Standalone mode
Symphony I/O Mk II setup screen for Standalone mode
Standalone Routing lets you setup and use Symphony I/O Mk II without a computer. From the front panel touch screen you can set up Symphony I/O Mk II for use in these situations and more:
Hi-Fi Systems
Connect Symphony I/O MkII to a Blu/Ray, CD Player or Power Amp for high end speakers. Symphony I/O Mk II is also an ideal high-end headphone amp.
Windows Workstations
Use Symphony I/O mkII on a Windows computer with Dante™, Pro Tools® HD, Waves SoundGrid®, or as a Standalone converter with a third party ADAT/AES PCI interfacing card.
Standalone Converter
Standalone AD/DA converters can be used alongside other digital gear: To expand other interfaces, to connect to live or studio digital consoles, to connect to broadcast equipment. With Standalone mode you can also bypass the converters of your existing gear.
Why do I need a good AD/DA converter?
Whether you record with a vintage Neve console, the best Neumann microphones or colorful mic preamps, a high quality AD converter is imperative to capture every nuance of your analog gear into your DAW. Without this, you will miss many of the subtleties and details that simply cannot be added back later with plugins. Similarly, the DA stage is essential to your perception of the recorded audio tracks. When mixing, regardless of what speakers you are using, if the converter is masking or having any effect on your audio, you could end up overcompensating with EQ, compression or other effects and failing to address other problematic details.
With Symphony I/O Mk II, you will hear more definition in each track and instrument of the mix, making it easier for you to make intelligent adjustments and achieve the ideal balance. Tracks will blend more harmoniously and mixing will simply be easier. The high end will be clear and not as brittle while the low end will be tighter than ever and more defined. This sort of unmatched audio quality can be noticed and appreciated by any listener.
Apogee Engineering Advantage
For over 30 years, Apogee has consistently
redefined the state of the art in digital audio hardware design. We never rest on the laurels of our previous award-winning products – we’re constantly evaluating the latest technological developments in analog and digital components, platform connectivity and user interface advances to design better performing, intuitive products that meet the needs of any audio professional.
As an example of the Apogee Advantage, Symphony I/O Mk II uniquely employs a fully differential op-amp as a fundamental building block throughout its analog circuits. The very latest iterations of this technology offer astounding performance – vanishingly low noise and distortion, lightning-fast slew rate and out-sized current output capability, all in a power efficient and small package. These components offer performance that’s orders of magnitude superior to what’s found in most competitive audio interfaces, and are an important factor in Symphony I/O Mk II’s ability to offer up to 32 channels of state-of-the-art conversion in one 2U package at an incredible price per channel value.
Mk II Sound Quality- New 2x6SE, 8×8 and 16×16 Modules
Like every flagship product we’ve introduced, Symphony I/O Mk II benefits from on-going expertise that constitutes the Apogee Engineering Advantage, once again pushing forward the state-of-the-art.
Symphony I/O Mk II includes the most refined analog-to-digital converter we’ve ever designed. The analog stage uses the same fully differential op-amps as found in the original Symphony I/O, but now in a circuit precisely streamlined to provide the most transparent path to the A/D stage possible. A Dual Sum A/D stage – where two conversion stages are summed for each analog channel – offers the lowest distortion and greatest dynamic range of any A/D converter we’ve ever designed – you get digital recordings that are true to your analog inspiration.
Symphony I/O MK II’s D/A section has been optimized with a more powerful, robust analog output driver. This newly designed high current, low impedance circuit is capable of driving virtually any input with absolutely no decrease in performance, regardless of the load presented by the connected gear. This becomes especially important when connecting vintage gear with difficult load impedances and elevated operating levels, sometime over long cables – Symphony I/O MK II maintains fidelity and punch.
Symphony I/O Mk II features a single ultra high-fidelity DAC and headphone amplifier featuring Apogee’s Constant Current Drive technology, first introduced in the Apogee Groove. This unique approach to headphone amplification dynamically compensates for the nonlinearities of any connected headphones, providing massive power while maintaining extremely low distortion and linear frequency response.
Includes ESS Sabre32 DAC Technology
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.
A Difference You Will Hear
Apogee is an award-winning industry leader in digital recording technology with over 30 years of experience. Preferred by recording pros around the world, Apogee products like Duet, Quartet, Ensemble and Symphony I/O have been instrumental in creating countless GRAMMY® and OSCAR® winning recordings and have set the industry standard in professional recording for over two decades. Symphony I/O Mk II is built solidly on this reputation.
Symphony I/O mkII’s mic pre modules include Apogee’s Advanced Stepped Gain Architecture™, in which the circuit is dynamically optimized to provide superior bandwidth, ultra low noise and nonexistent distortion across the entire gain range. Whether recording powerful drums, dynamic vocals or delicate strings, your recordings retain the full impact, intricate detail and lifelike dimension of the original performance.
Symphony I/O Mk II’s Mic pre module also includes 8 channels of digitally-controlled analog inserts, so that outboard processors like EQ and compression may be inserted into the signal path between the mic preamp and the A/D conversion stage effortlessly. Because the inserts are digitally-controlled from Symphony Control software, any insert can be assigned to any input channel – there’s no need to physically reconnect your outboard equipment to a different insert channel.
