It features a high-precision 15”

6、transducer combined with application specific amplifier technology. The system is composed of a single, compact subwoofer cabinet with built-in control and amplifier electronics. The SRS1500 accepts a stereo line-level signal via female XLR input jacks. Male XLR Thru jacks are provided for daisy-cha

7、ining the signal to additional SRS1500 cabinets. The built- in crossover separates the low frequencies from the high frequencies, and routes the high frequencies to the male XLR high-pass output jacks. Connect these to the inputs of full- range active speakers such as the Mackie Designs SRM450s, or

8、to an amplifier powering a pair of passive speakers such as the Mackie Designs M1400i and C300s. A Phase switch gives you the option of reversing the phase to the full-range speakers by 180. A Subwoofer Level control allows you to adjust the balance between the subwoofer and the full-range speakers.

9、 The built-in amplifier produces up to 600 watts of power. The amplifier module sits on a large heatsink that eliminates the need for fans, dramatically extending life expectancy, and eliminating maintenance cycles. A tremendous benefit of having the amplifier located within the subwoofer cabinet is

10、 the speed with which power is delivered to the woofer. The cabinet is constructed with 18mm thick multi-layered birch plywood. Carrying handles are integrated into each side for easy loading and transport. POWER Switch Use this switch to turn the SRS1500 on and off. Make sure the signal sources lev

11、el control is turned down before you turn it on. AC Receptacle This is where you connect the AC linecord to provide AC power to the SRS1500s built-in power amplifiers. Plug the linecord into an AC socket properly configured for your particular model. THERMAL Indicator The SRS1500 has a thermal prote

12、ction circuit that monitors the internal temperature of the amplifier and heatsink. If the temperature should exceed a safe operating level, the signal is muted and the THERMAL indicator lights. When the temperature cools to a safe level once again, the thermal protection circuit deactivates and nor

13、mal operation continues. Note: Activation of the thermal protection circuit is an indication that you must take steps to avoid continued thermal problems. POWER Indicator When the POWER switch is turned on and the linecord is connected to an active AC power supply, this indicator lights green. The b

14、lue LED on the front of the cabinet works in the same way. 5 POWERTHERMAL THRU (FULL RANGE OUTPUT) HIGH PASS (MID/HIGH FREQ) OUTPUT SUBWOOFER CONTROLFULL RANGE INPUT PARALLEL 120Hz ON OFF NORMAL REV 180 PHASE 120 VAC 60HZ 350W POWER L R L R SUBWOOFER LEVEL (+4dBu ) NORMAL +15OO INOUT FULL RANGE INPU

HIGH PASS (MID/HIGH FREQ) OUTPUT These are male XLR-type connectors that produce the frequencies above 120Hz. Connect these to a pair of full

17、-range active speakers or to an amplifer/passive speaker combination. The SRS1500 reproduces the frequencies below 120Hz. SUBWOOFER LEVEL Control This adjusts the subwoofer level. Use this control to balance the volume between the subwoofer and the full-range speakers. The center detent position is

18、+4 dBu gain, which is the normal position. Unity gain is at the 9 oclock position. PHASE This switch reverses the phase of the signal at the HIGH PASS OUTPUT jacks. Depending on the placement of the SRS1500 subwoofer relative to the full-range speakers, you may get a better low-frequency response in

19、 the room if you reverse the phase of the signal. 6 Specifications General Specifications Freq. Range40Hz120Hz Freq.

22、 the following leakage test before returning the unit to your 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 t

23、he unit under test. 2.Connect the unit under test to an AC power 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 recepti

24、cal so the hot and neutral are swapped. Verify that the reading 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.
