The ZRS Smart Tech amplifiers feature a full LCD display that monitors and indicates all working functions of the amplifier in real time with a proprietary programmed computer chip.
When the ZRS Smart Tech amplifier is first turned on, the diagnostic system scans the amplifier circuitry and internal operations for start up status, the LCD will display the amplifier model number and the system status - SYSTEM OK.
It then proceeds to monitor the performance of the amplifier and will display DC voltage and amplifier internal temperature. Should there be a problem at some time the ZRS Smart Tech can actually diagnose something as a faulty output transistor and shut down the amplifier before any DC voltage reaches the speakers. If the amplifier begins to “square wave” the display will indicate distortion and the channel where the problem is, if the amplifier thermals it will clearly indicate “Thermal Protection Mode” if an output transistor blows, it will indicate “DC Protection Mode” and so on...
What's a nice feature on these amplifiers is the “Peak Limiting Compression Circuitry” that is built in to the Class D mono block amplifiers. By turning on the Peak Limiter switch, the amplifier will never go in to distortion, the amplifier will automatically analyze the input signal and gain of the amplifier and reduce the wave to avoid clipping and distortion. But what’s very nice about this circuit is that if the customer ever does want to compete, he can turn the Peak Limiter off and clip the amp into distortion thereby raising the SPL of the system.
The ZRS Smart tech amplifiers also features our own unique BASS FOCUS circuitry. As installers many times are forced to install woofers in enclosures that are too small for optimal bass response. The Bass Focus will actually fool the woofer into thinking it has more air behind it than it actually does and will play down to a lower octave. This function is also very useful for door speakers to add that extra punch without stressing the speaker into distortion and thermal damage.
Of course all the mono block amplifiers in the ZRS Smart Tech line can be bridged and daisy chained via our Master/Slave circuit and all controls thereby are handled by the master amp guaranteeing perfect system gain and crossover matching.
The ZRS Smart tech 4-channel amplifier has a CLONE FEATURE so that when the amp is bridged, all gain and crossover functions are controlled by channels 3 and 4 which guarantees perfect tracking between all channels.
The 2 channel ZRS D250.2 and D350.2 are full range digital amplifiers and provide clean, full range power, with lower distortion and a fuller, richer, warmer sound than any other full range class D amps on the market. The design helps keep things cool even at extreme high power levels.
