Stereo Pre-Amplifier with Home Theatre Bypass
The HA-1 doubles as a high fidelity stereo pre-amplifier with both RCA and XLR output ports. A special "Home Theatre Bypass" mode can be assigned to any input source, making it very easy to integrate the HA-1 as a stereo pre-amplifier into a home theatre sound system.
Discrete Class A Amplifier
Class A amplifier conducts signal over the entire range of the input signal cycle. The output transistors are biased to operate in their most linear range, and there is no crossover distortion caused by switching the signal between two push-pull devices
Asynchronous USB DAC
HA-1 turns any computer into a high performance multi-media source by converting digital audio to analog through the ESS Sabre32 Reference DAC.
Build Quality
The HA-1 is housed in a brushed aluminium chassis. The Class A amplifier naturally consumes more power and generate more heat than other types of amplifiers, so the HA-1 is designed with ample ventilation and built with the finest components to ensure long term stability and performance. Tipping the scale at 13 lbs, the HA-1 is a solidly built desktop headphone amplifier.
ESS Sabre32 Reference DAC
As the world’s best performing 32-bit audio DAC , ESS SABRE32 Reference DAC delivers an unprecedented DNR (Dynamic Range) of up to 135dB and THD+N (Total Harmonic Distortion plus Noise) of -120dB.
Toroidal Power Supply
A toroidal power transformer offers superior power efficiency and much lower exterior magnetic fields over traditional laminated steel core transformers. The HA-1's toroidal linear power supply provides a very clean and robust power source to the audio components.
Fully Balanced Design
The internal analog audio signal path of the HA-1 is fully balanced, providing better common-mode noise rejection and improves signal quality. The balanced headphone output provides twice the voltage and four times the power of the single-ended output, enabling the HA-1 to drive the most power hungry headphones.
Multiple portable devices for you choices
The HA-1 passes Apple's "MFi" certification and is compatible with the latest iPod, iPhone and iPad to be used as the digital audio output accessory of these devices.The HA-1 supports Bluetooth Advanced Audio Distribution Profile (A2DP) with both the standard and aptX® high quality codec. Simply pair your phone with the HA-1 and set music free wirelessly from your mobile phone.
