SALES NOTE

Why You Need Summing
Today, more than ever, OEM systems are actively crossing over speaker signals
inside the factory amplifier. They do this because the factory speakers are not
very dynamic and they need to limit the frequencies that are played through each
individual speaker. When aftermarket systems are installed you need the ability to
combine or “sum” multiple crossed over signals back together. The AudioControl LC8i incorporates
a unique internal summing circuit that will allow you to input several different signals and get one
complete, full range, high quality pre-amp signal. There is no need to have multiple adapters. The
AudioControl LC8i is your one box cure for all you OEM Headaches.
Why do AudioControl Line Output Converters work so well?
The LC8i has high-impedance (20K Ohms!!) speaker-level inputs that accept signals from factory in-
stalled amplifiers. Yes, Even Bose. The AudioControl LC8i will work with most factory installed audio
systems and give you high-quality, level matched, pre-amp signal via standard RCA connectors. This
will allow you to add high quality aftermarket amplifiers and processors while keeping the conve-
nience and cosmetic features of the factory installed source unit. Unlike inexpensive passive speaker
level inputs and line output converters, the LC8i gives you the brilliant sound quality like AudioControl
has been providing for over 30 years.
Who is The Customer?
Vehicles with Convenience Features
The convenience features that car manufacturers are integrating into factory-installed head units are cool,
and most new car owners don’t want to give them up. Some of the features available (and sometimes
standard) on new cars are steering wheel controls, navigation, On-star, speed sensitive volume controls, and
satellite radio. The LC8i lets you retain all of these functions and upgrade the sound of the system and add
an iPod or other Aux Input.
European Cars
More and more of today’s high end European automobiles are coming with complex fiber optic and data bus
systems, so the need to have a line output converter that can handle high input impedance has never been
greater. The LC8i allows you to keep the factory signal path intact and, still add high quality aftermarket
amplifiers and speakers to the system.
iPod Owners
Almost everyone has an iPod or a satellite radio. The new LC8i provides a fast and easy portal with an Auxil-
iary input and the included dash remote will switch function from man in to Aux in. The LC8i dash control will
also adjust the volume of the Aux input so your customer won’t have to reach for the iPod. This is especially
useful for satellite radio tuner, which usually have no volume control of their own.
Integrated Dash Panels
Car manufacturers are driven by cost and convenience, not by sound quality. The more functions they can in-
tegrate into one single panel the cheaper the cost. One example is the Ford line that has the passenger side
airbag light inside the radio faceplate. Once removed, there would be no way to tell if the airbag was on or
off and any retailer installing an aftermarket stereo could be liable for injuries sustained by the passengers
who get into an accident.
