    Product Description

    Sirius InV proves that a great looking, easy-to-use satellite radio can be affordable Sirius InV is a complete in-vehical solution

    Amazon.com

    One of Sirius’s easiest to use and most affordable receivers, the Sirius InV is a must for satellite radio fans who want a less-expensive entry into the market. Just like other Sirius-compatible receivers, the InV offers a large, easy-to-read display and an intuitive front control panel. But more significantly for people who spend a lot of time in the car, the InV is designed to seamlessly complement your driving routine thanks to the bundled car kit. Note that the InV doesn’t support Sirius’s universal docking architecture–unlike the comparably priced Stratus–so you’ll have to connect it to your stereo console via wires. However, the receiver does offer a complete in-car solution, with a design that’s perfect for smaller vehicles with tight mounting locations. In addition to the receiver, the kit includes a power adapter that connects to your car’s 12- volt cigarette lighter plug, a vehicle antenna for enhanced reception, and a dash mount. Once you’re connected, you’ll have the ability to decode the incoming digital-quality signal from more than 130 music, news, sports, talk, and entertainment channels, many of them commercial-free.

    An intuitive three-line display tells you the channel name and number, artist name, and song title. The receiver also lets you program up to 10 presets of your favorite streams, as well as search by channel name and music category. And with a quick press of the One- Touch Jump button, you can instantly switch between the traffic and weather reports for your city or any of the other music, news, or entertainment channels. Other programming details include direct station tuning via the numeric buttons and a channel lock option.

    The InV also includes a built-in FM transmitter that sends Sirius radio programming to your vehicle’s FM tuner, so you don’t have to make a direct connection to enjoy the full array of channels. Simply set an empty FM frequency on your radio and tune the InV to the same frequency (the transmitter supports up to 100 frequencies). The transmitter also works with other FM tuners, such as the one on your home stereo, but is easily paired with the car thanks to the vehicle kit, which includes everything you need for listening to Sirius while driving.

    Other features include a real-time clock; a parental lock function that restricts your children’s access to off-color material; and compatibility with a separately sold wireless remote control. The InV, which measures 4.5 by 1.9 by 0.7 inches (W x H x D), is backed by a one-year warranty.

    Intelligent Sound – Intelligent Style

    The smooth-edged and rounded design leaves a blue-pearl gloss finish on the fortified aluminum heat-sink. The stream-lined and high-tech appearance will definitely add some attention to your audio.

    Total Audio Control

    Once you are connected, customize and adjust your listening experience to your liking with the amplifier’s control center. You can personalize and fine-tune settings like:

    • High-Pass Filter – When Crossover Mode is in High-Pass Mode, this control limits the frequencies which will be distributed to the speakers Crossover Switch – Routes output of the Low Pass (LP), or the output of the High Pass (HP) filters, or ‘FULL’ to the internal power amplifier.
    • Low-Pass Filter – When Crossover Mode Selector is in Low-Pass Mode, this control limits the frequencies which will be distributed to the speakers.
    • Line Input – Accepts line level (RCA) inputs from 0.2 to 5-Volt.
    • High-in – Accepts speaker level inputs from radios that do not line level (RCA) outputs.
    • Bass EQ – Gives you manual control over Bass Boost decibel adjustments.

    *Please refer to table below for amplifier specific information and adjustment options.

    Input Connections

    Turn the volume control on the amplifier to minimum initially. Once the initial power sequence has been performed, set the volume control to roughly 80% of full power. Play some audio and slowly turn up the amplifier volume control until you hear some distortion, and then back it off for the sharpest sound setting. This amplifier has RCA connections for Low Level inputs. Low Level signal is carried through RCA cables. It is preferred to use Low Level inputs to the amplifier if the headunit is equipped with matching outputs.

    Speaker Output Connections

    Connect right and left speaker wire to corresponding speaker output terminals of the terminals. Be sure to have the positive wire from the speaker to the positive speaker terminal of the amplifier and the negative wire from the speaker must connect with the speaker terminal of the amplifier. Reversing any of these connections will result in the speaker cones moving out of phase which causes bass cancellation.

    Total Audio Control

    Once you’re connected, customize and adjust your listening experience to your liking with the amplifier’s control center. You can personalize and fine-tune settings like:

    • Level (Gain) Control – These are basically volume controls. This will allow you to adjust the incoming signal to the amplifier so that it works well with your headunit or to match the level of other amplifiers in your system.
    • Phase – Allows you to change the relative time that the waveform meets your ear. With standard subwoofer installations where the subwoofer is behind you, the phase should generally be at O. When subwoofers or woofers are in the kick panels or door panels, an adjustment is useful in delaying the timing of the wave meeting your ear.
    • High-Pass Filter – The High Pass crossover is used for sending midrange and high frequency information to a particular speaker. Activate the High Pass crossover if you intend to drive satellite or coaxial speakers in the system along with subwoofers driven by the amplifier’s channels. Even if your system does not include subwoofers, it may be helpful to activate the High Pass with smaller speakers to protect them from low frequency information to achieve better sound.
    • Low-Pass Filter – Filters high frequencies out of the music and improves efficiency and sound quality by allowing only the low frequencies to pass to the subwoofer. Sends only low frequency information to particular speakers. Low Pass crossover activation is usually desired if you intend to power subwoofers.
    • Bass EQ – Variable from a range of decibel adjustments, this feature regulates the impact of your bass kick. You’ll have manual control over balancing and correcting the frequency range of a given sound.
    • Crossover Switch – Basically acts as a filter and limits selected frequencies going to a subwoofer, which gradually reduce frequency signal strength. Routes output of the Low Pass or the output of the High Pass filters, or ‘Full’ to the power amplifier.

    *Please refer to table below for amplifier specific information and adjustment options.

    Speaker Output Connections

    Connect right and left speaker wire to corresponding speaker output terminals. Be sure to correctly connect the selected speaker wires to their respected speaker terminal, this includes both positive and negative wiring. Improper installation/wiring will result in the speaker cones to move out of phase which can cause bass cancellation.

    Input Connections

    These amplifiers have inputs for Low Level input connections. The Low Level signal is carried through RCA connection cables.
