Initial Setup

Your Delta PRE Stereo Preamp/Processor 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 preamp/processor. 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 Delta PRE 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 Delta PRE.
Step 1
Connect the Delta PRE and all system components to AC power.
Make sure everything–especially your power amplifier(s)–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 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. As long as you use high quality, low
capacitance cables, single-ended connections provide very satisfactory results.
However, balanced audio connections between components 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.
Step 3
Connect source components to the Delta PRE rear panel.
If necessary, refer to the Rear Panel section in this manual for a detailed
description of each connector found on the rear panel. Your local Classé dealer
