Imiyalo yokusetshenziswa komkhiqizo
Ukufakwa
The C7-100ct component tweeter can be installed using either
flush or surface mounting fixtures provided with the product.
Ensure a secure and stable installation to prevent any vibrations
or movement that could affect sound quality.
Ukuxhumana
When connecting the tweeter, make sure to include the 15F
protection capacitor in all installations to safeguard against
transient electrical pops during turn-on/off cycles. Note that this
capacitor is not a replacement for high-pass filtering.
Ampukuqinisa
It is recommended to use a dedicated amplifier channel for each
C7 loudspeaker in the system. Choose an amplifier with a power
output within the recommended range of 50-150W (RMS) to ensure
ukusebenza kahle.
Equalization and Tuning
Avoid using passive crossover networks with C7 loudspeakers.
Instead, utilize a high-quality tuning DSP to precisely set up
equalization, delay, and crossover filters. This tuning process
will help achieve the best possible in-vehicle audio
ukusebenza.

I-C7-100ct: 1-intshi (25 mm) Ingxenye ye-Tweeter
ISINGENISO
Siyabonga ngokukhetha izipikha ze-JL Audio C7 zesistimu yakho yomsindo wezimoto. I-C7 iyisiqongo sedizayini yesipikha se-JL Audio, ezuza kubuchwepheshe obunelungelo lobunikazi kanye namathuluzi ethu okuthuthukisa athuthuke kakhulu.
The C7-100ct is a component tweeter designed to deliver unparalleled high-frequency performance. Utilizing a corundum ceramic-coated aluminum alloy diaphragm with a treated silk, s-roll surround, it provides spectacularly detailed reproduction of treble frequencies and outstanding off-axis response. Distortion and non-linearities have been minimized through critical optimization of dynamic motor, diaphragm and suspension behaviors.
Flush and surface mounting fixtures are included to fit a variety of installation applications, as well as a 15F protection capacitor to guard against damage from transient electrical pops (turn-on/off). This capacitor is not a substitute for high-pass filtering, but must be connected in all installations.
Asikuncomi ukusetshenziswa kwamanethiwekhi e-crossover angenamsindo anezipikha ze-C7. Kunalokho, sincoma i-DSP yokushuna yekhwalithi ephezulu kanye nokuzinikela ampisiteshi se-lifier selawudispikha ngasinye se-C7 ohlelweni. Ukusethwa okunembile kokulinganisa, ukubambezeleka kanye nezihlungi ze-crossover kuzoqinisekisa ukusebenza okuphezulu kwemoto.

UKWENZIWA NOBUCHWEPHESHE
I-Dome Diaphragm:
1 Corundum ceramic-coated aluminum alloy diaphragm exhibits high stiffness, very low mass and excellent environmental stability.
Idizayini yokumiswa:
2 The diaphragm’s motion is centered, sprung and dampihlelwe ngosilika olungisiwe, okuzungeza i-s-roll. I-Ferrofluid kugebe kazibuthe isebenza njengesici esingemuva kulo mklamo. Lokhu kokubili kuhlanganisa ukunikeza okungcono kakhulu dampngaphandle kokukhawulela ukuvakasha ngokungafanele.
Idizayini yezimoto:
3 The C7-100ct employs a high-density magnetic circuit with a high-grade, neodymium magnet, and a specially machined, U-Yoke motor topology. An under-hung voice coil is employed, wound with copper-clad aluminum wire onto an aluminum voice coil former. Motor magnetics have been precisely optimized utilizing advanced FEA tools to lower even order distortion and IMD/AMD.
Idizayini ye-Acoustical:
4 The shape of the tweeter housing is designed to boost sensitivity in a very specific bandwidth, helping to flatten the frequency response. It also provides control of directivity.

I-C7-100ct: Ukufakwa
UKUFAKA KWE-TWEETER
Ama-tweeter e-C7 aklanyelwe ukufakwa phezulu noma ukukhweza. Ngaphambi kokukhetha indlela, hlola ngokucophelela indawo yokukhweza oyifunayo ukuze unqume ukuthi iyiphi indlela ezosebenza kangcono.
Surface-Mount: uses the supplied surfacemount fixture and requires the drilling of three holes (two for the wires and one for the mounting screw). This application is useful when mounting the tweeters to a panel that has insufficient clearance behind it for the tweeter’s magnet structure.
Flush-Mount: yields a custom-installed appearance and requires a 1.88-inch (48 mm) diameter hole to be cut in the vehicle panel. At least 1.75-inch (44 mm) of clearance is required behind the tweeter mounting surface for the spring clip and 1-inch machine screw used to mount the fixture. In limited depth applications, it may be necessary to cut down the length of the machine screw, or to use a shorter screw (not supplied). Hand-tighten the machine screw until the fixture is secure, as shown in Diagram C.
I-PROTECTION CAPACITOR
A high-quality 15F protection capacitor is included with the C7-100ct to guard against damage from transient electrical pops (turn-on/off). This capacitor is not a substitute for high-pass filtering and must be connected in all installations. The capacitors value has been selected so as not to interfere with a properly set active high-pass filter.
The protection capacitor supplied with your C7-100ct should be installed in a dry location and as near as possible to the tweeter. Connect the protection capacitor in-line (series) with the tweeter’s positive (+) lead, as shown in Diagram A below. The capacitor is bipolar and may be connected in either direction. Make sure to insulate the capacitor’s leads to guard from touching against any exposed metal. Use plastic cable ties or a similar fastener to securely mount the capacitor to avoid coming loose in the event of a collision, sudden jolt or repeated vibrations during normal use. Make sure that your mounting location will not cause damage to wiring or any other vital component of your vehicle.
TWEETER CONNECTIONS Run the wire leads from the tweeter mounting
locations to the ampimiphumela ye-lifier. Bese uxhuma intambo yamahanisi kusipika/ampimiphumela ye-lifier kanye nama-tweeter, ebona ukuhlukahluka okulungile. Bheka Umdwebo A ngezansi ukuze uthole imininingwane.
!! WA R N I N G
It is absolutely vital that the protection capacitor is connected, as shown in Diagram A. Failure to connect the protection capicitor as shown will result in damage which is NOT covered under warranty.

1) Remove the vehicle panel and check to ensure that the mounting screw will have adequate clearance.
2) Place the surface-mount fixture on the vehicle panel at the desired mounting location and mark the locations of the center mounting screw hole and the approximate center of the left and right semicircular cutouts (for the wires).
3) Using a 1/16-inch (1.5 mm) drill bit, drill a pilot hole through the panel at the center screw location.
4) Using a 1/4-inch (6 mm) drill bit, drill a hole for each of the tweeter’s wires at the locations you marked in step 2.
5) Screw the surface-mount fixture to the vehicle panel using the supplied #8 sheet metal screw (hand-tighten) and #8 flat metal spring nut. Feed a tweeter wire through each semicircular cutout in the mounting fixture and the 1/4-inch holes you drilled in the panel.
6) To attach the tweeter to the fixture, observe the indented locking slots on the outer edge of the tweeter body and align these with the tabs visible on the inside walls of the fixture. Slide the tweeter into the fixture and secure by pressing down on the tweeter and giving it a small clockwise turn.
7) Connect the tweeter’s wires to the wire leads from the ampi-lifier, ibona i-polarity efanele. Faka i-protection capacitor njengoba kushiwo ekhasini lesi-5.
8) Faka kabusha iphaneli yemoto, ngokucophelela ukuhambisa izintambo ezintsha ukuze ungaphazamisi noma yiziphi izindlela zemoto (izindlela zamafasitela, ngokwesibonelo.ample).

1) Khipha iphaneli yemoto futhi uhlole indawo yokukhweza oyifunayo ukuze uqinisekise ukuthi kunemvume eyanele ngemuva kwephaneli yesakhiwo sikazibuthe we-tweeter kanye nehadiwe yokukhweza.
2) Carefully cut a 1.88-inch (48 mm) diameter hole in the vehicle panel. This will achieve a snug fit and allow the tweeter flange to conceal the cut line.
3) Insert the flush-mount fixture from the front of the panel and place the 8-32 machine screw through the center hole of the fixture.
4) From behind the panel, thread the spring clip onto the 8-32 machine screw and hand-tighten until the fixture is secure.
5) Feed a tweeter wire through each semicircular cutout in the fixture from the front of the panel.
6) To attach the tweeter to the fixture, observe the indented locking slots on the outer edge of the tweeter body and align these with the tabs visible on the inside walls of the fixture.
