Audio ground will then be referenced from the signal source and the chassis ground will be separate but still connected to mechanical ground for jgl protection. See the section on Grounding and Figure 6, for illustration of barrier strip connections. If you purchase more than one item from us, they may arrive in separate packages. Multiple Inputs may thus be connected in parallel to the same source with ease and no loss of signal level.

Some method of locking the power amplifier level controls 525 at least marking the desired settings is recommended. Without this path the unit might be a shock hazard. Sell now – Have one to sell?

Subjective evaluation should be made while seated in the normal listening location. Correct use of the ohm transmission line requires a signal source with an exact ohm jbbl Impedance, and a receiving device which also has a ohm input impedance. The “correct” polarity in such a case will be that which yields the most natural quality with a variety of program material.

However, most modern audio systems do not require the use of ohm transmission line practices. The AC power cord should not be connected to the power receptacle. Much of the early equipment used for public address systems, recording, broadcast and reproduction of sound was either designed by or heavily influenced jl the scientists and engineers at Bell Telephone Laboratories. Object i ve Method of Polarity D e termination The following test equipment is necessary; a.

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

Damage claims must be made by you. Using this wiring system the worst that would happen with a broken shield would be a rise in noise or hum due to the lack of shielding. These instructions are Intended for use by qualified personnel only. In some instances the voltage difference between the grounds will be so great that a direct connection to mechanical ground is not possible without hum in the equalizer output.

In addition, a good quality ground on the chassis provides shielding from external fields and mininriizes radiation of internal fields to the outside world.
