    OPPO Pachet Amplificator de Casti HA-2SE + Casti PM-3


    Amplificator de Casti OPPO HA-2SEHigh-Resolution Audio Meets Style and DesignHA-2SE is an elegant yet sophisticated portable headphone amplifier with built-in rechargeable battery. It is engineered to enhance music playback from mobile phones and portable music players.Its genuine leather casing with contrast stitching and bevelled aluminium edges are eye-catching. And it is conveniently used to charge mobile devices on-the-go and itself can be efficiently charged in 30 minutes.Polished-sounding, gutsy performerHigh-resolution USB DAC for Apple/Android/PC/MacESS Sabre32 Reference ES9028-Q2M DAC chipFeaturing hybrid class AB amplification and a USB DAC that supports 384 kHz PCM and DSD256, the HA-2SE offers high performance digital-to-analogue conversion for Apples iPhone/iPod products, a wide range of Android devices, PC and Mac computers.For music on the moveHeadphones, from very sensitive In-Ear Monitors to the most power-hungry Over-the-Ears, can all benefit from the HA-2SEs excellent performance and powerful amplification.Hybrid Class AB AmplifierThe HA-2SE's power amplification circuit for the headphones is Class AB built with integrated circuits (ICs) and discrete transistors. The output transistors are biased to operate in their most linear range for the critical small signal, and deliver their full potential when power is required.ESS Sabre32 Reference DACWith the ESS patented 32-bit Hyperstream DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented performance for mobile applications.Asynchronous USB DACHA-2SE turns a smartphone into a high performance digita laudio player. The asynchronous USB DAC input also works with PC and Mac computers to replace the built-in sound card and support high-resolution audio playback with PCM up to 384 kHz 32-bit and DSD up to 12 MHz (DSD256).Clean Signal PathThe HA-2SE provides a clean signal path for the audio by avoiding re-digitizing the audio signal for volume adjustment or bass boost.Rapid ChargingThe HA-2SE features patented VOOC rapid charging technology from OPPO. Using the supplied rapid charger the internal battery can be quickly and safely charged to 70% capacity in about 30 minutes.Build QualityThe HA-2SE is housed in an aluminium chassis wrapped in genuine leather. The bevelled metal edges and contrast stitching on the leather are eye-catching. The HA-2SE meshes equally well in the pocket of an urban Millennial or on the desk of a business executive.Made for iPad, iPhone, iPod and Compatible with AndroidThe HA-2SE is both compatible with the latest iPod, iPhone, iPad and android devices that support USB OTG (USB On-The-Go) and USB Audio Class. Music from your favourite portable device will sound its best.Mobile Power BankThe HA-2SE functions as an external battery pack to charge your mobile device. You can ditch the bulky spare battery pack and carry just the HA-2SE with you mobile phone.Audio-in and Line-outThe HA-2SE has a 3.5 mm Audio-in port to support portable music players that do not have a USB-compatible digital output. While the HA-2SE is used with one of its USB digital input ports, the 3.5 mm jack acts as Line-Out for the USB DAC.Two Gain SettingsThe HA-2SE offers two gain level settings for optimal headphone matching, the High Gain mode for driving large power-hungry headphones and the Low Gain mode for sensitive In-Ear Monitor type earphones.Bass BoostThe HA-2SE offers a Bass Boost function for those who like a bit more punch and impact with their music.Hybrid Class AB AmplifierThe HA-2SE's power amplification circuit for the headphones is Class AB built with integrated circuits (ICs) and discrete transistors. The discrete transistor output stage uses hand-picked and matched parts. The output transistors are biased to operate in their most linear range for the critical small signal, and deliver their full potential when power is required.Clean Signal PathThere is no DSP (Digital Signal Processor) in the HA-2SE. Volume control is operated by a combination of the DAC chip's internal digital volume control and an analog potentiometer (the familiar volume knob). Bass boost is performed by pure analog audio circuits. By avoiding re-digitizing the audio signal for volume adjustment or bass boost, the HA-2SE provides a clean signal path for the audio.Audio-In and Line-OutThe HA-2SE has a 3.5 mm Audio-In port to support portable music players that do not have a USB-compatible digital output. While the HA-2SE is used with one of its USB digital input ports, the 3.5 mm jack acts as Line-Out for the USB DAC.ESS Sabre32 Reference DACThe DAC is one of the most important components for digital audio playback. The ES9028-Q2M DAC chip used in the HA-2SE is the latest flagship mobile DAC developed by ESS Technology. With the ESS patented 32-bit Hyperstream DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented performance for mobile applications.Hi-fi Sound mai multe detalii aici
