Six Channel Line Output Converter With Auxiliary Input
For interfacing with factory installed audio systems
G
reetings from the rainforests of the Pacific Northwest. We would
like to congratulate you on your purchase of the LC7, a six-chan-
nel, high-performance, line-output converter with an auxiliary input. This
nifty product will accept two, four, or six channels of speaker-level signal
from a factory-installed amplifier or source unit and convert it to a high-
quality, low-noise pre-amp signal. This makes the LC7 an ideal OEM
(Original Equipment Manufacturer) interface component as it will allow
you to use your factory-installed source unit but give you the ability to
add really good aftermarket amplifier(s) and processor(s). The LC7 also
has an extra set of RCA inputs that allow you to interface your iPod, MP3
player, satellite radio tuner or other audio source. Turntables are not rec-
ommended. Whether this is your first product from the rainforest dwellers
of AudioControl, or you are already a firm believer, you will definitely
enjoy how great the LC7 can make your performance system sound.
Now before you start salivating just thinking about the benefits and
all of the nifty applications for your LC7, take a few minutes to sit back,
grab a beverage of your choice, and read through this manual. It contains
lots of useful facts and information which will probably answer any
questions you may have. If you are one of those folks who "does not like
to read manuals", then you will be happy to know that this manual is
very peppy and has lots of pictures.

This input is activated by tapping the op- tional dash level control. You will be happy to know that the LC7 has an LED indicator that will reflect which input your LC7 is using. - Page 3 For example, in some vehicles there is an actively crossed-over tweeter, midrange, and woofer all in the front of the ve- hicle. The LC7 lets you take all of those signals and sum them together to get a high-quality, full-range, pre-amp signal without the use of any additional cables or hardware.

Page 4: Quick Installation Information
We also recommend that you save your invoice or sales slip as proof of installation and ownership. Not only is it necessary for warranty purpos- es, but should your LC7 “walk away” one day while your car is parked at your local latte’ stand, you will find insurance companies very unforgiv- ing without proof of purchase. - Page 5 If your source unit has front, rear, and subwoofer speaker-level outputs, connect them to the three sets of inputs on your LC7. If the source unit only has front and rear inputs, the Auto Mode circuitry in your LC7 automatically routes the Channel 2 inputs to Channel 3.
- Page 6 12-volt signal. NOTE: If you are using the GTO signal sense on your speaker level inputs, you will probably not need to connect this input. 6. Remote Out: Outputs 12 volts when the LC7 is powered up so you can turn on external devices like signal processors and external amplifi- ers.
- Page 7 10. Pre-Amp Outputs: These RCA connectors should be connected to the next component after the LC7, such as a signal processor, crossover or amplifier. Do not connect any speakers directly to your LC7. (Defi- nitely don’t connect to any home appliances, like your microwave.) 11.
- Page 8 LC7 Block Diagram Installing Your LC7 By this time we are sure that you are chomping at the bit to install your LC7. Up to this point, everything you have read has served to educate you on the operations of LC7. Therefore if you are still with us we recommend you read the following sections very carefully.
- Page 9 Remote connector on the LC7. Remote Out: If you are going to use the LC7 to turn on any external signal processors or amplifiers, connect an 18 to 22 gauge wire from the Remote Out on the LC7 to the remote turn-on of the processors or amplifiers.
- Page 10 LC7 will switch between the main inputs and this auxiliary input. A bright LED indicator on the LC7 chassis will identify which source unit is being used. On this topic, the LC7 provides you with a level control for your auxiliary source which allow you to match the sig- nals between your main source and your auxiliary.
- Page 11 Under the cover are connection jumpers that allow the Main outputs of the LC7 to receive signals from the inputs of Channel pairs 2 and 3. These jumpers allow you to select which input signals will be summed into the Main output.
- Page 12 If your source unit has a subwoofer output (and you are using it), set the out- put level at minimum. 2. Disconnect the RCA cables between your LC7 and the amplifier(s). Oth- erwise get some earplugs. 3. Start playing some dynamic music and set the volume on your source unit to about 3/4 of maximum.

Page 13: Custom Installation
LC7 Turns Off Intermittently: If you are using the GTO signal sensing to turn on your LC7 yet your system is turning off, this may be due to a cel- lular phone interface or navigation system built in to your factory installed source unit. - Page 14 Since the LC7 is a line output converter you may need to turn up the gains on the LC7 or consider adding a pre-amp line driver like the AudioControl Matrix to increase the signal level to your aftermarket amplifiers.

Promises of how well the LC7 will perform are not implied by this warranty. Other than what we have covered in this warranty, we have no obligation, express or implied.
