It

6、features a one-piece 90 x 40 horn, which includes both the mid and high frequency sections in a proprietary “Optimal Wavefront” design. Unlike typical mid/high horn designs, the high frequency section is positioned to fire down into the six- inch mid-ranges dispersion pattern. This creates a focused

7、, single wave front with excellent phase and power response characteristics. The mid-range transducer operates between 700Hz and 3000Hz, eliminating the placement of a crossover point in the middle of critical voice frequencies. Frequencies above 3000Hz are reproduced by a 1-inch exit compression dr

8、iver. The low frequencies are produced through a high output 15-inch woofer. The SR1530 accepts a line-level signal via a female XLR input jack. A male XLR Thru jack is provided for daisy-chaining the signal to additional SR1530 cabinets. Two built-in power amplifiers provide 100 watts each for the

9、mid-frequency and high- frequency drivers. The low-frequency driver is powered by a high-efficiency, high-current Class G topology amplifier providing 300 watts of power. The amplifier modules sit on a large heatsink that eliminates the need for fans, dramatically extending life expectancy, and elim

10、inating maintenance cycles. The cabinet is constructed using both 18mm multi-layered plywood and pressure injected structural resin. Two carrying handles are integrated into each side for easy loading and transport. OVERVIEW 5 SPECIFICATIONS System Specifications Frequency Range40Hz20kHz Frequency R

20、e 16 ohm load on the Low Freq section. 2.6 Connect the variac to the AC connector of the SR1530. 2.7 Set the frequency to 200 Hz, at minimum output. 2.8 Turn on the SR1530 Power Switch 3 POWER UP 3.1 Slowly bring the Variac up to 115 Vac (230 Vac for European models). 3.2 Verify that the green led i

21、s illuminated. 3.3 Verify an ac current draw of: 340 mA 10 % (115 Vac) 170 mA 10 % (230 Vac). 3.4 Verify with a DC voltmeter the values of the two DC rails ( 25 Vdc; 50 Vdc) with a tolerance of approx 1.5 Vdc for the 25V rail and approx 2 Vdc for the 50V rail. Amplifier Test Procedure NOTE: The ampl

22、ifiers are operated in mono, so the negative output terminals must not be grounded by your test equipment. Use an oscilloscope in Differential mode. 7 4 VERIFICATION OF THE LOW FREQUENCY SECTION. 4.1 Initially set the input signal to 30 mV at 100Hz. 4.2 Increase the input signal slowly until the lim

23、iter starts to stabilize the output to 35V (approximately 76.7W) with an input of approx 250 mV. 4.3 Lower the input signal until the limiter is not operating. The input signal should be approx 220230mV) and the output signal should be 32V (approx 63.5 W into the 16 ohm load). 4.4 Bypass the limiter

24、 temporarily by shorting the led section of the optocoupler, and increase the input signal until the output signal is clipping. Verify this occurs at approx 53 volts (180 W into the 16 ohm load). The input signal should be approx 380mV. 4.5 Remove the short circuit and verify that the limiter kicks

25、in after 7 or 8 seconds. 5 VERIFICATION OF THE HIGH FREQUENCY SECTION. 5.1 Connect the analyser and scope to the 16 ohm load on the High Freq section. 5.2 Initially set the input signal to 100 mV at 10 kHz. 5.3 Increase the input signal slowly until the limiter starts to stabilize the output to 10.1

26、V (approx 6.4W into 16 ohms) with an input of approx 240 mV. 5.4 Lower the input signal until the limiter is not operating. The input signal should be approx 190200mV) and the output signal should be 7.9V (approx 3.9 W into 16 ohms). 5.5 Bypass the limiter temporarily by shorting the led section of

27、the optocoupler, and increase the input signal until the output signal is clipping. Verify this occurs at approx 19.2 volts (23 W into 16 ohms). The input signal should be approx 441 mV. 5.6 Remove the short circuit and verify that the limiter kicks in after 6 to 7 seconds. 6 VERIFICATION OF THE MID

28、 FREQUENCY SECTION. 6.1 Connect the analyser and scope to the 8 ohm load on the Mid Freq section. 6.2 Initially set the input signal to 120 mV at 1 kHz. 6.3 Increase the input signal slowly until the limiter starts to stabilizes the output to 14.6V (approx 26.7W into 8 ohms) with an input of approx.

29、 560 mV. 6.4 Lower the input signal until the limiter is not operating. The input signal should be approx 490500mV) and the output signal should be 12.9V (approx 20.9 W into 8 ohms). 6.5 Bypass the limiter temporarily by shorting the led section of the optocoupler, and increase the input signal unti

30、l the output signal is clipping. Verify this occurs at approx 24 volts (72 W into 16 ohms). The input signal should be approx 940 mV. 6.6 Remove the short circuit and verify that the limiter kicks in after 5 to 6 seconds. 8 You must perform the following leakage test before returning the unit to you

31、r customer. Take every safety precaution to protect yourself while doing this test. 1.Make a small loading RC circuit as shown in the diagram below, and connect the AC volt meter between the AC power source ground and any exposed metal on the unit under test. 2.Connect the unit under test to an AC p

32、ower source using a ground-lift adaptor, leaving the units safety ground floating. Turn the unit on. 3.The meter reading should be less than 750mVAC (note: this is equivalent to 0.5mA of leakage current). 4.Flip the plug over in the receptical so the hot and neutral are swapped. Verify that the read

33、ing is still less then 750mVAC. 5.If either reading is greater than 750mVAC, then you must investigate and repair the unit before returning it to your customer.
