The TDA7498E is a dual BTL class-D audio amplifier with a single power supply designed for home systems and active speaker applications.
This amp is TDA7498E chip version not normal TDA7498 or TDA7498L chip,TDA7498E version support Max. 160W*2 output.Upgrade IC chip to TDA7498E 160w + 160w R.M.S. + TL082 OPAMP
Suitable for 2Ω-8Ω Speakers and Subwoofer !
Reasonable price than alternative TDA7498(100W ) amp
Black color optional(please note if you want this color.)
1.Double DC speaker protection function:
can protect your speaker under extreme condition(for example: when the output is up to DC20V or above)
2.Wide power supply:
With a polarity reverse connection protection circuit,can be functioned well under 24V- 38V voltage,so you can connect external power supply without worry for self DIY!
For example,36V power supply,can drive 4Ω low impedance high power speaker without Speaker staccato.
3. Use digital amplifier Special inductive,very perfect LC circuit,can drive up to 200W sound box without damage the amplifier,matching with the 36V4.16A power supply we offer can be used with most popular speakers.
4.Processing function: the newest analog class D audio power amp TDA7498E
The High current output characteristics of TDA7498E not only ensured high power output but also solved the problem of power or current limit for 8Ω-2Ω Impedance speakers.
TDA7498E also intergrates Built in noise suppression,Standby function,Mute function,etc. to improve sound quality function in terminal application, and quite suitable to inhibit Balanced input of TDMA Noise.
5.Built-in Intelligent current protection function, can identify the peak current frequency range of speaker requires,and autiomatically preventing audio stream output interrupt.
6.TDA7498E can achieve the flexible configuration of audio system between stereo and mono mode ,provide Mono parallel function, can drive subwoofer speaker/Bass speakers of 2.1 Audio system configuration.
TDA7498E Amplifier Characteristics：
1. Pre-amp adopts Musical Fidelity A1 pre-amp original circuit design
2.First adopts TDA7498E super chipset, real 2*160W stereo circuit design,BTL otput, digital amplifier Special inductive 20A,high power,Ultra low resistance,no electromagnetic interference between adjacent inductance,Magnetic saturation does not occur.
3.PCB adopts FR4 top-level KB material,2OZ copper thickness, can ensure fluent large current,low internal resistanceof Signal, high fidelity.PCB adopts Immersion gold process,Signal transmission is much better than ordinary PCB.
4.The power amp Parallel 2 Philips BC large electrolytic capacitors,can meet the need of large power loaded，Capacity is up to 6600UF.
5.Built-in Standby and mute circuit, no pulse sound when switch on/Off,can well protect your beloved speakers.Additional external Smart protection speaker protection circuit can protect your speakers from damage even at extreme DC output situation.
6.Matching super large heatsink to the main amplifier board,to ensure TDA7498E can work steadily without thermal overload
7.Aluminum drawing Oxidation coloring CNC processing chasis,good touch feeling.
8.High quality components in use:NICHICON MESEcapacitors,WIMA capacitors,DALEResistors，RIFAcapacitors，EVOX SIEMENS capacitors,digital amplifier Color ring Special inductance etc....
