4、aker system. The new 601 Series II speaker incorporates two new concepts in speaker technology: The Free Space array, which allows the drivers to radiate freely in any direction, providing exceptionally realistic and natural-sounding energy distributing in almost any listening room. The second new c

5、oncept is the Sub-port Enclosure System, figure 1. Each woofer has its own enclosure that has damping material and a sub-port. The sub-ports are tuned to operate in the frequency range of 200-300Hz, providing principal sound radiation in these frequencies through the sub-port rather than the cone. T

6、he sub-ports are coupled to the main port of the speaker, and with the new extended range woofers, tweeters and crossover network, the 601 II speaker takes maximum advantage of this new technology. SPEAKER CONFIGURATION WOOFER: Two new high-efficiency 8 woofers designed for the sub-port enclosure. E

7、ach woofer has a long excursion voice coil and suspension, plus a 14 Oz. magnet, providing high output capability. Uniform response of the woofer is over 2.5KHz with use of the Dual Frequency crossover network. One woofer is directed forward while the second woofer is directed upward, which helps cr

8、eate a balance of reflected and direct energy in the listening room. TWEETER: Four 3 wide-range high sensitivity tweeters per enclosure provide flat power radiation beyond 15KHz. The response extends down to 1.5KHz for use with the Dual Fre- quency crossover network. Two tweeters in each speaker enc

9、losure are directed outward so that most of the sound energy is reflected off the back and side walls. One tweeter is posi- tioned so that the sound energy is directed towards the center of the room and the final tweeter is positioned to reflect sound off the back wall between the speakers and into

10、the room, providing a strong center stereo image by filling the hole in the middle. DUAL FREQUENCY CROSSOVER NETWORK: Located in the top woofer cup, the crossover network consists of two capacitors, two resistors, and two tweeter protection lamps. The Dual Frequency crossover network is designed to

11、offer performance advantages by deliberately operating both the woofers and tweeters simultaneously over a significant part of the frequency range. We have designed the crossover network to have separate transition frequencies for the woofers and tweeters. By using separate frequencies, an overlap i

12、n response of almost one octave is achieved, providing smoother frequency response in the crossover region. Careful design of all components in the crossover network matches woofer and tweeter re- sponse, eliminating phase cancellation and assuring accurate frequency and transient re- sponse. Enclos

13、ure: A sub-port enclosure system for maximum efficiency, minimum cone motion and placement versatility. Cabinet is constructed of walnut grain vinyl laminated to particle board. Note: The early version of the 601 II speaker has three input terminals. Later versions had two input terminals. Refer to

Sweep Test 1.1

16、 Apply a 10Vrms, 15HZ signal to the input terminals of the speaker. 1.2 Sweep the oscillator from 15HZ to 2.5kHZ. There should not be any loud extraneous noises coming from the woofer. Note: The woofers are wired in series. If one woofer is open the other one will not work. 1.3 Sweep the oscillator

17、from 1.5kHZ to 15kHZ. Replace any tweeter that is inop- erative or buzzing. 2. Rub and Tick Test 2.1 Apply a 10Vrms, 25HZ signal to the input terminals of the speaker. 2.2 No extraneous noises such as rubbing, scraping or ticking should be heard. Note: To distinguish between normal suspension noise

18、and rubs or ticks, dis- place the cone of the driver slightly with your fingers. If the noise can be made to go away or get worse, it is a rub or tick and the driver should be replaced. If the noise stays the same, it is normal suspension noise and it will not be heard with program mate- rial. 3. Ai

19、r Leak Test 3.1 Apply a 10Vrms, 40HZ signal to the input terminals of the speaker. 3.2 Listen for any whooshing sound com- ing from the cabinet or around the woofer. Repair any air leaks. 4. Phase Test 4.1 Momentarily apply 10VDC to the input terminal of the speaker. Observe the polarity when connec

20、ting the DC supply. 4.2 The woofer should move outwards with the momentarily applied DC voltage. 4.3 Visually check the tweeters wiring to ensure proper phasing. 5 DISASSEMBLY/ASSEMBLY PROCEDURES 1. Grille Removal 1.1 Reach behind the top part of the grille and gently lift up on the grille. 1.2 Once

21、 the grille has been pulled off of the four top clips, gently pull the grille away from the front of the speaker, removing it from the two clips on the lower part of the cabinet. 2. Grille Replacement 2.1 Place the top of the grille on the top of the cabinet so that the four clips on the grille are

22、aligned with the four grommets on the cabinet. Press the clips into the grom- mets so that they snap into place. 2.2 Place the lower part of the grille onto the front of the cabinet so that the clips on the grille align with the grommets on the cabinet. Press the clips into the grommets so that they

23、 snap into place. 3. Woofer Removal 3.1 Perform procedure 1. 3.2 Remove the four screws that secure the woofer and the dress ring to the cabi- net. Lift the woofer out from the cabinet. Note: Reuse the dress ring. 3.3 Cut the wires as close to the woofer terminals as possible. Note: Make a note of t

24、he wiring configura- tion. 4. Woofer Replacement 4.1 Strip the wires and connect them to the woofer. Use the schematic diagrams on page 7and 8 to ensure proper wiring. 4.2 Replace the four screws that secure the woofer and the dress ring to the cabi- net. Note: The replacement woofer will come with

25、a dress ring that is not glued to the woofer. Remove the dress ring from the replacement woofer and discard it. 5. Tweeter Removal 5.1 Perform procedure 1. 5.2 Perform Procedure 3. It is necessary to remove the woofer to gain access to the tweeters service loop. Removing the woofer will also prevent

26、 accidental damage to the woofer. 5.3 Remove the screw that secures the tweeter to the tweeter bracket. 5.4 Cut the wires as close to the tweeter as possible. Note: Make a note of the wiring configura- tion. 6. Tweeter Replacement 6.1 Strip the wires and connect them to the replacement tweeter. Use

27、the schematic on page 7 and 8 to ensure proper wiring. 6.2 Replace the screw that secures the tweeter to the tweeter bracket. Pull the excess wires back into the cabinet and twist them so that they do not cause a buzz. 7. Crossover Access 7.1 Perform procedure 1. 7.2 Remove the top woofer. 7.3 The c

28、rossover is located under and in front of the top woofer. 6 601 II PART LIST CROSSOVER COMPONENTS Two TerminalThree Terminals DescriptionPart Number Capacitor, 3.4uF, 5%106825 Capacitor, 4.0uF, 5%108980 Capacitor, 3.0uF, 5%104130 Resistor, 3.9, 15W119094-3R9 Resistor, 3.0, 15W119094-3R0 Resistor, 5.
