SPECIFICATIONS
OUTPUT LEVEL:
+24dBm into 600 ohm loads. 15Vrms into high
impedance loads.
DISTORTION:
Transformer balanced outputs, .25% maximum THD,
30 to 20,000 Hz, +22dBm. Active balanced outputs,
.05% maximum THD, 20 to 20,000 Hz at +22dBm.
FREQUENCY RESPONSE:
+/-.25dB, 20 to 20,000 Hz -3dB at 3Hz and 40kHz
typical. Square wave rise time, 6µSec, symmetrical.
NOISE:
MMA400/MMA800; E.I.N. = -120dBm maximum with
150 ohm source resistance. MLA400/MLA800; E.I.N. =
-92dBm with 600 ohm source resistance. Both are
measured with 20kHz equivalent square bandwidth. All
hum components are at least 10dB below white noise.
GAIN:
MMA400/MMA800: 64, 74 or 84dB. MLA400/MLA800:
22, 32 or 42dB. Each channel's gain is dependent on
output gain jumper plug position.
CMR:
60dB at 60Hz.
CROSSTALK:
-70dB maximum at 10kHz.
OUTPUTS:
MMA/MLA –1: Transformer Balanced, 60 ohm source
Z. MMA/MLA-2: Active Balanced, 300 ohm source Z,
protected and RF bypassed.
INPUTS:
MMA400/MMA800: Balanced 40dB gain, RF bypassed
Instrumentation Amplifier, Zin = 20Kohm. Maximum
input = -20dBu. Gain can be reduced to 0dB by
removing a jumper to accept line levels up to +22dBu.
MLA400/MLA800: Balanced, -2dB, RF bypassed
Differential Amplifier, Zin = 30Kohm, +22dBm
maximum input.
POWER:
115/230 VAC +/-10%, 47 - 63 Hz, 20VA.
DIMENSIONS & WEIGHT:
19" (48cm) W x 1.75" (4.4cm) H x 7.5" (19 cm) D
10 lbs. (4.5kg)
TERMINALS:
Rear barrier blocks for all input, output and summing
jumpers. Fanning strips with solder terminals provided
for easy prewiring and servicing.
