Equinox may be gone but the info from this blog keeps rockin'!

Stop asking me and just go visit this shop
at #249 Street 107. It is west of Monivong 
and just south of Yugoslav Blvd. Take a 
flashlight and a Khmer-English dictionary. 
It is a fun place to look around at least 
once during your stay in Phnom Penh.

Yes, Equinox is gone and everyone thinks they can pick my brain for a cup of coffee. Not so! However, a common question I have heard 3,271 times in the past month is: "Where is the best place to get (insert item here that pertains to sound systems)?
Well, F-I-I-K!

Hmmm, wait., well, here it is! 

 Well, F-I-I-K! Yes, good audio gear is expensive but a lot of good stuff from Japan can be bought here second hand (or "dead left" in Jamaican patoi): "Business Name in Khmer Language" located at #249 Street 107, but if your looking for amps, eq's, small mixers, and speakers, it's worth stopping by here. WARNING: Japan country voltage is 100volts AC. Luckily it is easy to upgrade electronics to 220 volts AC. FYI, I am a consultant now, this blog entry is a freebie! Good luck- you'll need it!

And if your are S.O.L- contact me for consulting... if your missing live music in Phnom Penh, here's your chance to contain those blues... visit the Equinox Archives Online Museum today.

Not again- not going to buy the whole unit!

Text  to come soon.... or later.

At least the motors have been good 
after years and years of making cocktails.

BANG - WTF - Small, small... SOL

This Is Cambodia (T.I.C.)

The Pchum Ben three day holiday in Cambodia was a great time to clean and check the PA system at Equinox. After 3 days of close inspection and hard work, I turned everything on to check. Two minutes after being switched on- BANG! and a puff of smoke came out of the Behringer SX3242FX sound mixer.
NSP1200 IC chip blown in the power supply.


No shop could repair , nor were replacement part available... I searched for a schematic diagram for an hour and finally found this...
SX3242FX Power Supply Schematic (Diagram A)

Voltage output (Diagram B)

All that was need was steady voltages of +5, +15, -15, aqnd +48 volts. Well, it was close enough to a desktop PC computer supply. I analyzed the circuits and the 15 volts is used to light up the LEDs. So I took the chance the LEDs would work with 20% less voltage. The +48 is for the microphone phantom power and I already had this.

Used Dell PC power supply I had.

Taking a computer power supply I soldered it  to the mixers power connector.

Soldered the wires, see Diagram C below.
Input location on mixer circuit board.
I  checked the voltages, plugged it in and it worked.
I ran an extra wire for the +48 volts later and  
ground wire to the metal chassis.

I was very happy this worked.
I just have to install the board and ready for the next show at Equinox.

Special thanks to the band SONIC DETERGENT for the understanding and support while I figured this out.

UPDATE: The used Dell power supply I was using failed. So when using another power supply, I added connectors to make swapping units easier.
