Repairs and Warranty This product is warranted by the manufacturer to the original purchaser against defects in material and workmanship for a period of one year from the date of purchase.

My unobtainium Right now I am checking my components and the other upgrades that I need to make to my PS upgrade, IC replacements with OPA, various other changes gleaned from these forums before mounting the new bjl.

Even if the previous piece of equipment has an unbalanced output it may be advantageous to wire it to the input of the as though it were balanced. Reverse the polarity of the high frequency loudspeaker, which will produce a change in voice character.

Inadvertent exchange of low and high frequency output connections at thethe power amplifiers, or the transducers may result in severe damage to midrange or high frequency loudspeaker system components.

If different loudspeaker systems are used, or in a stereo system, first establish common polarity among the low frequency drivers as follows: A loudspeaker is “in polarity” if, for a positive-going input signal, jnl produces a positive pressure wave compression as opposed to rarefaction. Thanks for sharing and nice to know! But there are instances where a hum or buzz will be Introduced due to a phenomenon known as a ground loop. Please enter a number less than or equal to 1.

Figure 4 shows the factory preset psltlon binary code Installation of the Electronic Frequency Dividing Network Involves opening the bjl to gain access to internal circuit modules and programming switches. If the input source is unbalanced, an isolation transformer should be used at the source device’s output. Power Requirements; lOW Max. Correct system wiring will be verified if the treble component of the program material increases in level and is emerging from the high frequency driver.

To optimize the results obtained with this procedure, the loudspeaker systems should be placed in their normal operating locations. Replace the bottom cover, observing the proper orientation.

As noted earlier, the may be rack mounted in 5325 different ways: Employing the Figures 8, 9 and bjl illustrate various biamplified and triamplified systems; these show typical examples of applications, although by no means are they all-inclusive.

The Security Cover may be cleaned with any mild, non- abrasive cleaner and a clean cloth. Multiple Inputs may thus be connected in parallel to the same source with ease and no loss of signal level. Winning bidder is responsible for shipping charges. The unit is now ready for mounting and connection of the various inputs and outputs. Minimum monthly payments are required. All others use the first six pins only.

If subjective analysis is to be used and the power amplifiers are equipped jl level controls, initially adjust those controls to one half their rotation and then regulate as necessary.


Proper transducer polarity is indicated by the flattest frequency response through the crossover region as shown by the RTA.

Method of Polarity Determination The following method is recommended to establish proper polarity of the loudspeaker system when no test equipment is available. Salesbaron is in Los Angeles, Subject to credit approval. For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab This amount includes applicable customs duties, taxes, brokerage and other fees.

If in doubt, always test the low frequency loudspeaker s first, since the presence of high frequencies there will be less apt to cause damage than the converse.

We have limited this discussion to the method of establishing the correct signal polarity for the components in any one channel multi-way system, as well as the correct polarity relationship between channels.

If it can be determined that the defect is associated with one of the plug In crossover modules by substitution or otherwise, it is only necessary to return the module.

If the crossover point lies above 2 kHz, reversing the polarity of the high frequency driver will create little if any perceptible difference in system performance. Without high-pass filtering, subsonic signal content can waste amplifier power lowering the available headroomand Induce distortion in audible regions by modulating the higher bass and midrange frequencies.

The only changes that I have needed to make are to drill out the holes on the L-brackets jbp the corresponding holes in 52335 boards to take the bolts that I am using.
