The OPPO HA-1 Headphone Amplifier, DAC & Pre-Amplifier.Drawing upon the proven circuit design of the award-winning OPPO BD players, the HA-1 combines an uncompromising Class A balanced power amplifier section with the performance of the ESS 9018 Sabre32 Reference DAC.OPPO designs the HA-1 headphone amplifier with the same universal approach as our Blu-ray players. The HA-1 is a high performance headphone amplifier, and it doubles as an asynchronous USB DAC, a stereo pre-amplifier, a digital audio dock for mobile devices, and a Bluetooth audio transport. Its fully balanced design and numerous inputs ensure the best in fidelity and versatility.SpecificationsDesigns and specifications are subject to change without notice:General Dimensions (W x H x D)10.0 x 3.1 x 13.1 inches, 254 x 80 x 333 mmMass13.0 lbs, 5.9 kgPower SupplyAC 110-120 V~ / 220-240 V~, 50/60 Hz auto-sensingPower Consumption70 W (operation), 0.5 W (standby)Trigger Input3.5 V – 15 V, 10 mA minimumTrigger Output12 V, 100 mA maximumOperating Temperature41 °F - 95 °F, 5 °C - 35 °COperating Humidity15% - 75% No condensationRecommended Headphone Impedance32 ohm – 600 ohmBalanced Headphone Jack Output (XLR-4) Pin order1: L+, 2: L-, 3: R+, 4: R-, Shell: GND6.35 mm Headphone Jack Output Pin orderTip: L, Ring: R, Sleeve: GNDXLR Balanced Audio Input Input Impedance15k ohmMaximum Input Level18 Vrms, +27.3 dBu (0 dBu = 0.775 Vrms)RCA Stereo Audio Input Input Impedance10k ohmMaximum Input Level9 Vrms, +21.3 dBu (0 dBu = 0.775 Vrms)Coaxial, Optical, AES/EBU Digital Inputs Input FormatStereo PCMSampling Frequencies44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz,176.4 kHz, 192 kHzWord Length16-bit, 24-bitUSB DAC Audio Input (USB B Type) Input FormatStereo PCM, Stereo DSD (DoP v1.1 or native)PCM Sampling Frequencies44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz,176.4 kHz, 192 kHz, 352.8 kHz, 384 kHzPCM Word Length16-bit, 24-bit, 32-bitDSD Sampling Frequencies2.8224 MHz (DSD64), 5.6448 MHz (DSD128),11.2896 MHz (DSD256, native mode only)ProfileUSB 2.0, USB Audio 2.0Mobile USB Audio Input (USB A Type) Input FormatStereo PCMPCM Sampling Frequencies44.1 kHz, 48 kHzProfileUSB 2.0, USB Audio 2.0VBUS Power Output+5 V, 2.1 ABluetooth Audio Input StandardBluetooth 2.1+EDRProfileiAP, SPP, AVRCP, A2DPAudio Transmission FormatSBC, aptX
