Input level ..................................... 0.5 V to 5.0 Vp-p
Output level .................................. TTL: 5.0 Vp-p, unterminated
Input impedance .......................... 510 ohms
Output impedance ...................... 75 ohms
Max. propagation delay .............. Horizontal 90 ns, vertical 160 ns
Max. rise/fall time ....................... 4 ns
Polarity .......................................... Positive or negative (follows input)
Audio
Routing
MVX 44 VGA A ................ 4 x 4 stereo matrix
MVX 48 VGA A ................ 4 x 8 stereo matrix
MVX 84 VGA A ................ 8 x 4 stereo matrix
MVX 88 VGA A ................ 8 x 8 stereo matrix
Throughput gain .......................... Adjustable. At default (when input gain is set to 0 dB and output level is set
to “Pro”), overall gain is 12 dB for balanced output. The gain range is -6 dB
to +22 dB for balanced output when the output level is set to “Pro”.
Frequency response ..................... 20 Hz to 20 kHz, ±0.2 dB
THD + Noise ................................ 0.05% @ 1 kHz, 0.3 % @ 20 kHz at nominal level
S/N ................................................ >90 dB at maximum output (unweighted)
Crosstalk ....................................... <-65 dB @ 20 kHz, <-80 dB @ 1 kHz or below 60 Hz
Stereo channel separation .......... >80 dB @ 1 kHz, >55 dB @ 20 Hz to 20 kHz
Audio input
Number/signal type
MVX 44/48 VGA A ......... 4 stereo, unbalanced
MVX 84/88 VGA A ......... 8 stereo, unbalanced
Connectors
MVX 44/48 VGA A ......... 4 female 3.5 mm stereo mini jacks: tip (L), ring (R), sleeve (GND)
MVX 84/88 VGA A ......... 8 female 3.5 mm stereo mini jacks: tip (L), ring (R), sleeve (GND)
Impedance .................................... >18k ohms unbalanced, DC coupled
Nominal level ............................... -10 dBV (316 mV) (default), but also compatible with +4 dBu (1.23 V),
0 dBu (0.775 V), -20 dBV (100 mV)
Maximum level ............................ >+12 dBV (4 V), (unbalanced) at 1%THD+N
Input gain ...................................... –18 dB to +10 dB, adjustable per input; default = 0 dB. (this is referenced to
the internal bus signal level. It can be verified by measuring the unbalanced
output when the output level is set to “Consumer”.)
0 dBu = 0.775 V, 0 dBV = 1 V, 0 dBV 2 dBu.
