Gain stages, based upon ultra-low noise differential
SHORTEST SIGNAL PATH:
balanced audio amplifiers, are implemented into the shortest signal path of any
previous Rowland preamplifier. All signal paths are balanced from input to output
for maximum noise rejection.
Separate 2nd gain stage for record outputs offers
DUAL-ZONE PREAMPLIFICATION:
same circuitry as the primary signal path with independent volume control.
All inputs and outputs routed through professional
TRANSFORMER-COUPLED:
grade Lundahl transformers for maximum common noise rejection, EMI immunity,
and cross-component compatibility. Transformer coupling also ensures invariant
gain for all balanced inputs and outputs. When used with input transformer
equipped JRDG amplifiers a 140dB dynamic range interface can be achieved. All
unbalanced inputs convert to balanced upon entering the preamp.
6 inputs (4 XLR balanced, 2 RCA unbalanced); 4 main
FLEXIBLE CONNECTIVITY:
outputs (2 XLR balanced, 2 RCA unbalanced); 2 record outputs (1 XLR
balanced, 1 RCA unbalanced); per channel.
Hi resolution independently programmable gain offset on
INPUT GAIN OFFSETS:
each main input ranging from -20dB to +20dB in 0.5dB increments.
High-resolution programmable gain offset on
OUTPUT OFFSET:
MAIN UNBALANCED
(mapped to on the preamplifier back panel) with 0.5dB
OUTPUT 2 OUTPUT B
resolution adjustable relative to (mapped to on the
MAIN OUTPUT 1 OUTPUT A
preamplifier back panel).
Any main input can be configured as unity gain bypass for
UNITY GAIN INPUTS:
compatibility with theater processors.
Independent signal phase inversion control on left and right
PHASE INVERSION:
channels for optimum speaker setup and system checks.
Hi resolution (1.0dB) panning of stereophonic image
CHANNEL BALANCE:
(channel balance) for a maximum +/-20dB shift.
Long life 32x320 pixel custom graphic vacuum fluorescent display (VFD)
VFD:
offers maximum resolution of display data for status indication.
