Detailed Review of Key Features and Performance

Crystal Clear Mic Preamps

The star of the show on the Clarett OctoPre is undoubtedly the mic preamps. Focusrite uses high headroom, low noise input circuits paired with premium components like precision resistors and smooth dual-stage gain controls.

Focusrite Clar­ett Oc­to­Pre Pro­fes­sion­al Qual­ity 8-in/8-out ADAT Mic Preamp for Mu­sic Pro­duc­tion, with High Dy­nam­ic Range, Ul­tra-low Noise, and All-ana­logue Air

• The ideal Clarett I/O expansion kit: With eight Clarett mic pres, eight line outputs and ADAT interfacing, the Clarett OctoPre is the ideal way of adding inputs and outputs to any interface with ADAT I/O.
• The sound of transformer mic preamps: The eight specially-designed Clarett mic preamps include a switchable analogue 'Air' effect that imparts the sonic signature of the classic Focusrite ISA mic pre.
• 24-bit A-D and D-A conversion at standard sample rates all the way up to 192 kHz, with up to 118dB dynamic range A-D and 119dB dynamic range D-A (A-Weighted) to capture every nuance in recording and mixing.
• Feed the mic pres directly to a mixer in a live environment, simultaneously capturing your audio digitally via twin ADAT outputs. Or drive them from the ADAT inputs, giving you up to eight additional analogue outputs from your DAW.
• Dedicated switched insert points on every channel: Track through your favourite analogue outboard equipment such as compressors, gates and EQ with maximum flexibility via dedicated switched insert points with clip indicators on every channel.

The preamps deliver over 60dB of gain range and can easily capture subtle details, even with quiet sources. Engaging the “Air” mode adds warmth and presence through analog harmonic saturation, similar to Focusrite’s iconic ISA preamp design. It’s ideal for adding sheen to vocals and acoustic instruments.

Overall, the OctoPre’s preamps deliver exceptional transparency and flexibility for the price point. They outclass many budget interfaces and hold their own against preamps costing much more.

Versatile Connectivity

A major strength of the OctoPre is its versatile input and output connectivity. You get 8 combo XLR/TRS inputs that can handle both mic and line level sources. Use all 8 as transparent mic preamps, or toggle inputs 1 & 2 to instrument level for plugging in guitars and basses.

On the output side, you get stereo monitor outs on 1/4″ TRS jacks, S/PDIF stereo outs, and dual stereo headphone outputs. There’s also ADAT I/O for expanding with external mic pres or digital conversion.

With this well-rounded I/O suite, the OctoPre can slot seamlessly into just about any studio workflow or live rig. Focusrite really packed as much flexibility as possible into the chassis.

Cirrus Logic Conversion

Under the hood, Focusrite equipped the OctoPre with Cirrus Logic’s flagship A/D and D/A converters. These premium circuits deliver 114dB dynamic range on inputs and outputs, keeping your signals pristine whether recording or monitoring.

The OctoPre provides sample rates up to 24-bit/192kHz on all channels simultaneously. This high resolution captures subtle room ambience and spatial cues that lower sample rates miss.

Overall, the OctoPre’s conversion delivers exceptional transparency that brings out the most from high-end mics and outboard gear. The specs match or exceed interfaces costing twice as much.

Intuitive Control Software

Configuring the OctoPre is easy thanks to Focusrite’s Control desktop app. It provides one-click access to buffer settings, sample rate, clock source, and routing. You can remotely control the OctoPre from your computer without having to touch the hardware.

The app also enables “loopback” recording, allowing you to route audio from your computer apps straight into your DAW. For example, you can record podcasts or stream music while capturing the audio in real time. It’s an extremely useful feature for content creators.

Ideal Users for the Clarett OctoPre

With its excellent mic channels, flexible I/O, and clean conversion, the OctoPre is well suited for:

• Project studios – 8 tracks is plenty for singer-songwriters, podcasters, and YouTubers. The OctoPre provides pro-grade quality at a reasonable price.
• Commercial studios – The OctoPre works great as extra mic pres for large tracking sessions. You can expand via ADAT with Clarett or Red interfaces.
• Live sound – Front of house and monitor engineers will appreciate the rugged metal chassis, assignable outputs, and pristine preamps.
• Pro podcasters – Loopback recording, Air mode, and headphone cues are perfect for capturing podcasts with studio-quality sound.

Of course, the OctoPre can work seamlessly in virtually any audio production context. It’s an extremely versatile interface.

How It Compares to Other Interfaces

So how does the OctoPre stack up against the competition? Here’s a brief comparison to two popular 8-channel interfaces in the same price range:

• Audient iD14 – The iD14 has Audient’s flagship console mic preamps. It excels for vocals and acoustic instruments. The OctoPre offers more flexible routing and better DAC performance.
• PreSonus Quantum 2626 – The Quantum 2626 features tube preamp emulation and motorized faders. The OctoPre provides lower noise, Cirrus Logic conversion, and a better control software.
• Universal Audio Apollo Twin X – The Apollo Twin X has UA’s excellent analog emulations like Unison preamps. But the OctoPre gives you more physical inputs and LED meters at a lower price point.

Overall, the OctoPre holds its own against the competition by leveraging Focusrite’s excellent preamps and conversion. It punches above its weight class.
