SPECIAL DESIGN FEATURES

Balanced integrated ampli er design housed inside a low pro le,
COMPACT ELEGANCE:
compact, ultra-low resonance, structurally rigid chassis that is precision-machined
from solid blocks of aircraft grade 6061-T6 aluminum that is completely sealed for
trouble-free operation and high RF and EMI isolation. An auto-ranging switch-mode
power supply accepts all world-wide mains voltages. The elegant front panel is
precision-machined and sculpted with a diamond tipped cutting tool.
Dual low impedance line-level outputs (80 ohms balanced, 40 ohms
I/O FLEXIBILITY:
unbalanced), 40k ohms balanced and unbalanced inputs, and preamp bypass inputs
allow unprecedented compatibility with audio and A/V components.
Extensive use of Lead (Pb)-free, low
HIGH-PRECISION SURFACE MOUNT COMPONENTS:
temperature coefficient, active and passive surface-mount components results in
signi cantly smaller loop areas, reduced circuit capacitance and inductance, and
introduces less noise than conventional leaded components.
THIN-FILM RESISTORS: All resistors are low noise, 0.1% thin- lm type for extremely low
thermal noise which complement the low-noise characteristics of the active circuitry.
FOUR-LAYER CIRCUIT BOARD: All circuitry is populated on one side of a 4 layer circuit
board to allow for continuous, unbroken, low impedance ground and power supply
distribution planes. Care was taken to minimize signal path lengths and components
sizes.
Transformer coupled input circuitry provides
TRANSFORMER-COUPLING AND ISOLATION:
universal component compatibility and virtually eliminates ground loop noise and RFI/
EMI. Transformer coupling ensures identical overall gain when using unbalanced input
adapters. Other bene ts include ground noise isolation and excellent common mode
noise rejection (CMRR) from all sources.
Dual rate volume control allows precision level
PRECISION VOLUME ADJUSTMENTS:
adjustments over nearly a 100 dB range. The volume control incorporates a
permanently noiseless optical encoder that always maintain its tactile feel, accuracy,
and channel balance at all settings. The optical encoder mounted behind the volume
knob commands the attenuation level of a monolithic resistor attenuator over a 99.5
dB range in 0.5 dB increments. Excellent channel matching, monotonicity, and low
noise is achieved throughout the entire volume adjustment range over the lifetime of
the product.
