Impedance is the load connecting to the speaker socket on the amplifier or combo to give maximum power transference. This must match the stated impedance value on the amplifier or combo to ensure no damage can be caused to the speaker or amplifier.

Unfortunately the old style selectors are no longer available. We recommend having it replaced with the new rotary selector. All work of this nature must be carried out by a qualified engineer

mdash; 30 ohms: Not recommended. Distortion will be somewhat higher (but still probably below the audible threshold) and batteries will drain faster. mdash 450 ohms: As impedance increases, distortion at normal volumes becomes vanishingly small, but headroom also decreases. gt 450 ohms: not ideal The HA-1A may not be able to drive headphones in this range, such as the AKG K240DF, to their full rated power. These headphones require higher voltages than batteries can provide.

A : The output impedance of the headphone jack is so low, that any headphone with the appropriate plug should work optimally. If you have electrostatic 'phones that use a transformer chassis, connect to the Panache's speaker outputs.

Well, high-end headphones traditionally have higher Ohm rating. The Original Boostaroo's dB output will decrease as the Ohm rating of your headphones increase. For higher-end headphones, we recommend purchasing The Boostaroo Revolution. The Revolution provides a more powerful output which will power headphones from 60-300 ohms. Glad you asked! We are always working on something new. Feel free to join our product update mailing lists. We do not SPAM you, and we do not sell our lists.

A measure of the impediment to the flow of alternating current, measured in "ohms" at a given frequency...

Well, probably. The MA 6S will not be damaged but you will obtain much less power output, and an extremely hot amplifier. To protect itself the MA 6S will current limit to the best of its ability. The MA 3 will current limit also and its fan must be set to high speed. Be forewarned that running below rated impedance voids the warranty and may damage the amplifier channels as well as power supply.

The unit of measurement when measuring the resistance of a thin film of a material using the four point probe technique. It is equal to the resistance between two electrodes on opposite sides of a theoretical square. The size of the square is unimportant.

The unit of measurement when measuring the bulk or volume resistivity of thick or homogeneous materials such as bare silicon wafers or silicon ingots, using the four point probe technique. RESISTIVITY is the inherent property of the material which gives it electrical resistance. It is sometimes called Specific Resistance. Sheet resistance is the resistance of a thin sheet of material which when multiplied by the thickness (in cm) gives the value of resistivity.

The English version of the Julian Calendar was called the "Old Style" Calendarafter they adopted the Gregorian, which was also called New Style. The onlydifference between the English Old Style and the Julian was that theyear began on March 25. That is, the day after March 24, 1711 was March 25, 1712.Because of this, I have implemented both the Julian and the Old Style calendarsin my conversion program.

Your cabinet should have a model number and rating plate on the back, if there is no rating plate the cabinet will need to have the impedance measured by an engineer. We do not recommend using the cabinet until the impedance has been checked as it could damage both your amplifier and cabinet if either is used incorrectly. If your cabinet has a rating plate the impedance of the cabinet must match the impedance of the amplifier you are connecting it to.

You can. Just make sure that you connect the ground to pin-1 and the tip to pin-2. Obviously hi-z signals are more prone to noise than balanced signals but this will still work.

The term Ohms-cm (Ohms centimeter) refers to the measurement of the "bulk" or "volume" resistivity of a semi-conductive material. Ohms-cm is used for measuring the conductivity of a three dimensional material such as a silicon ingot or a thick layer of a material. The term "Ohms-per-square" is used when measuring sheet resistance, i.e., the resistance value of a thin layer of a semi-conductive material.

It doesn’t matter. Ohms per square is the unit of an electrical measurement of surface resistivity across any given square area of a material. It is the measurement of the opposition to the movement of electrons across an area of a material's surface and normalized to a unit square. This measurement is intended to be a basic material parameter and not dependent on absolute area, length or thickness.

We don’t recommend the use of headphones for the REI Program CDs. This is mainly because it’s very easy to turn the volume up too high with recorded percussion sounds. In fact we don’t recommend headphones for anyone–it’s just too easy to turn the volume up too loud and do damage to the ears. Percussion instruments record with a very sharp auditory signal and what may sound like a normal volume may actually be damaging to the ears.

Yes. The Holosync technology is a stereo effect in which we place certain frequencies in each ear, targeting certain parts of the brain. Stereo because the sound will bleed from channel to channel. Always use stereo headphones for ANY Centerpointe soundtrack unless we SPECIFICALLY tell you that it is not required. We do sell several grades of good-quality Sony headphones for below retail prices. for more information, call our offices: 800-945-2741.

For especially loud conversations, ChatterBlocker may be more effective over headphones. However, prolonged headphone listening can be uncomfortable and can cause hearing fatigue. Often, ChatterBlocker can be surprisingly effective over speakers at low to moderate levels, without disturbing your neighbors.

Yes. Users should take care when listening to any audio content (not just ChatterBlocker) at excessive volume levels and/or for extended periods of time.

You can do that and more. We’ve helped thousands of people raise more than $140 million for cancer and we’re here to help you. Call us at (416) 815-WALK (9255) or for some tried-and-true ways to fundraise, visit the fundraising tools page. No. That fee pays for the support you'll receive prior to and during the event. Your fundraising goes 100% straight to the Princess Margaret Hospital. And once you get started you’ll realize that you can raise more than you imagined.
