Hi! I use a T-Amp TA2400 for my 4hd15´s. But they are loaded with kappa LF´s, they are 600watt aswell. And 2 on each side was no problem. Ive had just 1 hd on each side at full power and had no problem with that either. The ta2400 is a better chooise then the ep2500 cus that one wont give you 600watt in 4 cabs at 4ohm. and that is what you will want =) |

Not true Thomann have delivered three T. Amps to me for 21 Euros, now that's the kneck end of 65 Kg! They've also shipped out two HK Audio 15" premiums series boxes (you can imagine the size and weight) with five mic stands and a T. Amp fro the same 21 Euros. Also Thomann use DHL |

Does anybody know in wich class the TA 2400 is. Is it in H-class or AB-class and does anyone have more specs. from the amp I searched already on the internet but i couldnt find anything.

The TA2400 is class H. The TAs aren't really good for bass, but anyday better than QSC PLX series (had an AB comparison, PLX lost). The ProLines are better for bass.

Funny, my STR3000 is H class and my PLX sounds equally as good despite being 400w less when running my subs

What actually determins which class an amp is? Also what are the definitions of the classes? |

amplifier classes Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more heat generated. Class A The amplifier conducts current throughout the entire cycle (360º). The Class A design is the most inefficient and is used in low-power applications as well as in very high-end stereo. Such devices may be as little as 15% efficient, with 85% of the energy wasted as heat. Class B The current flows only 180º for half the cycle, or two transistors can be used in a push-pull fashion, each one operating for 180º. More efficient than Class A, it is typically used in low-end products. Class AB Combines Class A and B and current flows for 180º to 200º. Class AB designs are the most widely used for audio applications. Class AB amplifiers are typically about 50% efficient. Class C Operating for less than half of one wave cycle (100º to 150º), Class C amplifiers are the most efficient, but not used for audio applications because of their excessive distortion. Class G A variation of the Class AB design that improves efficiency by switching to different fixed voltages as the signal approaches them. Class H An enhancement of the Class G amplifier in which the power supply voltage is modulated and always slightly higher than the input signal. Current Flowing The red indicates how much of the time current is flowing through one wave cycle. Class D Class D is a digital-like amplifier that works by turning a transistor fully on or off, but the "D" technically does not stand for digital. See Class D amplifier. Class T A variation of the Class D technique from Tripath. Class T modulates the pulses based on the individual characteristics of the output transistors. Stolen from here. Cheers, Angus |

Class H switches between FIXED voltage rails too. There is actually no big difference between G and H. There are differences in the output stage design, but the performance is similar. Class H is easier to design and has some other advantages, so it is preferred. The rail voltage modulating amps aren't put in a class. This is always a patented design and it is REALLY unusual. I'm aware of only two brands of amps with stepless rail regulation. The type of the power supply doesn't determine the class of the amp. There are Switch mode power supply (SMPS) amps of class AB (Peavey CS800S for example), class H (QSC PL, PL2, PLX, Dynacord LX, Camco Vortex, Camco Tecton and may many more), class D (PowerSoft DigAm, ASID Delta) and those 'unclassified' amps like LAB Gruppen fP and the Maintronic amps sold branded as FAT, PSE etc. |
