Greetings, Head-fi! This is Grace from AAW. Ever since the rumor of the new iPhone’s 3.5mm port removal, we’ve been working on an MFi-certified DAC amplifier in several designs and prototypes for some time.
It’s my pleasure to finally introduce Accessport: High-resolution DAC/amplifier designed for iPhone 7, MFi-certified. We’ve been working closely with the guys at ADVANCED SOUND to develop and to bring this product to the market. Also we did not forget the Android community and will make Accessport available with microUSB and USB Type-C as well.
We have completed our T1 prototype of our Accessport and we are excited to share the details with you guys at Head-fi, first-hand. We will be launching the Accessport on Kickstarter and you can find the following details of the product:
Specification:
Digital Input: Lightning/USB Type-C/Micro USB
Frequency Response: 10Hz~45kHz
Bit Depth: 24bit
Sampling Rate: 96kHz with oversampling
SNR: (A-Weighted) -122dB
THD: <0.01%
Output impedance: <1Ohm
Power Output: 40mW to 16Ohm load
Lightning Receptacle with Charging
Through Phone Call Function(MFI only)
Apple MFI Approved
We love the Head-fi community and we want to hear first from you lot about what you think of our Accessport.
What other way to share the experience but to start a giveaway! We will be giving away 10pcs Accessport. You will be entered into the giveaway for the first hand experience of our Accessport with the following conditions:
1. Post an initial reaction to this thread
2. Share this thread on your Facebook
We look forward to your participation. Once you receive the Accessport and if you like it, a review is in order
Thanks for reading!
Sincerely,
Dr. Grace Wang
