Introducing A Fully Balanced Headphone Amplifier - The A70 Pro
A fully balanced headphone amplifier that elevates your listening experience is the Topping A70 Pro. This powerhouse offers unmatched audio performance thanks to its cutting-edge T'ang-ku-la Module, ultra-low noise input stage, and massive 17000mW x 2 output power. And with the added benefit of serving as a preamplifier, the A70 Pro adapts to your audio needs. With precise control, programmable settings, and a vibrant Aurora UI all-in-one stylish package, dive into the world of high-fidelity sound!
Features T'ang-ku-la Module With 3-Stage Feedback Circuit
The three-stage feedback circuit used by the T'ang-ku-la Module is new. The dynamic range increased to a record-breaking new level of 147dB by reducing noise and high-frequency distortion. Due to the technology's significant reduction in heat generation, reliability, the lifespan of electronic components, and thermal noise are all significantly improved. The A70 Pro's newly developed ultra-low noise input stage further enhanced the noise performance of balanced input and increased the input impedance to 20kΩ, improving compatibility with incoming devices. It also has a newly optimised new circuit architecture.
Redesigned Gain Architecture And Ground Loop Noise Switch
The gain architecture has been redesigned to reduce noise and distortion at high gain stages than the previous architecture. The A70 Pro has two level gain settings allowing you to pair high-sensitivity IEMs and high-impedance headphones. Ground loop noise may be experienced when using multiple devices simultaneously. A GND/LIFT switch is added to the A70 Pro. Change to LIFT to eliminate ground loop noise.
Relay Volume Control With Independent Volume Memory
The Topping A70 Pro uses relays and resistor networks to form an R2R volume control module, which provides precise volume control, long service life, and will not deviate even at low volume. The A70 Pro can memorise eight sets of volumes separately and automatically revert to the last used volume the next time the output is selected. The eight groups are headphone amp + preamp output, earphone all output, preamp all output, only 6.35mm output, only 4.4mm output, XLR output, RCA output and XLR output. Press and hold the C1/C2 button on the remote control for 3 seconds to save the current status (Including input channels, output channels, volume levels, and all settings in the setup menu). After successfully saving, press C1/C2 to use the corresponding settings.
Doubles-Up As A Preamp With A 12V Trigger Interface & A Remote
The A70 Pro functions well as a preamp and a driver for headphones. With an RCA output impedance of only 50 and an XLR output impedance of only 100, it offers the same high performance as the headphone amp mode. Additionally, a variety of power amplifiers with a variety of input impedances can use it. A fully functional remote control also makes operation even simpler. The A70 Pro has a 12V Trigger input and output interface, which allows for passive and active activation of other devices, triggering them to turn on and off simultaneously.
Elegant New-Generation Aurora UI With Expandable Inputs
Three touch buttons and a full-colour screen on the A70 Pro let you adjust the playback information, FFT, and VU to your tastes. You can access more features by turning the volume knob. One set of balanced XLR and single-ended RCA inputs are available on the A70 Pro. However, the Ext90 input expansion gives you a total of two single-ended RCA inputs and four balanced XLR inputs.
A Perfect Match With Topping's D70 Pro Sabre DAC
The Topping A70 Pro and D70 Pro SABRE have identical design languages and can meet the needs of the vast majority of headphones and active speakers. The A70 Pro and D70 Pro SABRE can be switched on and off in conjunction via the 12V Trigger connector, allowing the A70 Pro to be synchronised with the D70 Pro SABRE for automatic or manual switching.
