Timpano Compact 4 Channel TPT500.4 Car Audio Amplifier – 4x 125 Watts at 2 Ohm – Mini Stereo 12 volts Fullrange Class D Amp Bridgeable Small Footprint Technology! HD Sound Quality! Timpano amplifiers raises power amplification to a new standard of quality and usability. The new line delivers the most innovative and powerful Brazilian technology in compact full range amplifiers on the market. Loaded with features, it provides an unsurpassed efficiency rate of 80-90% in a compact Class D full range amplifier. COMPACT DESIGN: Digital class D Brazilian technology allows this amplifier to have a small footprint by integrating a high-speed mosfet power supply with top of line transistors to ensure performance in a small heat sink without compromising performance. Dimensions: 3.93″ depth x 5.02″ width x 2″ height POWER: This amplifier is designed to run your stereo system with the power it needs to perform! 500 Watts maximum dynamic RMS power output of 4x 125 Watts at 2 Ohm per channel. Its high efficiency rate of 87% provides more power with less battery consumption. BRIDGEABLE: Double the power output to your speakers by bridging two channels. Minimum impedance of 4 Ohm per bridged channel at output power of 2 x 225 Watts RMS TECHNOLOGY: A smart electronic 2-way protection circuit protects the amp if it gets too hot or if speakers fail causing a short! Focusing in sound quality, a full range response of 10 to 24,000Hz was used to give the best sound reproduction on this tiny amplifier. FEATURES: Heavy Duty 10 Gauge power and speaker wire Inputs. Built-in crossover filters for easy tuning! Choose between a fixed HPF at 90Hz or LPF at 90Hz + 45Hz Bass Boost or just turn it FLAT and use your external crossover or DSP settings. It also includes Variable Gain Control. Level controls are not for adjusting volume. They adjust the amount of signal that is coming into the amplifier from your signal source.
