There is also a "Cycle Mode" where you can add a switch to cycle through the EQ settings, it is up to you, just follow the data sheet. It is a little tough since it is a surface mount resistor, but be patient. So, I needed to remove the resistor in R83 and move it to the R80 spot. This way, I can change the sound by using the iPod's internal EQ. I looked at the frequency response chart and decided that I would set the Boom Box EQ to the "Flat" setting with the Bass Boost still in place. Check out the data sheet here: Data Sheet The JVC unit uses a preamp equalizer chip from Princeton Technology and it is relatively simple to modify it so that you can change the frequency response of the EQ, remove the Bass Boost feature and even add a 3D effect. The Boom Box sounds good as is but it is heavy on the bass and you'll really have to set your iPod EQ to FLAT in order to get a nice tone. Put everything back together and test that your iPod charges when you turn on power to the Boom Box. Use double sided foam tape to join the two connector boards and use the original screws to install in the cradle. All others will be left disconnected.ģ - Fan On (connect to + to turn on - I left it disconnected) Note that I've only listed the relevant pinouts. Using the outlined pinouts, use the leads from the original Sirius connector to hook up our iPod connector to the boom box control board. We need to do this in order for the connector to fit in the existing opening.Ĭarefully solder two jumpers as shown, these are the power and ground leads that were lost when we cut the board. You can use any iPod dock to do this but I recommend any cheap one that allows you to charge the unit while plugged in.Ĭut the circuit board along the yellow line and sand smooth. Remove the Sirius connector board assembly by removing the two screws holding it in place (keep the screws). Separate the two halves, unplug the speakers and put aside the rear portion for now. If you haven't already done so, take the boom box apart by removing the six screws on the back of the unit. We'll go ahead and make the KS-SB200 into a true iPod accessory by adding a working dock that will connect the iPod directly to the boom box and charge the unit as well. I divided this Instructable into different levels: You can stop at Level 1 and get simple amplification of your iPod or go further to fully mod this Boom Box into a completely customized machine. I am not the first one to come up with the idea of using these for iPod use but there is no published COMPLETE "hack" or instructions for doing this (There is ONE website which published one but IMO the instructions were limited and had a couple of critical mistakes). Well I guess the idea didn't work out too well and you can now find these Boom Boxes on a number of places on the web for $20 - $40. Instead, re-purpose an existing product save lots of money, have fun making it and stop global warming :PĪ while back the folks at Sirius radio teamed up with JVC and came out with a boom box for their KT-SR2000 Sirius Satellite Radio Tuner. However, anything that is any good will cost AT LEAST $100 (probably much more). Yeah, I know there are TONS of items out there that let you plug in your iPod on the road.
