Specifications

We always quote 'real world' performance figures (measured to the AES17 standard). Some companies choose to quote chipset performance, which is misleading, and here's why.

Mic Input

• Frequency Response: 20Hz - 20kHz +/- 0.1 dB. 
• THD+N: 0.001% (measured at 1kHz with a 20Hz/22kHz bandpass filter). 
• Noise: EIN > 125dB (128dB analogue to digital): measured at ~60dB of gain with 150 Ohm termination (20Hz/22kHz bandpass filter).
• Mic Gain: +10dB to + 55 dB
• Input Pad: ~-10 dB
• Phantom power switched in 2 x 4 channel groups (1-4 and 5-8)
• Maximum input level: +8 dBu (+17 dBu with pad on input)

Line Input

• Frequency Response: 20Hz - 20kHz +/- 0.1dB. 
• THD+N: < 0.001% (measured with 0dBFS input and 22Hz/22kHz bandpass filter). 
• Noise: -90dBu (22Hz/22kHz bandpass filter). 
• Line 1-8 Gain: -10 dB to +36 dB
• Line maximum input level: +22 dBu

Instrument Input

• Frequency Response: 20Hz - 20kHz +/- 0.1dB. 
• THD+N: 0.004% (measured with 0dBu input and 20Hz/22kHz bandpass filter). 
• Noise: -87dBu (20Hz/22kHz bandpass filter). 
• Instrument Gain: +10 dB to +55 dB
• Maximum input level: +8 dBu

Analogue Output

• Frequency Response: 20Hz – 20kHz +/- 0.2dB. 
• THD+N < 0.0010% (-100dB) (measured with 0dBFS input 22Hz/22kHz bandpass filter, un-weighted). 
• Nominal output level @ 0dBFS: 16 dBu, balanced

Digital

• A/D Dynamic Range 110dB 'A-weighted' (all inputs). 
• JetPLL™ Technology providing superb jitter reduction for class leading converter performance. 
• Clock Jitter < 250 pico seconds. 
• Sample Rate Clock Accuracy: +/- 20PPM. 
• Sample rates: 44.1kHz to 96kHz.
• Clock Sources: Internal and Word Clock.

Weight

• 3.6 kg / 7.93 lbs

Dimensions

• W = 484mm / 19”, H = 45mm / 1.8”, D = 265mm / 10.4”

FRONT AND REAR CONNECTIVITY

Analogue Channel Inputs:

• 2x Mic / Line / Instrument inputs on the front panel (Instrument selected via front panel button)
• 6x Mic / Line inputs on the rear panel. Switches automatically between Mic (XLR) and Line (TRS)

Analogue Channel Outputs:

• 8x Balanced 1/4" TRS Jack on the rear panel

Digital Channel Outputs:

• 2x ADAT Lightpipe (TOSLINK) outputs. Provides 8 channels per port (16 total) at 44.1 and 48kHz.
• Provide 4 channels per port (8 total) at 88.2 and 96kHz (S-MUX).

*Note that when running at 44.1 or 48kHz, the digital outputs are mirrored, providing outputs 1 - 8 on both ports.

Front Panel Indicators:

• 8x Five segment input LED meters (-42, -18, -6, -3 and 0dBFS)
• 4x Sample Rate LED's (44.1k, 48k, 88.2k and 96k)
• 2x Sync Source LED's (Internal and Word Clock)
• 'Lock' indicator LED
