{"product_id":"4-channel-class-a-b-amplifier","title":"4-Channel Class A\/B Amplifier","description":"The PowerBass ACS 4120 is a 4-channel, high-efficiency Class A\/B amplifier engineered for delivering powerful and clean audio in a compact chassis. It utilizes selected SMD components and a robust 6 oz\/kg high-density heat sink to ensure maximum efficiency and effective cooling, even in tight vehicle spaces.\n\nThis amplifier boasts impressive specifications, including 480 watts of total RMS power (60W x 4 @ 4 ohms or 120W x 4 @ 2 ohms) and a peak power output of 960 watts. It features a PWM MOSFET power supply and is 2-ohm stable, with the capability to run in 4-ohm bridged mode for even more power. The ACS 4120 provides flexible audio routing with its variable high-pass (50 Hz - 1 kHz) and low-pass (30 Hz - 250 Hz) electronic crossovers, each with a 12 dB crossover slope. It also includes a selectable 12dB bass boost EQ and a variable gain control for fine-tuning your system.\n\nConnectivity is made easy with both high-level (speaker) and low-level (RCA) inputs. The amplifier is equipped with a remote soft delay turn-on\/off circuit to prevent turn-on thumps. For peace of mind, it incorporates a multi-stage protection circuit that guards against impedance overload, speaker short circuits, thermal overheating, and DC output issues.\n\nWith its low distortion and high-fidelity audio output, the ACS 4120 is an excellent choice for those seeking a balance of performance and value in a compact amplifier that fits well in nearly any vehicle.","brand":"PowerBass","offers":[{"title":"Default Title","offer_id":52872170635576,"sku":"ACS 4120","price":299.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-channel-class-a-b-amplifier","provider":"MOTORMIA","version":"1.0","type":"link"}
