Introducing the all new Symphony ControlSymphony Control SoftwareSymphony Control software for Mac, is designed specifically for Symphony I/O Mk II audio interfaces. Symphony Control has been built from the ground up and replaces Apogee’s Maestro software for Symphony I/O Mk II users. Symphony Control delivers all the functionality of Maestro in a new, highly customizable user interface along with innovative new features like Talkback functionality, the simplified “Essentials” control window and an FX Send mixer feature, recently introduced as part of the Element Control software.Apogee Control Hardware Remote AccessorySymphony Control also provides compatibility between Symphony I/O Mk II audio interfaces and the Apogee Control hardware remote accessory. Apogee Control gives you instant access to input and output levels using the large Symphony-inspired Control knob and 3 control knob focus buttons, plus direct access to a wide range of software functions using the 8 user-configurable hardware buttons. Apogee Control hardware remote connects directly to your Mac using the included USB cable.Multi-unit support for up to 64 channels of I/OWith the introduction of Symphony Control, customers can now use 2 Symphony I/O Mk IIs  simultaneously for up to 64 channels of I/O over a Thunderbolt connection to their Mac. Symphony I/O Mk II combined with Logic Pro on a Mac delivers the most advanced native workstation available with superior quality high-channel count recording at incredibly low latency.Standalone modeStandalone 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 SystemsConnect 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 WorkstationsMay use a third party ADAT or AES PCI interfacing card to use Symphony I/O MkII converters on a Windows Machine.Standalone ConverterStandalone 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.Mk II Sound Quality–New 8×8 and 16×16 ModulesLike 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.Audiophile-Grade Headphone Monitoring with Constant Current DriveSymphony 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 TechnologyESS 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 HearApogee 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.Optional 8 Channel Mic Preamp ModuleSymphony I/O Mk II’s mic pre module includes 8 uniquely designed channels of 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 unprecedented gain range of 0-85 dB. 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.Specifications:Highlights:
