Ensemble Thunderbolt™ is the best sounding all-in-one audio recording interface for Mac. With ultra-low latency performance, comprehensive studio functionality and legendary Apogee quality, Ensemble is the ideal choice to meet the diverse demands of the professional home or commercial studio. Ensemble features premium Apogee AD/DA conversion, 8 Advanced Stepped Gain™ mic preamps, monitor controller functionality including talkback, front panel Guitar I/O, two headphone outputs and digital connectivity for a total of 30 x 34 I/O.

Front Panel Guitar I/O with Class A Input and Re-amping
2 front panel Guitar I/O channels with class A JFET inputs and dual mode re-amp outputs capture pristine direct signals and make re-amping effortless.

Ultra-low Latency and Advanced CPU Efficiency
At 1.1ms, Ensemble’s Thunderbolt driver offers the lowest round-trip latency performance available. And Ensemble’s revolutionary DMA engine provides incredible CPU efficiency allowing you to leverage the full power of your Mac and native plugins.

Creative User Interface and Monitor Control
Ensemble’s groundbreaking front panel marks the evolution of Apogee’s simplified user interface, featuring total monitor control and a built-in mic for talkback.

Measurably Superior AD/DA Conversion and Mic Preamps
Ensemble’s AD/DA conversion and microphone preamps are modeled after Apogee’s flagship Symphony I/O, with sound quality a step up from the award-winning Duet and Quartet.

Inputs & Outputs

Guitar I/O
Directly connect your guitars & other instruments to Ensemble using the 2 front panel ¼” inputs.

8 Analog Inputs
Connect up to 8 microphones or a combination of instruments, external mic preamps, and other analog audio devices.

10 Analog Outputs
2 balanced monitor outputs on ¼” TRS connectors & 8 balanced line outputs on 1 D-Sub 25-pin connector.

2 headphone outputs
Drive 2 sets of high impedance headphones louder than you’ll ever need.

Built-in Microphone + Talkback
nstantly capture your inspirations, keep an audio archive of the session, or record a “crushed room” sound when tracking drums. Most importantly, the built-in mic may be used for talkback.

2 Analog Inserts
Easily integrate your favorite analog compressor or EQ, in mono or as a stereo pair, into your recording chain with separate ¼” balanced send and return connector for each channel.

Digital I/O
Up to 18 channels of digital I/O, in ADAT, SMUX, S/PDIF optical and S/PDIF coaxial formats, to easily integrate expanders, hardware synths and digital effects.

Word Clock
Use Ensemble as the master clock to take advantage of Apogee’s superior built-in clocking technology.
