Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofer and test.
10、Driver Function (Woofer) 1. Remove woofer from cabinet; detach + and - wire clips. 2. Check DC resistance of woofer; it should be 3.4 ohms 10%. 3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator

12、del: Beta CSW-10 Subject: Premature Limiting A small number of CSW-10 subwoofers may limit the amplifer output prematurely when they are driven to high volume levels. This may result in the subwoofer “popping”, and then a lower than normal output. A normal output will not return until the volume is
13、decreased, or the subwoofer is switched Off, then On again. In the event you receive a CSW-10 subwoofer with a complaint of “Premature Limiting When Driven At High Levels”, follow the procedure below to correct this condition: Synopsis: Add two diodes to the limiter section on the MAIN PCB, D90 and
14、D91. 1) Remove the amplifier assembly from the cabinet by removing the (12) screws located around the perimeter of the plate (Red circles in image); it will still be connected by the speaker wires. 2) Remove the (2) screws used to secure the plastic cover to the amp panel (Blue arrows in image), sep
15、arate the panel from the plastic cover, and unplug the speaker wires from MAIN PCB (Red (this amplifier is configured in BRIDGE mode and a Ground connection to any of its terminals could cause a malfunction). 11) Connect the unit to a 120V source (or 230V for 230 models); Turn ON AC Main power switc
16、h. 12) Increase the gain control to MAX for few seconds and verify the signal on the scope; clipping must be symmetrical and should extend to the 60V area (positive turn AC mains switch to OFF and disconnect the unit from the AC source. 14) Re-install the amplifier assembly into the cabinet. FINAL T
17、EST 15) Connect the unit to a 120V source (or 230V for 230 models); Turn ON AC Main power switch. 16) Connect a Sine wave signal: 50Hz, 0.100VRMS signal to the amplifier Left or Right input. 17) Increase gain control to MAX and make sure that unit produces sound, make sure that there is no evidence
18、of air leaks or any other objectionable sound by moving the gain control up and down. 18) Turn OFF AC Main power switch, disconnect the unit from the AC source and reset the Gain control to minimum.
