Simply put, a cable amplifier is a box that boosts your antenna or cable TV signals. When your cable signal comes into the house, it is generally strong enough to provide a good signal to two or three televisions. However most homes have many more than three TVs - and that doesn't even include all of the TV accessories! Cable TV boxes, VCRs, TiVo, ReplayTV - all of these boxes require a good strong signal to provide you with a good picture.

You will need a standard usb cable (the one that is included in the box when you buy the phone). Because you are going to use a usb cable you have to install drivers for this cable. You can find this drivers at the downloads page If you do not have this cable you can buy it from us. For now go to contact site to ask us for the cable. You can also buy it in every electronic store and ebay. It's often the same cable as used to connect digital (video) camera's to a pc. See similar questions...

The problem is that most people tend to oversimplify the problem of weak signal reception and how it can best be solved. While adding a preamplifier will boost weak signals so that they can be heard easier, this device also boosts ambient noise as well as already strong signals. The biggest problem here is that by increasing the strength of already strong signals, you are bombarding your receiver with a large amount of radio frequency energy it might not be able to handle.

Generally, NO. There are specific circumstances where you may need to purchase multiple amplifiers. Most homes do not need more than one amplifier to fix cable reception problems. In the rare situation where you think you may need more than one amplifier, please ask for help before purchasing. In general it is better to err on the side of LESS amplification than more amplification. See similar questions...

Sorry. Just kidding. Yes, of course we do. We have about 100,000 tubes in stock of the several major types we use. See similar questions...

You can use a QSC DataPort cable to connect an amplifier to the DCM. An advantage of a custom DataPort cable is that the audio pairs are shielded separately from the data lines. DataPort cables can be purchased by visiting the QSC store at www.qscstore.com or by calling QSC Technical Services Group at 1-800-772-2834 (outside USA call 1-714-957-7150). As an alternative you can use a standard 15-pin, male-to-male VGA cable where all the pins are wired through. See similar questions...

Not technically, but some cable operators require that you do subscribe to basic analog cable TV service before you sign up for high speed Internet access. Check with your local cable company for specific information. See similar questions...

The impedance of your cabinet should match the impedance stated on the back of your amplifier with regards to valve amplifiers these will normally have a selector or different speaker sockets for different impedances. See similar questions...

The Tactile Sound Tables need 2 dedicated amplifiers, much the same as using a powered sub woofer in your surround sound system. The Sound Therapy / Harp Therapy Tables need one dedicated amp. These dedicated amps allow the vibration to be adjusted in See similar questions...

The amplifier box matches the headset signal levels to those needed by the phone you connect to. Since manufacturers vary phone connections and signal levels, the amplifier compensates for these differences. See similar questions...

Yes. You will need either self-powered speakers or an amplifier as the Denzel has no built-in amplifier Yes. There is an optical S/PDIF input available on the system that will process Dolby Digital sources. See similar questions...

Yes. Since a bass guitar has no acoustic resonator, the instrument needs to be amplified electronically. This is done by a 'Bass' Amplifier. See similar questions...

It depends what style and ensemble you play in. If you are playing in acoustic ensembles like Orchestra, Concert Bands etc, then you don't need to be amplified. If you are playing in modern ensembles like Jazz, Country and Rock bands, then you will need to get a pickup and bass amplifier. See similar questions...

A headphone amplifier, or headphone amp, is simply a small amplifier specifically designed to drive the miniature audio drivers inside headphones. Because headphones are often used in portable applications, many headphone amps are conveniently battery powered. Headphone amps can also be used in a work station or desktop setting where they sometimes act as a switch between various sound sources or as a pre-amp for powered desktop speakers. See similar questions...

Yes. Unplug the amplifier from its power source any time you make a change to the system. This is especially true when an antenna is removed from the system. This prevents possible damage to the amplifier. See similar questions...

We recommend all power valves are replaced at the same time you use matched valves and the amplifier will need to be biased to match your new valves. All work of this nature must be carried out by a qualified engineer. See similar questions...

We recommend a speaker cabinet is connected to Marshall Amplifiers at all times. Failure to do this can and will cause damage to your amplifier. The vent on the top of your unit is part of the ventilation to keep the valves running at the correct temperature; the top and back grill must have a good air flow at all times as is if it is restricted this can and will cause damage.
