The Apogee Electronics Symphony I/O Mk II Thunderbolt Audio Interface with Special Edition 2x6 Analog I/O and 8x8 Digital I/O is an audio interface designed to deliver high-performance A/D and D/A conversion at up to 192 kHz for mixing and mastering engineers in personal, project, and commercial studios. The included 2x6 SE I/O card features stunning dynamic range with low distortion and noise for mastering-grade sonic quality.

Its analog I/O includes two inputs on XLR 3-pin jacks and six outputs on a DB25 connector. Additional XLR, TOSLINK optical, and RCA coaxial jacks provide connectivity for AES/EBU, ADAT, and S/PDIF digital inputs and outputs. The chassis utilizes Thunderbolt connectivity for high-speed data transfer rates and compatibility with Core Audio software. Its front panel presents a TFT touchscreen display, multi-function control knob, and convenient 1/4" stereo headphone output.

Apogee Electronics Symphony I/O Mk II Chassis (Thunderbolt)

The Symphony I/O Mk II from Apogee Electronics is an advanced, flexible multi-channel audio interface featuring the newest flagship AD/DA conversion, modular I/O (up to 32 inputs and outputs), and an intuitive touchscreen display. The chassis provides two I/O Module slots for a variety of digital audio conversion options that form the interface side of the Symphony I/O Mk II. The front-panel touch screen offers convenient access to nearly every setting including sample rate, clock source, headphone & speaker output levels, meters for all I/O and section navigation, as well as input levels, digital I/O, and configuration settings.

The rear panel provides access to the two I/O Module slots that are capable of a combined thirty-two channels of input and output, while the two Thunderbolt connectors ensure compatibility with newer Mac computers. Also included are Wordclock I/O connectors & termination, an option card slot, and a quiet digitally-controlled fan to keep everything running cool.

The Symphony I/O Mk II features a single ultra-high-fidelity DAC and headphone amplifier  with Apogee's Constant Current Drive technology, which was first introduced in the Apogee Groove. The headphone amplifier dynamically compensates for non-linearities of any connected headphones, providing massive power while maintaining extremely low distortion and linear frequency response.

The optional five I/O Modules allow the user to choose from standard configurations, or customize the following – channel count, analog to digital input, digital to analog output, microphone preamps (requires an analog card), and digital I/O.

Fun for dogs
Color: Green/Alligator, Size: Small
Smaller than I expected, but the two little dogs love it! They love shaking it, making it squeak, tugging it against each other & chasing it when I throw it to fetch. They often sleep laying on it.

WEIRD feature - requires a water bottle
Color: Cow, Size: Large
Cute, but buyer beware. Maybe the description said this, but who would think to read for this.... You have to insert an empty bottle (like an old water bottle) for it to make the crinkle noise. There is a velcro spot at the base where you can open it and insert the water bottle for the noise factor and your dogs entertainment. I've yet to do that, but feel like my dog is gonna figure out the velcro and get the bottle out in no time. Seems like a waste of money. I could just give her an empty water bottle without the toy for free.

Best dog toy!
Color: Multicolor/Alligator & Wild Duck, Size: Medium, Color: Multicolor/Alligator & Wild Duck, Size: Medium
Best dog toy! Most dog toys lady maybe a week or less but this one has been going strong for almost 2 months. Both the squeekers still work on both toys i purchased. My vizsla loves ti squeek and carry it around. We added an empty water bottle in the pocket cavity for some extra fun! Yes, we are still on the same water bottle! Fantastic durability.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.
