M-Audio ProFire 610 Audio Interface

The ProFire 610 from M-Audio brings you the preamp technology that audio professionals trust for clean, transparent sound. Each preamp delivers low distortion and an extremely high signal-to-noise ratio - for pristine audio fidelity right from the start of your signal path. In addition to exceptional sound, each preamp has a generous 73dB gain range, 20dB pad and 48V phantom power.

Interactive control panel

ProFire 610 features an onboard DSP mixer, giving you an extra level of flexibility and improving the overall performance of your system. Use the software control panel to create custom configurations for different recording setups, then save the settings and instantly recall them later.

You can set up five unique stereo mixes sourced from any of the hardware inputs and software returns simultaneously - ideal for assigning separate monitor mixes to multiple musicians. The onboard DSP mixer also enables you to monitor while tracking, just as you would with a hardware mixer.

High-definition sound and solid performance

The ProFire 610 is designed using carefully selected components, including premium A/D-D/A converters that keep your audio signal uncoloured and true to any input source. The electronic circuitry is engineered to provide an optimal signal path between input and output, resulting in extremely clean recordings that capture every nuance of your performance.

It features critically acclaimed JetPLL jitter-elimination technology for stable synchronisation and exceptionally low audio band jitter. ProFire 610 delivers solid performance and reliability at sample rates up to 24-bit/192kHz.

User-assignable master volume control

The ProFire 610 interface delivers flexible control over output levels, allowing you to create a monitoring setup tailored to your specific needs. The master volume knob can be assigned to attenuate all output pairs simultaneously - ideal for controlling a 7.1 surround mix.

Standalone operation

ProFire 610 also functions in standalone mode, allowing you to use its premium preamplifiers without connecting to a computer. Just power up ProFire 610, connect your microphones or instruments, and the preamp outputs automatically route to analogue outputs 1 and 2, and S/PDIF. You can also connect digital devices via S/PDIF and convert to analogue. This unique feature makes ProFire 610 ideal for both front-end pre-amplification and A/D-D/A conversion.

Best-in-class I/O

ProFire 610 features greater connectivity than any other interface in its class. Four unique analog inputs, eight analogue outputs and stereo digital S/PDIF combine to form an impressive 6-in/10-out channel configuration. Easily access analogue channels 1 and 2 via XLR/TS combo jacks on the front panel. Connect line-level instruments and effects processors to analogue channels 3 and 4 via TRS.

Use the eight 1/4" TRS balanced line outputs and digital S/PDIF to monitor and interface with outboard gear. Connect keyboards and outboard MIDI hardware to the 1 x 1 MIDI interface. The two front-panel headphone jacks are sourced separately with independent level controls for additional cue mixing flexibility. ProFire 610 allows you to enjoy full 24-bit/192kHz operation on all inputs and outputs simultaneously.

6 inputs including:

• 2 XLR/TS combo jacks for mics or instrument level inputs
• 2 ¼" TRS balanced line inputs
• Stereo S/PDIF in

10 outputs including:

• 8 ¼" TRS balanced line outs
• Stereo S/PDIF out
