Combining design elements from the company's other products, the Ensemble Thunderbolt Audio Interface from Apogee builds upon their reputation for high-gain preamplifier design and improves upon their transparent analog-to-digital and digital-to-analog conversion with the addition of an ultra-low latency 1.1 ms (96 kHz / 32 buffer) 32-bit playback Thunderbolt signal path.

For inputs, the 1U rackmountable interface features eight microphone preamps with up to 75 dB of available gain using the company's Advanced Stepped Gain Circuitry - four rear panel XLR-3F connectors and four rear panel ¼" TRS/XLR-3F combo connectors. The preamps include line level Input channels 1 and 2 also included 1/4" send and return loops.

The inputs include FET-based Soft-Limiting which can be enabled in the Apogee Control software and prevent digital clipping by instantaneously rounding off transient peaks before hitting the analog-to-digital converter. This allows several more decibels of apparent level to be recorded while also subtly proving an analog-tape-like warmth to the sound. Inputs can be selected using the front panel's grid of soft LED illuminated buttons. Pressing and holding the input select buttons will adjust parameters such as input type, +48v phantom power, Soft Limit, grouping, polarity invert, and hi-pass filtering.

The front panel features two Guitar I/O channels with class-A JFET inputs in a bootstrapping circuit design to reproduce the feel of vintage tube amplifiers and preserve the tone and high frequency response of connected instruments by providing an ultra-high impedance load. Beneath the front panel guitar inputs are a pair of dual mode re-amp outputs for connecting to external effect processors such as stomp boxes or guitar amplifiers.

The dual mode switching allows you to easily record your direct guitar signal while also listening through an amplifier. You can then play the recorded guitar signal back through the amplifier to adjust tonality and microphone placement.

A built-in microphone capsule within the interface can be used for archiving your session, recording a crushed room sound when tracking drums, or for talkback when tracking musicians. Rear panel Word Clock IN and OUT connectors enable syncing other digital audio gear to the interface's high quality master clock.

For outputs the interface features 16 rear panel analog outputs in the form of two balanced 1/4" TRS monitor outputs and eight balanced line outputs on a D-Sub 25-pin connector. The front panel features two PurePower headphone outputs with separate volume controls for monitoring mixes. Monitoring can be configured between the two 1/4" outputs, one of three stereo speaker sets, or a 5.1 surround system.

The speaker and headphone levels are controlled with the dedicated knobs on the unit's front panel OLED display or with your Mac's volume controls. Four configurable buttons labeled A, B, C, and D can be assigned using a software drop-down menu to functions such as muting outputs, dimming outputs, engaging talkback, engaging a speaker set, or clearing meters.

With the addition of the unit's rear panel S/PDIF I/O and dual ADAT I/O connectors, the interface is capable of a total 30 inputs and 34 outputs. The interface also features optional direct hardware monitoring through the Apogee Control software, with only 0.6ms of latency (at 96 kHz with a 32-sample buffer).

The extraordinarily round trip latency of the converter is made possible by a proprietary Thunderbolt driver that was built from the ground up for Mac OS X Mavericks. Even in sessions that require higher buffer settings for DSP requirements, the ultra-low latency of the interface prevents the compromise between power and speed.

The driver uses a 32-bit signal path from the output of the DAW into the unit's ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter eliminator for low distortion audio with significant headroom and dynamic range. The interface also employs a Direct Memory Access (DMA) engine to more efficiently read and write data directly to Mac memory independently of the CPU.

Directly reading and writing a 32-bit signal from memory increases the driver's efficiency, lowers latency, provides a higher resolution signal, and frees up more CPU power for plug-ins. Apogee-designed power regulators are used throughout the interface's mic pre, A/D, and D/A circuitry for ultra-low noise operation.

The Ensemble Thunderbolt features the Apogee Control software with the Essentials Control Strip window, which offers extensive flexibility to customize your workflow and adapt to your creativity. The software lets you connect two Ensemble Thunderbolt interfaces to your Mac to double your analog inputs and outputs, and connect any Apogee Element interface to expand your system with Ensemble-quality I/O.

The interface's dual rear-panel Intel Thunderbolt ports allow you to connect multiple high bandwidth peripherals to your Mac such as hard drive arrays, video capture devices, and Thunderbolt monitors with up to 4k resolution from a single port. The interface is designed in California and assembled in the U.S.A.
