Integration of High-performance and Ergonomic Design,
USB DAC/Headphone Amplifier supporting DSD 5.6 and PCM 24/192
Ergonomic and human-friendly design
From the human-engineering point of view, the design of the
HA-P5 started from the scratch. Compactness, lightweight and comfortable for
human hands are keys to design, and it weighs only 182g or 6.4 oz. which is the
lightest among TEAC’s portable headphone amplifiers.
Delivering the finest sound on the street, as a piece of
The fundamental circuit design of the HA-P5 is based on the
highly reputed TEAC Reference 501 series, the UD-501, a USB DAC, and the
HA-501, a Headphone Amplifier. A high-performance D/A Converter PCM1795 from
Burr-Brown allows the Hi-Res digital data to maximize its potential, as
discrete designed push-pull circuit delivers high-quality audio signal from its
1/8" headphone jack.
Made in Tokyo
High-quality is another answer from TEAC. Every single HA-P5
is manufactured at the TEAC's own factory in Tokyo, Japan, all through the assembly
processes, from the soldering to the final quality checking and the packing.
Performance – High-performance digital circuit that
pioneering the Hi-Res Audio Era
Burr-Brown PCM1795 D/A Converter
Same as the highly reputed USB DAC, the TEAC UD-501, and an
industry-standard DSD Master Recorder, the TASCAM DA-3000 for recording studios
and broadcasting stations, a high-performance D/A Converter, Burr-Brown PCM1795
settles in the heart of digital section to process millions of calculations a
second that Hi-Res audio data require.
Dual on-board master clocks for 44.1kHz and 48kHz systems
Master clock is another key player on digital processing.
The HA-P5 employs two high-precision crystal master clocks for 44.1kH
(22.5792MHz) and 48kHz (24.576MHz) systems, to be synchronized with sampling
frequency of the incoming digital audio signal precisely, which means an
accurate Digital-to-Analog conversion is processed. Asynchronous transfer mode
is also supported to cancel less-accurate clock signal sent from a computer or smartphone,
– that affects to digital audio data while traveling – known as jitter-noise.
Circuit design eliminating noise interference
Circuit layout is designed to separate digital and analog
sections, in order to eliminate distortions that is produced by interference
The HA-P5 supports both USB A and USB Micro B inputs for
direct connection with iOS devices – meaning no additional cable is required,
such as Apple's Lightning-USB Camera Adapter –, allowing DSD 5.6MHz and PCM
24-bit/192kHz Hi-Res Audio input. They also allow connections with Android
device, and Windows/Macintosh computers as well, at DSD 5.6MHz and PCM
24-bit/192kHz. A Hi-Res Audio Player software/app is provided free of charge.
Years of experiences
from Headphone Amplifier Design
Discrete design with Push-pull circuit and Hi-Fi Op-amps
An A/B class headphone amplifier design is discretely
composed with Push-pull circuit and Hi-Fi Op-amps. Know-hows from the world's
reference headphone amplifier HA-501 are stuffed into the HA-P5, and its
noise-reduced and crystal clear circuit design delivers 10 to 100,000Hz of
frequency response and 110dB of Signal-to-Noise ratio, that mean the HA-P5
delivers both details of the master tape quality brought by Hi-Res audio format
and nuances of the atmosphere as they were originally played.
Low-distortion and high-precision Op-amps OPA 1602 from
Audio Op-amps Burr-Brown OPA1602 SoundPLUS® are employed in
the headphone amplifier section, for low-distortion sound.
160mW + 160mW High-performance Power Amplifier
Thanks to its high-voltage and low-impedance circuit design,
the HA-P5 delivers 160mW + 160mW of output power at 32-ohms load, or 30mW +
30mW at 600-ohms load, which are incomparable performance in Portable Headphone
High-quality Chip-film Capacitors designed for Hi-Fi
Large capacity chip-film capacitors are employed to
eliminate its by-product noise and unnecessary vibrations.
Left and Right channel separated-ground circuit
From the headphone amplifier section to the 4-pole headphone
jack, each ground of the left and right channel is completely separated from
another, as conventional portable audio device share the same ground that
causes worth channel-separation. The HA-P5's separated-grounds are also
independent from that of amplifier section, and it contributes to deliver clear
and "visible" sound stage.
The 4-pole headphone jack is also compatible with a
conventional 3-pole headphone jack.
Pin assignment of the pole is as follows*. (from tip to bottom)
* Same as the Sony NW-ZX2 and Oppo HA-2.
Digital and Analog Inputs
In addition to the USB digital audio input, the HA-P5 equips
both coaxial and optical digital audio inputs and a conventional analog line
audio input, which are essential for portable headphone amplifiers. The coaxial
and optical digital inputs supporting 24-bit/192kHz allows you to connect with
a Hi-Res Audio player to compare differences of the sound generated by
different D/A converter chip.
Multi-platform configuration and free Hi-Res playback
Complementary Hi-Res audio playback apps/softwares are
supplied from TEAC for both iOS and Android devices and both Windows and
Macintosh computers. You will enjoy profound sound world of DSD 5.6MHz native
Hi-Res sound on any platform you own.
Conventional Analog Audio output
Another advantage of the HA-P5 is a conventional analog
audio output that is independent from the headphone amplifier section. This
allows you to connect your existing home hi-fi system as a DAC unit, and turns
it into today's Hi-Res hi-fi system.
Ergonomic design that
merges functionality and beauty
Volume knob design that prevent from unwanted operations
The volume knob is seamlessly designed with the top-end
shape to prevent from unwanted operations in your pocket or bag. Embowed curve
of the knob comfortably fits your finger as you operate, and is also allows
Simplified LED indicators
Status indicators that tell sampling rate of the incoming
digital audio and battery indicator are carefully and elegantly located on the
These allow you to confirm type of signal that is actually being played back at
a glance. Battery level is displayed in 5 steps, and the blue LED around the
volume knob blinks when it is low.
Light-weight body for mobile use
The HA-P5 employs full aluminum body not only for
light-weight and robustness, but also for noise shielding.
Universal USB charging
A built-in Li-ion rechargeable battery allows 5 hours of
operation (at digital connection), and it is compatible with de-fact standard
USB AC adapters that supply 1.0A or more DC power.
Made at the TEAC's
own factory in Tokyo, Japan
High-quality Print Circuit Boards
Any fine audio components and circuit design will not work
well unless they are firmly mounted on a high-quality circuit board. The HA-P5's
circuit boards are manufactured in a specialized factory in Japan, who produces
that for professional audio equipment for broadcasting/recording industries. A
thick-membrane copper layer with even thickness is employed for lowering
impedance of the entire circuits, and its evenness contributes to equalize
current level on the both power and ground lines, consequently, it refines
Soldering process is operated in the soldering pool filled
with nitrogen that eliminates oxidization during the process, and improves
reliability of the soldering. Also, material of the soldering is carefully
selected for finer sound quality by improving current flow.
