£1269.31 18 in / 18 out 192 kHz 24 bit 0.4 ms ADC / 0.15 ms DAC (converter latency); TotalMix direct monitoring down to 0.79 ms measured roundtrip at 44.1 kHz 2

Compact half-rack USB/FireWire interface with two digitally controlled mic preamps, four front instrument/line inputs and ADAT/SPDIF/AES digital I/O; supports up to 18×18 channels (44.1/48 kHz) and 24-bit/192 kHz conversion with RME's TotalMix FX and very low converter latency. Suited to mobile and project-studio users who need high-quality conversion, extensive routing and ultra-low latency monitoring in a small footprint.

★ Ideal for

Because it is a half-rack, bus-powered-capable (with external PSU) unit offering 8 analog I/O, 2 mic preamps, and full 24-bit/192 kHz support with very low converter latency, the UCX is one of the most compact and portable Firewire-compatible Fireface interfaces.

RME Fireface UFX
US
£2389.94 188 192000 24 4

The RME Fireface UFX is a high-end multichannel USB audio interface offering up to 188 simultaneous I/O channels, 24-bit/192 kHz conversion, TotalMix FX routing/DSP and direct USB recording. It features multiple digital formats (MADI, ADAT, AES) alongside analog I/O and is built for professional studios and live facilities requiring large channel counts and reliable clocking.

★ Ideal for

Not ideal - its large 188-channel I/O and rackmount size make it unsuitable for the most compact portable Firewire interfaces; it suits users needing a high channel-count stationary studio interface with USB 3/MADI connectivity.
