MONT BLANC-E12

A MASTERPIECE

WELCOMED BY THE ENTIRE WORLD

Portable Headphone Amplifier

Distortion to
the Minimum of 0.000015%

PROFESSIONAL
OPERATIONAL AMPLIFIER
WITH HIGH FIDELITY

Top-of-the-line
Opamp pairing:

Mont Blanc adopts the high-performance Opamp combination
OPA1611 and LME49600, which was specially designed for
Hi-Fi audio products by Texas Instruments of USA.
Of the two, OPA1611 serves as the voltage amplifier,
while LME49600 is responsible for supplying current to the
output. The two top-flight opamps each working as designed
can achieve near-zero distortion at 0.000015%.
Note:0.000015% refers only to the original technical data of the OPAMP itself,
not the performance of Mont Blanc as a whole.

TRIED AND TESTED
CIRCUIT FRAMEWORK
GUARANTEED SOUND
FIDELITY

We continue to employ the mature, tried and tested
opamp + buffer design in the E12 circuit,
thus striking the best balance between sonic performance,
longevity and reliability. Top quality components, such as
genuine WIMA capacitors and Alps potentiometers,
are carefully chosen and matched to maximize system performance.
High frequency, low resistance output coupling capacitors are chosen,
yielding minimal distortion and output impedance.
The attention to detail and sound tuning on the Mont Blanc
is comparable to that on a Steinway piano.

INNOVATIVE
POWER DESIGN
22V High-Voltage Power Supply


Mont Blanc is powered by an ultra-high-capacity
Li-polymer battery rated for 9000mWh. It consists

of 3 3.7V cells in series to supply a +11V rail.
High-performancevoltage conversion circuitry
further providesa -11V rail. The 22V high-voltage
power supply ensures that the full potential of the
high quality OPA1611 is unleashed, and provides
enough voltage swing to drive even high-impedance
headphones to full dynamic peaks. Mont Blanc
is rated for a maximum output power of 850mW.

USB
SMART
RECHARGING

The Quickest and Most Convenient
of its Kind

Generally speaking, Mont Blanc’s battery, with 3 cells in series
reaching 11V end-to-end voltage, requires a non-standard 14V
adapter for charging.

But to bring convenience to all end-users,
we instead added a DC-DC voltage converter
to boost the 5V USB voltage to 14V to recharge the
3-cell battery. Therefore, users are free to charge
it from computer USB ports or the many power adapters
and mobile chargers available for charging mobile phones.

Moreover, Mont Blanc’s charging circuitry intelligently
adapts to the different currents available from computer
USB ports and other standalone chargers, thus getting the
battery recharged in the shortest time.

So users can charge from any 5V power source available,
but at the same time get it charged most quickly using
high-power adapters. Using a power adapter capable of
2A current output (such as those used forcharging tablet PCs), Mont Blanc charges from empty to full in just 3 hours.

USER-
FRIENDLY
AND FUNCTIONAL

Mont Blanc has added a user-friendly charging indicator
light. Quick blinking indicates fast charging; slow blinking
indicates slow charging. This lets users understand the
amp’s working status easily.

Moreover, to adapt to headphones of different impedance,
frequency response and sensitivities, Mont Blanc comes
with a gain switch and a bass boost function. Users can
enable these functions according to their needs and
preferences. Furthermore, a crossfeed function has been
added to simulate loudspeaker sound field and reduce
the in-head soundstage effect of headphones.
Safe amplification: to prevent on/off transients,
and to protect the amp and headphones under abnormal
conditions, the output is DC decoupled and a breaker trips
on an internal fault. After the circuit fault is remedied,
switching off and on the unit again resets the breaker and
restores the unit to working order.

Minimalist Metal Fashion
SUPER SLIM
BRUSHED ALUMINIUM

CASE

Housed in a seamless all-aluminium outer shell,
Mont Blanc also boasts strong internal supports,
so the appearance of sturdy construction is more than skin-deep.
Two concealed screws on the tail end of the case allow easy access to
the internals of the amp while keeping the shell clean and streamlined.
Through careful circuit routing miniaturization and the use of a monocoque chassis,
we succeeded in thinning down this high-power amplifier to 14.5mm.
Exquisite wire-brushed metal finish is applied to the surface, and concentric
microgrooves on the face of the volume knob catch the light attractively while the
barrel is knurled to give an utilitarian look and a secure grip.
The workmanship and attention to detail on the Mont Blanc marks a big leap forward
in industrial design for FiiO.
