The EHP-O2D incorporates both the award winning EHP-O2 portable headphone amplifier and the critically acclaimed E-DAC into one petite enclosure – the same enclosure as the EHP-O2!
The unit can be supplied either with an analogue signal via the 3.5mm input jack on the front panel or can be fed with a digital via the mini USB socket on the rear of the unit.
A 1m USB to mini USB cable as well as a 1.2m mini jack to mini jack cable is included to get you started. The box also contains an AC power adapter suitable for your region and 4 self adhesive rubber feet so that the unit sits comfortably on your desk.
The headphone amplifier section has been designed from the ground up to offer some of the best, if not the best, specifications and hi-fi functionality on the market today. This has been accomplished by months of development using top of the range audio testing equipment to fine tune and carefully select the most optimum design, layout and components. The specifications achieved speak for themselves. It is powered by the included AC adapter suitable for your region.
Technical specifications of amplifier section:
- THD @ 1kHz: 0.0017%
- Noise level (ref 400mV): -105dB
- Power output @ 33Ω : 641mW
- Crosstalk: 65dB
- Channel balance: 0.6dB
- Output impedance: 0.5 Ohms
- Dimensions (W x H x L): 108.5mm x 30mm x 82mm
The DAC module is designed according to the same principles as the award EHP-O2 portable headphone amplifier and sports equally stunning performance.
This high end DAC is based on the TE7022L UAC1 engine ES9023 24 bit DAC chip. It supports 16 bit and 24 bit at sample rates of 44.1kHz, 48kHz and 96kHz. The on-board filtered power supply ensures that noise is practically non-existent. The DAC is not clocked by the USB port/computer, instead using a high quality on board crystal controlled oscillator which further improves overall performance. The input signal and power is supplied via the USB input on the rear of the unit.
Technical specifications of the DAC section:
- Distortion: <0.005%
- Dynamic range: >110dB A-Weighted
- Audio formats: 44.1kHz, 48kHz & 96kHz @ both 16 bit and 24 bit
- Interface: USB Audio Class 1
- Computer compatibility: Windows, Mac, Linux
- Line output: 2Vrms
Lead time: approx. 3 weeks from date of order, plus transit time.
