/></p> <h1>Hertz ADC (Advanced D-Class)</h1> <p>SP 4.900 is the first Hertz amplifier featuring the renewed <span>Hertz ADC (Advanced D-Class)</span> output stage, reaching up to 85% efficiency and delivering an impressive power rating of <span>160 x 4 (4_) W RMS</span> <span>or</span> <span>500 W x 2 (4_) W RMS</span> when bridged, with an ultra-compact size of 211.6 (8.3) x 130 (5.1) mm (in.). Being ultra-compact with an impressive power, SP 4.900 is the ideal choice for Motorcycle application and for under-seat in sport cars and behind-seat installations in trucks.</p> <p>Hertz ADC technology ensures SP 4.900 overtakes the usual <span>ultra-compact amplifier performances,</span> delivering an outstanding 105 dBA S/N Ratio and 0.02% THD specifications, and almost completely eliminating EMI and RFI noise, for<span> peerless sound quality.</span></p> <p>This versatility is perfect to drive high power (4_) front speakers with a bridged (4_) subwoofer.</p> <p>SP 4.900 is fully protected against overheating and DC outputs, immediately switching in protection mode (red led on) to save your speaker system.</p> <p><span>The IP55 certified Aluminum chassis</span> offers maximum protection against humidity and external agents and <span>the absence of internal cooling fan</span> prevents internal accumulation of dirt. SP 4.900 main board <span>has conformal coating layers</span> to prevent harm caused by internal condensation, a condition that can happen when warm, moist air meets the amp chassis of a lower temperature.</p> <p><span>SP 4.900 features a built-in sealed power cord, line inputs and speaker outputs</span> for a bulletproof motorcycle application providing safe power delivery in even the worse weather conditions. <span>The solid power supply harness </span>ensures ultra-stable power and ground connection, preventing any loss of contact caused by vibration. Due to his specialized design, <span>SP 4.900 is the ultimate option for Motorcycle, Marine, and Powersports applications.</span></p> <p>SP 4.900 features <span>built-in USS (Universal Speakers Simulator)</span>, a dynamic load circuit on Hi-Level inputs which initially shows the OEM output channel a load low enough to neutralize OEM speaker outputs muting protection circuit. Once the circuit activates, a higher load is introduced _ still low enough to damp Class D outputs, but not low enough to cause current issues or heat dissipation problems.</p> <p>SP 4.900 offers both remote-in signal detection and DC offset sensing on the speaker inputs for automatic turn on, providing total integration with any vehicle.</p> <p><span>The versatile crossover filters and control knob are all located on a single side</span>, to allow an easy calibration when the product is installed.</p> <p>The filters section includes extremely flexible high-pass and low-pass crossovers, adjustable from 50 Hz to 5 kHz with 12 dB/Oct 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 related speakers.</p> <p>The high-pass crossover can also be used to optimize the performance of SPL Show NEO high-efficiency coaxial speakers, the perfect partners for SP 4.900.</p> <p> </p> <h2>General Specs</h2> <table border=
