FEATURES
(cont'd)
- Discrete
FET,
balanced, symmetrical topology from input to output
- Precision biasing adjusts each
FET for optimal performance, maintains it under varying conditions,
and has shown over decades not to drift
- Extremely high input-output Z ratio
for other applications including summing/buffer amp, phono preamp and headphone amp
Support functions
- Standby mute
function enabled during power-up
sequence, low line and phantom on/off
- Standby
mode reduces power consumption
- Status indicator
shows operational status of
gain control, output stage, standby mute and standby mode
- Shielded internal primary supply
with low
leakage current and extremely low noise
Mechanical
- No steel
– rugged, anodized
aluminum enclosure and stainless steel fastening hardware
- Removable rack kit and optional outriggers
for
freestanding applications
- Gold-plated
contacts and active retention in all internal connectors
- Fully enclosed, gold-plated contacts
in panel switches and relays
- Low-profile buttons and solid aluminum
knob
with two set screws on 6mm metal shaft – no toggle switch
bats, plastic knobs or terminal strips to break
- Protected panel graphics
are printed on the back of clear
panel overlays

BENEFITS
- No color, resulting in extremely high
resolution and tonal purity
- Combines wide dynamic range with wide bandwidth
and both over the entire gain range, not just a sweet spot
- High-compliance input/output
– high performance with a wide variety of
input sources and output loads
- Robust design and build
FEATURES
- Overload-proof
main input
clips
after the output and without pads
- Direct-coupled
output with load compensation
for low distortion output into any load
- Separate gain
control is optional for remote control
- Remote control
eliminates cable losses and
interference by locating the preamplifier near the microphone or
instrument
- Low
noise, high gain
(and
short mic cables with remote) for optimal performance with ribbon
microphones
Signal
path
-
Minimalist signal path is optimized
by extensive support circuitry
-
Balanced,
high-impedance main input,
thru 1/4" and XLR connectors hardwired in parallel, accepts mic, line
or DI sources, plus plug-in input loads
- Auxiliary
input and output options exploit the benefits of the output stage
for use as a second output, line buffer or insert loop
