rendering it immune to jitter. The USB interface is derived from the latest
asynchronous XMOS design which is certified USB 2.0 High Speed and Audio Class
2.0 compliant. Consequently, our mPRE requires a quick driver install for PC
machines and is driverless for Mac (10.6.4 and above) as well as Linux systems.
Incredibly low latency in conjunction with the asynchronous mode communication
and ultra precise clocks permits exceptionally high quality digital streaming. A pre-
amp of this caliber and flexibility will efficiently improve your system.
The mPRE is equipped with a total of 3 analog inputs and outputs. Two of the
analog inputs are RCA and one of them can be configured as a Home Theater
bypass input. The two RCA outputs are the typical variable output type but one of
them can be configured as a fixed out. Finishing it off is the balanced (XLR) input
and output utilizing high quality Neutrik connectors. Due to the extent of this first-
class design, single ended to balanced conversion is inherent in the design and
ensures that all of the independent outputs are active regardless of the selected
input. You can be confident that the signal path for your analog sources are highly
refined with the mPRE.
On the occasion that you are craving a headphone session, the mPRE has a
¼” headphone jack on the front panel so you can plug right into the high
performance headphone amp. Taking advantage of the dual mono design and low
noise, the mPRE is nothing short of impressive. All of the benefits the preamp will
be even more apparent with the headphone stage. An abundance of dynamic range
and power capable of driving headphones down to 16 ohms makes for a true hi
fidelity headphone experience.
Finally, the chassis design is attractive and functional. A front and top view of
the unit reveals only two screws tucked neatly in the rear of the top cover. The
front panel is meticulously machined from a solid piece of ¾” aluminum which is
line grained and anodized in black. A radius on either side of the front panel
smoothly rounds the corners off with elegance. custom side extrusions extend to
the rear of the unit and bare the same high quality anodized finish. The top cover is
available in clear anodize (Silver) or black and has stylish venting allowing heat to
escape. The powder coated steel chassis has additional venting on both the bottom
and rear to help with the passive cooling. You can be sure that the chassis is very
rigid and immune to frequencies and vibrations which can be generated by the
various components in a HiFi system.
