GENERAL OPERATION

POWER ON/OFF

Press the power button on the front panel or via the IR remote. The blue ring around the power
button will blink for several seconds while the SI-300.2d warms up and initializes. Once the blue
ring steadily glows and you hear a click, the SI-300.2d is ready for use. When powering off, it is
recommended to first turn the volume down to a low level, then press the power button once
again. The SI-300.2d will power on to the same input and volume setting last used. This is why
it is recommended to turn the volume down prior to powering off as to not damage the unit,
speakers, or your hearing.

SPEAKER CONNECTIONS

The SI-300.d is equipped with high quality 5-way speaker binding posts. Simply connect your
speakers positive + and negative – connections to the corresponding positive + and negative –
connectors on the rear of the SI-300.2d. Do not make speaker connections when the unit is
powered on and always start at the speaker end first. We recommend a high quality speaker
cable with high quality spade or banana connectors.

SOURCE CONNECTIONS

Connect all sources to the SI-300.2d with quality RCA or XLR cables for analog sources and
quality USB, coaxial, optical, and AES/EBU cables for digital sources. It is not recommended to
connect or disconnect any source(s) to the SI-300.d while powered on. If your source(s) have a
variable output volume it is typically best to adjust them to 100% output. For sources that have
a very high output (above 2.0 volts) you may want to use the "Mode" button on the IR remote
so that the letter "D" is NOT display next to the volume range on the SI-300.2d front panel. For
sources of less than or equal to 2.0v you may want to experiment with the IR remote "Mode"
function to display the letter "D" next to the volume range.

SWITCHING INPUTS

To switch inputs, simply press the desired input on the SI-300.2d front panel, on the IR remote
control, or via the Android or iOS control apps available for free. When switching inputs, the SI-
300.2d will soft mute the output circuit for a few seconds as a precautionary measure. It is also
recommended to turn the volume down to a reasonable level when switching inputs.

MUTING THE SOUND

You may completely mute the sound of the SI-300.2d either via the front panel display or the IR
remote control. When mute is engaged the word "Mute" will display on the front panel in place
of the volume range. Press the Mute button again or adjust the volume up to disengage mute.
Once disengaged it will take a few seconds for the sound to resume.

VU METERS

A handsome and fun feature of the SI-300.2d are the VU Meters. They show the power output
in wattage into a nominal 8 ohm load. The needles will move in accordance to the amount of
power output. The higher the output the more the needles will move.
Caution: The SI-300.2d is a very powerful amplifier. Please be mindful of this as to not
damage your speakers or your hearing for the sake of watching the meters dance!
