SoundImpress HY1200 Stereo Amplier
1200WPC | Ncore® | Powered by Hypex
The HY1200-2CH is a compact, high
performance, two channel and no-nonsense
class-D power amplier. It incorporates the
proven and renown Hypex Ncore® technology
for nothing less than impressive performance!
The performance stands out with authoritative
and tightly controlled low registers, high
dynamics and crystal clear mid- and high-
frequencies. The super-low noise level generates
a completely black background to reveal the
tiniest of details in every recording.
All SoundImpress ampliers are hand assembled
in the Netherlands. The custom milled aluminum
enclosure houses the Hypex NC1200 amplier
module, the best thermal material for audio
devices. The in- and output connections are
provided through high-quality binding posts
from CMC and XLR-chassis from Neutrik and
wiring from Mogami and Belden. It can operate
from both 110 and 230 VAC mains voltage
due to it's universal mains input compatibility
featuring an automatic input voltage doubler. 

INTRODUCTION
Small and powerfull
This amplier can deliver all its power from as
low as 2 ohm impedance combined with low
idle loss, very low distortion and noise levels.
Chief distinguishing features are at frequency
response irrespective of load impedance, nearly
frequency independent distortion behaviour
and very low radiated and conducted EMI.
This results in performances such as the max
output power of 1200 Wrms at 2 ohm per
channel, a Signal-to-Noise Ratio (SNR) of 128
dB and astonishing distorting level of 0.004%.
An amplier is only as good as the power supply
it contains. In this SoundImpress amplier,
the power supply and amplier are located on
one board. The switched-mode power supply
(SMPS) providing the power for the amplier is a
compact, high power, highly efcient, regulated
half bridge converter with synchronous
rectication on the main output rails. These
properties make this technology ideal for
powering Class D audio ampliers.
