Associated Components - Infinity ERS 840 Installation Manual

Adjusting ERS Series Speakers
1. If you purchased an ERS 840 or 640, you will need to adjust the
built-in tweeter level control (if not, skip to Step 2). Start with each
control at the 12:00 position, and listen to a wide variety of program
material. Adjust each control until you hear the high frequencies
blend well with the upper midrange frequencies. Generally, once
set, each control should remain at the chosen settings unless there
is a significant change in the room environment.
2. When finished, gently insert the grilles into the slots on the
speaker frames. Place an Infinity Logo (self-adhesive) on each
grille (see Figure 4 on page 6). For the ERS 360, place the logo
along the grille's circular edge.
NOTE: Rooms with heavy drapes, thick carpets and heavily-padded
furniture will require more output from the tweeters than rooms with
a wide expanse of glass or mirrors, hard floors, or smooth furniture.

Associated Components

The choice of associated components in your system is critical and
should be made with great care. Here are several suggestions:
• Use a high-powered amplifier (see page 9 for minimum/maximum
power ratings for ERS models). Higher power results in not only
cleaner, more open sound, but insures that the speaker will not be
harmed by an overdriven system that is generating distortion.
• Never operate your system with the bass, treble and loudness
controls set to full boost. This will place undue strain on the
speakers, as well as the amplifier.
• Always turn down the volume control when changing a CD,
record or tape, or switching to AM or FM operation.
Excessively loud transients (clicks or popping sounds) can
damage the speakers.
• Whenever changing cables, pulling plugs, etc., always turn off
all equipment to prevent transients from entering the
speakers. It is always worthwhile discussing proper speaker
connection and component selection with your dealer prior to
setting up your system.
