Description The Taramps BASS 400 digital amplifier module was carefully developed with the latest technology, with high output and performance for automotive sound systems focused on subbass and bass responses, in the frequency range from 8hz to 250hz. It has a maximum power of 400 watts in 1 2 ohm channel, with personalized adjustments according to the size of the trunk and the most prominent frequency of each vehicle, through bass boost and the option to choose the central frequency. This amplifier module can offer much more excessive displacement control, through the subsonic filter, volume control and low pass, to get your bass just right. Technical specifications: Operation class: class d. is the indication of the construction of an amplifier, class d (also called digital) due to the pwm (pulse width modulation) used in its operation, it allows for a small, efficient amplifier with reduced heating compared to other construction classes . Number of channels: 01. Number of channels to use in your project, with this specific model you have the option of connecting only 1 channel. Power @14.4v 2 ohms: 400w rms. The power with a voltage of 14.4 volts is related to the operation of the vehicle/power source. Power @14.4v 4 ohms: 214w rms. The power with a voltage of 14.4 volts is related to the operation of the vehicle/power source. Minimum input sensitivity (100% level): 320mv (rca) - 6v (wire). Lower voltage required for maximum results with the amplifier, that is, with low volume on the radio, we will achieve good results. Frequency response: 8hz ~ 250hz(-3db). With the frequency response it is possible to identify the application of the amplifier, so if the speaker or any other type of transducer you are using is understood within this response, it means that we can use that product in your project. Variable crossover low pass (lpf): 55hz ~ 250hz. Lpf or low pass filter (term in English) means low pass filter, that is, it allows everything that is below this reference to be reproduced and what is above this indication will not be used, a common use of this function is to reduce the presence of voice on subwoofers. Variable high pass crossover (hpf): 8hz ~ 30hz (-12db/8th). hpf or high pass filter (term in English), meaning high pass filter, that is, it allows everything above this reference to be reproduced, the common use of this function is to reduce the presence of bass in door speakers, for example . Bass boost: parametric, frequency: 35hz ~ 60hz boost: 0 ~ 12db. Bass boost is the bass reinforcement for the amplifier's sub channel, that is, an "extra" reinforcement for the bass. Supply voltage: 9 to 17v. It is the operating indication of the amplifier where it will have the minimum and maximum voltage for its operation, outside of this specification it will not turn on or activate protection. Consumption at rest: 0.5a. This is the reference for the consumption of the amplifier turned on and without music. Maximum musical consumption: @14.4vdc: 17.5a. This is the estimated consumption of the amplifier working at the minimum impedance playing music at maximum volume. Maximum consumption in sinusoidal signal: 35a. Reference for bench/laboratory tests under specific conditions with resistive load, fixed frequency and stable power supply. Protection system: output short, output short in relation to gnd, low voltage protection Impedance, high/low voltage protection and thermal protection. This system exists to protect the operation of the amplifier. It can be related to the output, when we have connections below the minimum impedance, a short circuit in the installation or even speakers with problems. This protection may also occur due to voltages outside the operating range, or even thermal protection that occurs due to conditions in which the amplifier heats up above normal. Dimensions: width 13.4cm x height 4cm x depth 13.8cm. Weight: 0.57kg Package contents: 1 BASS 400 amplifier module; 1 connector for wired audio input (input) approximately 20 cm long; QR code to download the manual; 1 Taramps Sticker. Important: We recommend that installation be carried out by a specialized professional and we are not responsible for misuse of the product.
