BUFFERED VOLUME CONTROL
The STEELHEAD is equipped to drive external power amplifiers directly via low output
impedance VARIable line drivers. Purists may easily bypass other outboard preamplifier circuitry
by connecting power amplifier inputs directly to the STEELHEAD’s VARIable output jacks.
8.
SEPARATE BUFFERED FIXED AND VARIABLE OUTPUTS
Choice of constant-level source for interconnection to a line-level-only preamp or recorder,
and variable outputs for direct connection to power amplifiers.
9.
DISCRETE CIRCUIT AND CHASSIS GROUND POINTS
Breakable link between electronics common “zero volts” point and chassis ground allows
great flexibility in grounding arrangements.
10.
REMOTE HIGH PERFORMANCE POWER SUPPLY
Multiple channel power supply in separate enclosure eliminates supply proximity-based noise
intrusions into the signal path. Robust and regulated ultra quiet high-voltage rail maintains
electrical quiet for sensitive gain input stages. Each voltage channel is conveyed to the preamplifier
via separate source and sink lines; no common supply points except at the star-grounding point on
the amplifier boards. Multi-core interconnect cable is screened via tinned overall shield braid.
