The SP 4.900 is the first Hertz amplifier to feature the new Hertz ADC (Advanced D-Class) output stage, achieving up to 85% efficiency and delivering an impressive rated power of 160 x 4 (4 \u03a9) W RMS or 500 W x 2 (4 \u03a9) W RMS when bridged, in an ultra-compact 211.6 x 130 mm footprint. The SP4.900 is the ideal choice for motorcycle applications thanks to its size and enormous power output.<\/p>\n
Hertz ADC technology ensures that the SP 4.900 outperforms ordinary ultra-compact amplifiers, delivering an exceptional S\/N ratio of 105 dBA and 0.02% THD, and almost completely eliminating EMI and RFI interference for unparalleled sound quality.<\/p>\n
This versatility is perfect to drive high power (4\u03a9) front speakers with a bridged (4\u03a9) subwoofer.<\/p>\n
The SP 4.900 is fully protected against overheating and DC outputs, instantly switching to protection mode (red LED lit) to save your speaker system.<\/p>\n
The IP55-rated aluminum housing provides maximum protection against moisture and external factors, while the absence of an internal cooling fan prevents dirt buildup. The SP 4.900 motherboard is coated with a conformal coating to prevent damage from internal condensation, which can occur when warm, humid air comes into contact with the amplifier's lower-temperature chassis.<\/p>\n
All controls are protected by a removable aluminum panel to make the SP 4.900 IP55 compliant, preventing moisture from entering the switches.<\/p>\n
The SP 4.900 features a built-in sealed power cable, line inputs, and speaker outputs, ensuring safe power even in the harshest weather conditions. A robust power harness provides an ultra-stable power and ground connection, preventing vibration-induced loss of contact. Due to its specialized design, the SP 4.900 is the best option for motorcycle applications.<\/p>\n
The SP 4.900 features a built-in USS (Universal Speaker Simulator), a dynamic load circuit on the Hi-Level inputs that initially presents the OEM output channel with a load low enough to neutralize the OEM speaker output muting protection circuit. Once the circuit is activated, a higher load is introduced\u2014still low enough to attenuate the Class D outputs, but not low enough to cause current or heat dissipation issues.<\/p>\n
The SP 4.900 offers both remote input signal detection and DC offset detection on the speaker inputs for automatic turn-on, ensuring complete integration with any vehicle.<\/p>\n
The universal crossover filters and control knob are located on one side to allow for easy calibration once the product is installed.<\/p>\n
The filter section features extremely flexible high-pass and low-pass crossovers, adjustable from 50 Hz to 5 kHz with a 12 dB\/octave slope. Together with a bass boost control (45 Hz, 0-8 dB), they allow both front channels to be configured for full-range operation or for use with a subwoofer and associated speakers.<\/p>\n
The high-pass crossover can also be used to optimize the performance of the high-performance SPL Show sx165neo, sx690neo, and sv165neo coaxial loudspeakers.<\/p>","protected":false},"excerpt":{"rendered":"
