USB Audio Interface ขนาด 2-in/4-out แบบพกพาเอาไว้สำหรับควบคุมการบันทึกเสียง ระดับ Studio มืออาชีพ ด้วยความละเอียดสูงถึง 24-bit/192kHz โดยสามารถใช้ควบคุมได้ทั้ง Mac และ iPad ที่สร้างขึ้นมาสำหรับนักดนตรี รวมไปถึงโปรดิวเซอร์ที่ต้องการคุณภาพเสียงที่ดีที่สุด The distortion driving the 30 Ω-rated Ultrasone Edition 8 is much more than driving 600 Ω loads, but nothing to worry about. What is notable is the rise in low-frequency distortion, again caused by the non-zero output impedance of the amplifier interacting with the very real load of these dynamic headphones. At 0.1%, I'm not worrying about it; headphones have a lot more distortion than that at 50 Hz. Duet caught me immediately with its crystal clear AD/DA conversion. The sound is absolutely fantastic. Being a Logic 9 and Logic X user mostly, Apogee already has a place inside the Logic DAW option menus to control the Input levels. The dedicated Headphone input is also commendable. Choosing the right audio interface is a serious endeavor. You’ll likely be spending hundreds of dollars, and it is imperative to get one that fits your needs.

Compare this to my other DAC and CD player tests to see the relative effects of intermodulation distortion and other noise. This Apogee is a bit cleaner than the Sony SCD-XA777ES. Note that the Sony chart is at a different vertical scale; the important part is that the largest spur from the Apogee is about -112 dBFS, while it's about -110 from the state-of-the-art Sony XA777ES. Then open Main Stage and select the Apogee Duet as the interface, choose input 1 as your in, and out 1 as your output (switch to mono). Regardless of the Apollo model in question, the quality and amount of features you get is quite impressive, whereas the Duet 3 is a more limited interface (albeit a high quality one, just like the Twin). The set-up is a breeze install the drivers and Apogess Maestro control panel that lets you select levels, inputs, routing, whether audio will be send straight to the hardware outs or from the recording software.While ESS Sabre32 DAC has been widely recognized and employed in the audiophile community as the next step in converter technology, Apogee is one of the first pro audio manufacturers to employ this DAC in an interface designed for audio and video professionals. ESS Sabre32 DAC technology, as employed in Duet 2 , Duet for iPad & Mac , Quartet and Symphony I/O , is one ingredient in the Apogee Engineering Difference. The benefits of the ESS Sabre32 DAC include: ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequalled dynamic range, ultra low distortion, and unmatched audio clarity free from input jitter. You tap the knob to select which level you are going to change: Input 1, Input 2, Speaker or Headphone. RME also included a plug-in bundle that comes with Scuffham’s S-Gear, a flexible guitar amp simulator that was created by a former product designer from a legendary British amplifier company (try and guess which one).

As a professional piece of audio equipment, it only runs with professional grade (Apple) computers. It won't work with junk like windows, Barbie or other hobby or toy computers. The input gain never drops to off or mute, only to very low. If you want to fade to silence, do that elsewhere. Regarding connectivity, the Twin is a Thunderbolt 3 audio interface. Thunderbolt 3 also happens to be the most notable upgrade for version three of the Duet.

Legendary Sound Quality, Total Portability and Hardware DSP all Come Together in a Beautiful New Design On the other hand, the Duet 3 is easier to use, and you’ll be recording in no time compared to the Apollo Twin X. Where They Differ

Output noise: -94.6 dBV A-weighted, or 111.85 dB SNR, or 18.3 effective bits. (Effective bits = (SNR - 1.72 dB) / 6.0206.)For those who are considering a small interface for traveling, the Duet 3 ships with a travel case that protects it, fits it snugly, and allows for easy and safe transportation. Sample Rate, Connectivity and Sound analog inputs with world-class mic preamps and selectable 48v phantom power for connecting microphones, instruments or line-level devices. Missing: No TOSLINK, Coax or AES digital inputs or outputs. For professional computers only (MacBook, MacBook Pro, Mac Pro, Mac Mini, iMac, etc.; no windows).
