KAB SX-1200

   KAB began its relationship with the 1200 in 1994 with our Broadcast Standard version which featured 78 rpm. We were the first to introduce the 1200 to audiophiles, when we began selling the TD-1200 tonearm fluid damping system in 2000. We introduced the very first outboard regulated power supply for the SL1200 in 2003.

   While developing the PS-1200 outboard power supply, internal measurements showed a high frequency pulse noise interference being generated by the strobe lamp itself. Since the strobe lamp is only needed to set speed changes, it seemed like a wise idea to develop a strobe on/off switch.

Since it is KAB policy never to remove standard features nor cosmetically alter the "look" of the SL-1200, I did not want to simply disonnect the strobe, as there are times when it is useful to see the speed pattern. So I developed the SX1200 which allows you to turn the strobe lamp on or off at will. The circuit installs quickly with only 3 wire connections. In use you simply hold the start-stop button down for 5 seconds and the lamp will disable. Hold again for 5 seconds and the lamp returns on. The lamp will self test at power on and then automatically extinguish after approx 7-10 seconds.

The elimination of this 100 mA noise pulse further improves the efficiency of the internal voltage regulator and may improve micro motor control by eliminating a source of noise contamination. And remember, you can also update the old internal regulator with our new DC-1200 voltage regulator. This new update takes even tighter control over power distribution throughout your 1200. The SX-1200 fits all SL-1200MK2-6 only.

• Simple 3 wire hookup
• Shipping Weight 0.5 Lbs

   Built for reliability, I chose a digital timing approach using reliable CMOS integrated circuits. A CD4093 serves to buffer the input and provide a steady pulse generator. A CD4017 decade counter serves to divide and extend the action time. A CD4013 flip flop produces the alternate on-off-on action.

   In use, the CD4093 generates one pulse per second when triggered. The CD4017 is tapped at the #6 output and so indicates every 6 seconds triggering the CD4013 flip flop. This in turn gates a transistor switch which finally turns the strobe lamp on or off.

• 1 Year Warranty
• Easy Hookup
• Neat Hidden Operation

   The really great features to take note of with the SX-1200 are the easy hookup and the peace of mind having control over the strobe lamp offers

   The strobe lamp is not an obvious source of noise, but in reality the 100mA current spikes are quite substantial.

   The neat hidden circuit keeps the clean appearance of your 1200 totally stock and clean.

Both DC-1200 and SX-1200 are included in our complete power supply system, the PS1200GX. As a complete system, the PS1200GX reigns a tight control over the power distribution within your 1200 assuring the best possible performance.

The SX1200 offers great value. No one beats KAB for performance and value.
