Top amplifier Audison TH quattro
The Audison TH amplifiers were born from the experience gained with the HV venti amplifier enhanced by the innovations of digital technology. The result is a perfect combination of the highest level of analog technology and advanced digital technology functions in one unique product. A rare synergy with Full DA HD technology takes the in-car listening experience to a new level of excellence. The TH quattro is a four-channel amplifier fully adjustable and fully controllable by an internal microprocessor for unlimited system configurations.The main features of the Audison TH quattro amplifier
- Class A amplifier, integrated 24-bit / 192 kHz Hi-End DA converters.

| Number of amplifier channelsAmplifiers are divided into: - Monoblocks - 2-channel - 3-channel - 4-channel - 5-channel - 6-channel - multi-channel Each channel is used to power one speaker for the coaxial type, or one side if they are component speakers. Monoblock type amplifiers are mainly used for subwoofers. 2-channel are suitable for both subwoofers and, for example, the front pair of speakers in a car. 3-channel is used for front or rear speakers + subwoofer. 4-channel are used for front + rear speakers or 1 pair of speakers + subwoofer. 6 or 5-channel are used for 2 pairs of speakers + subwoofer, most often. Bridging means connecting the amplifier to a bridge, using the + pole from one channel and the - pole from the other channel. In most cases this is shown as "BRIDGED" on the amplifier. | 4 |
| Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers. | AND |
| RMS power into 4 ΩRMS power when loading speakers or subwoofer at 4 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier. | 4 x 160 / 2 x 500 / 2 x 150 + 1 x 540 W |
| RMS power into 2 ΩRMS power when loading speakers or subwoofer at 2 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier. | 4 x 260 / 2 x 700 / 2 x 250 + 1 x 650 W |
| RMS power into 1 ΩRMS power when the subwoofer is loaded at 1 Ω. RMS power is the constant power of the amplifier and is one of the most important parameters when choosing an amplifier. When connected to 1 Ω, significant heating of the amplifier may occur. | 4 x 340W |
| Harmonic Distortion (THD)Total harmonic distortion indicates how much the input signal is distorted in the amplifier. Distortions appear as overtones contained in the output signal. The proportion of originally absent parts of the signal is given as a percentage, typical values are between 0.001% and 0.5%. Distortion is measured in their power band. If it exceeds the limit of 0.7% from a certain power, it is the value of the output power of the given amplifier, from which it no longer plays without distortion and from which the distortion usually increases steeply, so that no further increase in power can be counted on. The lower the value, the better. | 0.03% |
| Signal-to-noise ratioThe signal-to-noise ratio means that the output signal always contains noise. The signal-to-noise ratio expresses how much of this noise is compared to the useful signal. The so-called A value is given, which does not take deep and very high frequencies into account. This corresponds to the characteristic of human hearing, which is not so sensitive to deep frequencies, especially below 1 kHz. The higher the value, the better the amplifier is. | 104 dB |
| Input sensitivityIn order for the amplifier to perform its function correctly, it requires an input signal of a certain level, which is different for car radios. It is measured in "Volts" (e.g. 2 V, 4 V, etc.) The higher the value at the output of the pre-amplifier, or car radio, the less demands are placed on the power of the amplifier. However, the amplifier must allow this input sensitivity, and for that reason this value is also given for the amplifier. | 0.3 - 4.8 V |
| Damping factorDF - Damping Factor . It is the ratio of the load (repro + cables, crossover, etc.) to the internal resistance of the amplifier. The bigger the DF, the more controlled the bass. Amplifiers with a lower DF tend to hum. Subwoofers with a higher Q in the bass reflex and sometimes in the enclosure will also cause humming. | 80 |
| Socket input terminalsFerrule terminals allow better wiring contact to the amplifier. It is also a more secure form of terminals. If you are tightening the sleeve terminals, we recommend retightening them after 1 day, as the connected cable gradually compresses. | Yes |
| The value of the fuses on the amplifierFrom the value of the fuses on the amplifier, you can get a true picture of the real performance of the amplifier. | 100 A |
