Specifications |
|
|
Gain: |
(s/n 0503_ or greater), Mic Input to
Output, per channel, continuously variable
Output: Line, Gain Range: off-66db
Output: Line, Gain Range: off-56db |
|
Equivalent Input Noise: |
-126 dBu (-128 dBV) maximum (150 ohm
source, flat weighting, 22 - 22 kHz bandwidth, gain control set at 50% or
higher, phantom power off) |
|
Output Clipping Level (Line): |
+22 dBu minimum with 100k ohm load, +20 dBu
minimum with 600 ohm load |
|
Dynamic Range: |
110 dB minimum |
|
THD + Noise: |
0.05% maximum (from 60 Hz to 22 kHz @ +4
dBu output level, 22 Hz - 22 kHz filter bandwidth, gain control at 50%,
phantom off) |
|
Inputs: |
Transformer-balanced, 2k ohm input
impedance |
|
Outputs (XLR): |
s/n < 0507 - impedance-balanced, 120 ohm
output impedance,
s/n >0507 - active-balanced, 120 ohm output impedance |
|
Outputs (Tape): |
Unbalanced, tip-left, ring-right,
sleeve-ground, 2.4k ohm output impedance |
|
Power (Internal): |
2 AA alkaline batteries, 6 hours life
typical with +4 dBu signal into 600 ohms, no phantom power |
|
Power (External): |
5 - 18 VDC via 4-pin Hirose connector
(pin-4 positive, pin-1 negative), voltages above 14 VDC cause no damage to
unit, but will open an internal poly fuse. Poly fuse will reset when
voltage is removed |
|
Power LED: |
Green indicates power and good battery. Red
indicates power and low battery. LED turns red when approximately 1 hour
of battery life remain (with phantom power off). Green with external DC
power |
|
Frequency Response: |
20 Hz - 30 kHz, +0.1, -0.5 dB; -1 dB at 5
Hz & 50 kHz (relative to 1 kHz with 150 ohm source, gain controls set at
50%) |
|
Input Clipping Level: |
-10 dBu minimum |
|

100 dB minimum at 80 Hz, 60 dB minimum at
10 kHz |
|
Channel Separation: |
Greater than 80 dB at 1 kHz (gain controls
set to 50%) |
|
High-Pass Filters: |
80 Hz or 160 Hz (switch selectable), 6 dB
per octave |
|
Phantom Power: |
48 V through 6.8k resistors or 15 V through
680 ohm resistors (switch selectable) |
|

Thresholds adjustable per channel from -10
dBu to +18 dBu, 10:1 limiting ratio, 5 mS attack time, 100 mS release
time, Amber/Red LED indicates limiting/clipping, Dual mono or stereo
linked |
