M-Audio Profire 610: Not good for Re-amping
Wednesday, July 1st, 2009Until today I thought the M-Audio Profire 610 and 2626 were the same with different I/O count. Perhaps this is my own ignorance, but I’m sure I’m not the only one thinking this.
On a forum a member was having trouble re-amping with his 610. The 2626 owners have no problems re-amping so I decided to compare the specs on the Line outs of each interface.
Profire 2626 Line Outputs (Balanced)
- Frequency Response +/- 0.1dB, 20Hz to 22kHz
- +/- 0.6dB, 20Hz to 80kHz (192kHz)
- Dynamic Range 110dB, A-weighted
- Signal-to-Noise Ratio -110dB, A-weighted
- THD+N 0.0013% (-98dB), 1kHz, -1dBFS
- Crosstalk < -110dB @ 1kHz
- Maximum Output Level +20.2dBu balanced, typical
- Output Impedance 300 Ohms, balanced
Profire 610 Line Outputs (Balanced)
- Frequency Response +/- 0.1dB, 20Hz to 22kHz
- +/- 0.2dB, 20Hz to 80kHz (192kHz)
- Signal-to-Noise Ratio -108dB (A-weighted)
- Dynamic Range 108dB (A-weighted)
- THD+N 0.0016% (-96dB) @ -1dBFS, 1kHz
- Crosstalk < -105dB @ 1kHz
- Maximum Output Level +15.9dBu balanced, typical
- Output Impedance 940 ohm balanced
So What?
With the Profire 610, you won’t be able to properly re-amp, especially if you’re hoping to get Hi-Gain tones from your amp. You will distort the D/A before getting enough level into your re-amp box. The Profire 2626 does not have this issue because it operates at a higher level.
Those aren’t the only differences, the input stage of the 610 isn’t as good as the 2626 either. It’s really unfortunate, the 2626 is a great interface, but it’s not portable, if the 610 had the same specs in a smaller size it would be really great.
