Features of This Unit
4 parallel push-pull output stages
4-parallel push-pull amplification circuit structured with
3-stage Darlington.
Rated output of 120 W+120 W (8Ω), 210 W+210 W (4Ω).
ODNF
- Only Distortion Negative Feedback -
The amplification feedback circuit that has acquired the high-
speed primary slew rate and ultra-wide bandwidth by feeding
back only distortion components generated during amplifica-
tion for the main amplifier to maintain the pure sound quality
that is almost non-feedback.
With ODNF’s latest version 4.0, in the amplification circuit,
the first stage is 4-parallelized and the second stage is con-
nected with Darlington. Due to these improvements, the low
impedance and high S/N ratio of the transmission circuit have
become possible.
In addition, the input stage of the error detection circuit is
3-parallelized to improve distortion and noise.
BTL connection mode
The BTL connection mode with use of 2 units of this product
has achieved a high-quality and high-power monaural ampli-
fier structure.
2-channel input selector
Switching between unbalanced input of RCA terminal sup-
porting large plugs and balanced input of XLR terminal manu-
factured by Neutrik that supports high-grade balanced signal
transmission is possible.
Balanced input phase selection
Balanced input phase selection switch is equipped, which is
useful for the case of connecting foreign-made input devices.
Selector relay
Selector relay with high sound quality used in Luxman ampli-
fiers enhances the separation and crosstalk performances.
High-inertia power supply
L and R separated high-inertia power supply circuit combin-
ing a large-capacity EI-core-type power transformer with cus-
tomizable 10,000μF × 8 block capacitors are used.
