoor or in a ballroom), compared to the other types of signal connectivity.
