Introduction

Thank you for purchasing the Wyred 4 Sound mINT. This compact integrated
amplifier is a very versatile unit that will fit well in many systems for years to come.
Extensive amounts of time and engineering have been applied to produce
remarkable performance and a noteworthy feature set in a chassis smaller than the
average DAC.

The transparent nature of a Wyred 4 Sound product is able to reproduce your
favorite recording with an abundance of detail and clarity. The internal circuits and
components are carefully selected and designed to reproduce this W4S sonic
signature. Nothing is better than having colorless power behind your music!

We understand that there are many other products on the market which have
similar features and internal parts. It is important to understand that it is what you
do with those parts and the circuits around them to define the products
performance, sonics and uniqueness. We design and manufacture our products in

the USA yet still offer value comparable to those produced in regions where
manufacturing is much less costly. Aside from great sonic performance, build quality
and customer service are on the top of our priority list.

Design and Feature Overview

The mINT chassis was designed around the internal components. Its physical
size could not have been any smaller! In the brainstorming stage of this project EJ
Sarmento set out to create a unit that pushed the envelope in terms of size,
performance, features, and value. At times when the feature set was discussed we
couldn’t help but laugh about the versatility that this sleek box would provide with a
footprint slightly larger than a DVD case. After all, our economy is not as strong as it
was ten years ago and an affordable, small integrated amp with a built in DAC and
head phone amp just makes sense.

There are many reasons why this mini integrated amplifier is unique. To start
with, the volume control in the mINT is a true-resistive ladder which results in linear
control, excellent channel matching, and impressive sonic quality. It was no simple
task to attain these qualities using the one-turn analog pot on the mINT, so it was
necessary to step outside of the box. Rather than passing the signal through the pot,
it is only used as a position reference. A soft ramp feature means that when
powering the unit on/off or using the mute/un-mute it increases/decreases the
volume at a pleasant rate. The mINT has a 12V DC trigger in and out as well as an
external mains voltage switch.

Two analog inputs (Auxiliary 1 and 2) are side by side on the rear panel. An
alternate function of Aux 2 is HT bypass (Home Theater bypass) and is activated via a
push switch on the back. When HT is selected, the trigger in becomes one activation
point for the HT mode. Aux Out (preamp output) will work very well to incorporate a
powered subwoofer. In addition to the pre-out the mINT has a Fixed out that will
typically be used to send a signal to a recording device or feed a signal to a second
system. An alternate function of the Fixed out is a Main In feature that can be used
with the preamp output to allow the insertion of a digital crossover or processor into
the signal path. This feature can be selected by the “Fixed out/Main in” button
located on the rear of the unit next to the HT Bypass selector.

Located top and center of the rear panel, you will find three digital inputs
powered by an ESS DAC chip for an incredible experience when streaming your
digital recordings. The S/PDIF inputs will support 24 bit 192kHz resolution files and
the USB interface will support 24 bit 96kHz signals in asynchronous input. Each
digital input can be connected to a different source and selected independently via
the remote or input select buttons on the front.

A ¼” headphone jack is machined into the left had side of the front panel.
When a headphone plug is inserted into the jack it will mute the other outputs
(other than the Fixed outputs) regardless of the input selected or volume level. The
performance of the built-in headphone amp is nothing short of impressive.
Independent power supplies for exceptionally low channel crosstalk, low noise and
an abundance of dynamic range make for true hi fidelity headphone experience.

Did you think we were done, Ha!, now the most important part! The final
area of focus is the source of on-board amplification, after all it is an integrated
amplifier! Utilizing two independent ICEpower™ modules, the mINT is capable of
outputting 100wpc into 8 ohms and 170wpc into 4 ohms. As a result it will drive the
majority of speakers on the market with ease.

AC Mains Voltage switch

Located on the left side of the rear panel is a Input mains Voltage switch.
When changing the 2 position slider switch the mINT will need to be unplugged and
powered down for at least 2 minutes. It is very important to ensure that the slide

switch is in the proper position which is down for 115V and up for 230V. Failure to
do so will likely result in damaging the internal components and will not be
covered under warranty.

Getting connected

CAUTION: Disconnect the power cord or put the power switch in the “off” position
before making any connections to your integrated amplifier to minimize the risk of
electric shock and possible loudspeaker damage. Power your mINT “on” after all
final connections have been made.

Each binding post is made of highly ductile “OFC” copper alloy. Both clamping
nuts are built out of one piece, and offers excellent grip. All metallic surfaces offer a
24-carat gold-plating, and are non magnetic surfaces. The binding post will accept
4mm banana plugs, spades of 6 and 8mm, and crimped cable ends up to 10 AWG.
The easiest connection is made with banana plugs, but be sure that you use the
highest quality that you can find. Make sure that the banana plugs fit snugly into the
terminals. Some inexpensive banana plugs can cause a highly resistive connection
which can result in a noticeably higher distortion output to the connected speakers.
