INTRODUCTION
Sound Impress HY502-2CH
Sound Impress HY502 Stereo Amplifier 500WPC | Ncore® | Powered by Hypex
The HY502-2CH is a compact, high performance, two channel and no-nonsense
class-D power amplifier. 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 highfrequencies. The
super-low noise level generates a completely black background to reveal the
tiniest of details in every recording.
All Sound Impress amplifiers are hand assembled in the Netherlands. The custom
milled aluminum enclosure houses the Hypex NC502MP amplifier 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.
Small and powerful
This amplifier 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 flat frequency response irrespective of load
impedance, nearly frequency independent distortion behaviour and very low
radiated and conducted EMI. Tthis results in performances such as the max
output power of 500 Wrms at 4 ohm per channel, a Signal-to-Noise Ratio (SNR)
of 124 dB and astonishing distorting level of 0.0018%.
An amplifier is only as good as the power supply it contains. In this Sound Impress amplifier, the power supply and amplifier are located on one board. The switched-mode power supply (SMPS) providing the power for the amplifier is a compact, high power, highly efficient, regulated half bridge converter with synchronous rectification on the main output rails. These properties make this technology ideal for powering Class D audio amplifiers.

GET STARTED
START – Before turning on your new amplifier, first make all connections.
Ensure that the volume on your pre-amplifier or playback device is set to a
minimum.
CONNECTION – The HY502-2CH has two sets of speaker connections which are
identical in function (parallel connection). Connect the Right speaker
terminals marked “R +” and “R-” to the corresponding “+” and “-“ terminals of
your designated right speaker. Repeat the same for Left speaker terminals and
corresponding left speaker.
This amplifier will work with both balanced and unbalanced inputs.
For single-ended sources you can use a RCA to XLR cable or converter plug. The
cable or converter should short signal ground (XLR pin 1) with negative signal
input (XLR pin 3).
PLAY – Turn on the amplifier. Slowly increase the volume while playing
some music.
ENJOY!
