How to install the
TE8802 driver?
Fully balanced design built by discrete analog stages without any OPA and couple caps in the signal channels.
Non- feedback ACSS analog output stage .
Uses three R-core transformers (135W total) separate power supplys
for the digital part , right channel and left channel.
More than 50,000uf audio grade NOVER capacitors are used to ensure
ample and smooth power feed.
A total of 11 class A PSU groups are used to purify the power
supply. To achieve high S/N, the control circuit is powered with
separate regulator.
Uses most Hi-end grade parts and exact match transistors.
Four-channel digitally controlled relay-based volume control to
avoid channel imbalance and improve sound quality. NFB-20.2 has 99
steps volume level control in both high gain mode and low gain mode.
5 groups digital input :
AES / BNC+RCA coaxial / RCA coaxial / Optical / USB
3 groups analog preamp input :
XLR / RCA / RCA
Preamp / DAC output :
XLR / RCA / ACSS (variable)
Headphone output :
4 pins XLR / 6.3MM SE
USB Audio Class 2 High-speed Input from PC/MAC
Supports full speed Asynchronous Transfer Mode
Resolutions support 16 / 24-Bit with sampling rate support 44.1kHz,
48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz ( USB model)
Supports up to 24Bit/192KHz (coaxial & AES )
Supports 2X , 4X and 8X oversampling customers setting
Memorizes all settings and it could resume the last settings when
power on.
Sound Characteristics:
"Neutral but smoothness sounding ,it
doesn't sound skeletal or digital (or metallic). There's meat aplenty on
them bones . It's a sigma-delta DAC chip implementation without the
dryness, neutrality without the emotional disconnection" - John Darko
If only the RCA or 6.3MM headphone is used, is the NFB-20.2
being wasted or not fully utilized?
NFB-20.2 is
a real balanced DAC built in headphone amp . It has balanced output
(ACSS, XLR and balanced headphone output) and single-ended output
. There are 4 ACSS amplifiers in the NFB-20.2 for balanced outputs and balanced inputs. Even when a
single-ended output is used, the ¡§Dual WM8741¡¨ DA chips will perform
fully thanks to the fully balanced design.
Note:
NFB-20.2 have 3 feet
under bottom side for the best balance state , if customers want 4
feet , please ask the custom order .
