With emulations of vintage British and American mic preamps, DSP/native Apogee FX plug-ins, and multiple zero-latency plug-in workflows, the Symphony Desktop puts you in complete control of your tone. Thanks to its color touchscreen and large control knob, the Symphony Desktop provides easy operation and comprehensive visual feedback.

Record mic-, line-, or instrument-level signals through the variable-impedance, high-gain preamps and use the monitor outputs and assignable headphone jacks for listening to the main mix or an alternate source. Expand your setup by connecting external digital equipment to the optical TOSLINK ports, which support 8-channel ADAT or 2-channel S/PDIF protocols.

Included Apogee FX Plug-Ins
Symphony ECS Channel Strip: EQ, compressor, and saturation tuned by Bob Clearmountain (includes native and hardware DSP versions)
Symphony Reverb (includes native version)
Pultec EQP-1A, Pultec MEQ-5, and Mod EQ-6 equalizers (hardware DSP versions)
Opto 3-A and Mod Comp compressors (hardware DSP versions)
Included Mic Preamp Emulations
British Solid State: Class-A console sound inspired by the Marinair round can input transformer and discrete transistor design of the Class-A Neve 1066 mic preamp
American Tube: lush, vintage-style tone inspired by a 1950s Ampex 601 preamp that was restored and modded for lower noise and greater dynamic range
Flexible Plug-In Workflows
Symphony ECS gives you the full range of Apogee workflow options. For zero latency tracking, you can print through it as you record or set up a DualPath Link for monitoring and print later when you mix. Or simply use Symphony ECS as a native plug-in in your DAW, no Apogee hardware required.
