Please note: The Precision
1 is too powerful and it is not for the in-ear headphone.

Audio-gd products had
design and test based on the AP SYS-2722 (The top-drawer
professional equipment in world)
We have over 25
years experience with power amp design and build, we designed the
Precision 1 to enable the whole chassis to work as a heatsink, the chassis
is of pure aluminium, having a 3.7KG weight and a very large heat flow area, improving over standard heatsinks (usually products in this size range have less than 1KG of heatsinks), the
Precision 1 stays at a safer temperature.
Driving the 4 ohm
Moby-Dick speaker, the Precision 1 reproduces detailed and dynamic sound.
characteristic I / V conversion mode volume control design
, has a very wide volume control characteristic, cooperating
with both speakers and headphones.
Selecting the volume mode from low to high, the volume will reset to 0 avoiding accidental high output.
Non- feedback ACSS analog amps.
The gain stages and pre-driver stages working in
class A, built with discrete analog stages without any OPA
and coupling caps in the signal channels.
The Diamond Cross Non-feedback output stages design can avoid "switch
distortion", rivaling class A amps.
Full functions (DC offset and overload) MCU protection detect
for protecting speakers and the amp.
Separate two channel
80 steps digitally controlled relay-based volume
control avoids channel imbalance, channel cross and improves sound quality .
High / Low volume model, easily handles varied sensitivity
headphones and speakers.
4 analog inputs:
RCA X3, ACSS X1
Applies 8 transistors ( 150W / 15A / pc). Supports 90W
X2 (8 Ohms) output or 16W X2 (40 Ohms).
The capacitance of the whole machine reaches as high as 45,000 uF,
A total of 2 groups of high-quality class A parallel connection
PSU power supplies for the gain stages. To achieve high S/N, the
control circuit is powered with separate regulators.
Applies all audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER
(UK brand) caps.

Very neutral, truly delivering the sound of source, the Precision 1 doesn't add
any color. Precision 1 is not a monster amp but can driver most speakers
well. It benefits from high quality sources, speakers
and cables to show it's true performance .
Please note: Before operating the Precision 1, it is suggested that you
read the User Manual page.
