INTRODUCTION
Here are the “no-compromise” power amplifiers ! The new Symbol Power Amplifier series features two models based on a project design
targeted to obtain the most appropriate technical solutions to each and every need of signal amplification. The Symbol 12000 and the
Symbol 16000 grant stereo power output of respectively 1500 W and 2400 W per channel (into 2 ohm).
All the steps followed for this project have been directed to the achievement of the maximum performance at every stage of application:
nothing has been saved from this “mission”! The application of Cascode circuits, of over-dimensioned final stages, of highly efficient
techniques such as the use of power supply at 2 or 3 steps and the highest capacity of electricity distribution.... The great quality of these
amplifiers guaranteed by the traditional FBT reliability and the rich equipment of technical features, place the Symbol 12000 and Symbol
18000 to the top of the range and confirm FBT’s target to offer the right audio solution to every need.
TECHNICAL CHARACTERISTICS:
> XLR connectors for signal inputs and outputs
> electronically balanced inputs
> power outputs with 4-pole Speakon connectors
> facility for operation in parallel, mono or stereo modes
> power line thermal cut-out protection
> independent protections on each channel
> soft start function
> delayed activation of outputs
> dual loudspeaker protection to safeguard against continuous
voltage on output (relay)
> short-circuit protection on outputs
> SOA protection
> clip limiter
> 8 dual-colour LED’s providing comprehensive at-a-glance
display of operating modes
> ground lift switch
