Initial Setup
Your Sigma 2200i Stereo Integrated Amplifier is delivered with default factory
settings to facilitate initial setup. But we highly recommend that you work with
your Classé dealer for the final setup of the unit. Your dealer’s knowledge and
experience with Classé products will ensure that your audio system is optimized
for your listening space.
However, if you can’t wait to get started, this section is designed to assist you
in setting up and becoming familiar with the Sigma 2200i hardware. Once the
initial setup is complete, be sure to read the rest of this manual to familiarize
yourself with the daily operation and customizable features of your Sigma 2200i.
Step 1
Connect the Sigma 2200i and all system components to AC
power.
Important!
Make sure everything is turned off before connecting power!
Connecting all system components to AC power, before making any
interconnections between components, ensures that every component has a solid
connection to ground. This lessens the chances of a static discharge that may
damage delicate electronics or your loudspeakers.
Step 2
Choose the appropriate cables.
Before you start connecting components together, let’s take a minute to discuss
the cables you will be using. The audio inputs and outputs available on the rear
panel include both balanced XLR connectors and unbalanced, or single-ended,
RCA connectors.
Single-ended RCA audio connections are the most popular means of
transmitting audio in consumer electronics. Because single-ended connections
are susceptible to picking up noise, shorter lengths usually perform best. As long
as you use high quality, low capacitance cables, single-ended connections provide
good results.
However, balanced audio connections between components have the potential
to provide the best analog signal connection because they effectively double the
signal strength. More importantly, as compared to single-ended connections,
they significantly improve resistance to common mode noise, therefore
enhancing audio transparency, detail, and dynamics. To fully realize these
potential benefits, high quality interconnect cables are required.
Please consult your local Classé dealer for advice on which cables are best suited
for your system.
