Key recommendations

You can find below some key recommendations to get the most out of your amplifier:

  1. Read this instruction manual carefully before carrying out any connection; Any connection to the amplifier input or output must be carried out when the amplifier is off;
  2. Check carefully the polarity of power supply wiring (battery’s positive and negative terminals) loudspeakers and the minimum speaker impedance;
  3. It is compulsory to install circuit breakers to protect against overloading. The circuit breaker must be installed as close as possible to the battery and sized up according to the amplifier;
  4. The gauge of power supply wiring is extremely important both to reach the desired amplifier output and to the amplifier’s safety. Use the wire gauge recommended in this manual (page 11). Using wire gauges below the specified value will result in power loss and overheating of cables. The power supply cables must be the shortest possible;
  5. The amplifier must be installed in a firm and ventilated area;
  6. To avoid interferences, the signal cable (RCA) must be away from the original wiring of the vehicle or any other power supply cable;
  7. The amplifier must be installed by a qualified professional.

Taramps reserves the right to modify the contents of this document at any time without prior notice and does not have the obligation to apply the changes in units that were previously produced.

Functions & inputs

  1. LED ON: Indicates that the amplifier is on.
  2. CROSSOVER: Set the operating mode of the amplifier:
    • SELECTOR POSITION – FULL
    • Amplifies the whole audio range, responding from 8Hz to 35KHz. This function is normally used when there is an external crossover in the system.
    • SELECTOR POSITION – HPF – (HIGH PASS)
    • Amplifies signals with more intensity from the selected frequency ranging from 80Hz to 2.2KHz  (-6dB / Octave). This type of function is used for playback of mid-bass, mid-range speakers, horns or tweeters.
    • SELECTOR POSITION – LPF – (LOW PASS)
    • Amplifies only bass signal, the response is limited to 80Hz (-12dB/8ª), an optimal frequency cutoff for sub-woofers.
  3. HIGH PASS(HPF): Variable adjustment from 80Hz to 2.2KHz, which determines the beginning of the amplifier operating frequency, when selecting HPF mode.
  4. GAIN: Adjusts the input sensitivity of the amplifier, allowing a perfect adjustment to the output signal levels of various head unit models on the market. It is possible to adjust from 6V (minimum sensitivity) to 0.2V (maximum sensitivity).
  5. INPUT: Inputs of signals to be amplified. Connect these signals to the RCA outputs of the Head Unit, using good-quality shielded cables to avoid noise interference.

Power supply connector

  1. POWER (Power Supply Connector): The connector terminal (+) must be connected to the battery’s positive pole with a 4mm² (minimum) wire gauge. The connector terminal (-) must be properly connected to the battery’s negative pole with the same wire gauge. The remote terminal must be connected to the Head Unit REMOTE output with a 0.75mm² wire.
  2. OUTPUT: To connect the speakers. Follow the polarity and the minimum impedance recommended.
    • For STEREO connections, the minimum impedance is 2 ohms at each channel; for BRIGDED connections is 4 ohms.
    • To combine speakers, the resulting impedance must be taken into consideration.
    • See the examples below:
  • *  **Protection system**
    • Short-circuit Protection: Shut down the amplifier when detecting a short- circuit or impedance lower than the supported at the output.

Installation

CAUTION: All connections to the power supply, input, and output connectors must be carried out only with the amplifier off.

Recommended wire gauge & fuse

  • Positive/negative power supply cable _____ 11 AWG
  • Output cables with gauge_ _____ 15 AWG
  • Remote cable _____18 AWG
  • Protection fuse or circuit breaker _____20A
  • Caution: Using wire gauges below the recommendation will result in power loss and overheating of wiring.
  • Check polarity and never reverse power supply cables due to the risk of damage to the amplifier.
  • Calculated considering a maximum length of 4m. Distance greater than this, you will need to increase the cable gauges.
  • It is compulsory to install protection fuses or circuit breakers as close as possible to batteries.
  • Connection example in the output: Stereo
  • Note: In the case of horns and tweeters you must install a passive filter in the positive terminal of the same ones (Consult the transducer’s manufacturer manual).

Technical features


  • Rated power with 60Hz to 1KHz sinusoidal signal and THD <= 1%, with resistive loads, measured with Audio Precision APx525 audio analyzer or equivalent and the product at lower than 50°C case temperature and 12.6V supply voltage.
  • Frequency response measured at 2 times the minimum impedance, in 2 channels mode.
  • The values as above are typical and may vary, due to electronic components tolerance or manufacturing process.
