Hi there. Standby should be connected to 12V to turn on the amp. Information is provided without warranty, either expressed or implied. shaft which, subsequently, connects to the motor. Si me pudiera ayudar lo agradecería muncho. There are two fixes: 1) Replace the potentiometer and hope for less error, or 2) Implement attenuation circuitry at the audio input (series resistors), such that the maximum counter-clockwise position of the potentiometer is avoided. because unfortunately i can’t understand the schematics and PCB diagrams . The big advantage of this mod is that you will never have to fiddle with a control pod again, my z-2300’s are basically mini-PA systems, using any medium power 8 ohm speakers found at thriftshops. Thanks for your knowledge page and effort ! By that, I mean, can I cut two of the four leads from the RCA input from the circuit board and solder that (An LFE input) into the subwoofer inputs to the sub amp and get it to work? I’m in the process of almost exactly the same project (z-340 sub hack)! All other speakers are connected by a phono lead 13%(14). The reasoning is below: Normally, this amp takes a line level stereo channel and does three things with it. If the amp is outputting the correct voltages, then perhaps the fault is in the satellites or it’s cables. Several people have lost their control pods during moves; some have dropped or otherwise broken them; some want to tap into the circuitry for unique modifications (often multiple subwoofers…); some, like me, just wanted a better performing volume control. I need to look no further!

L. great sound. The only thing similar to this that I’ve got experience with was an Acoustimass Module woofer which was easy, all I had to do was find the LR channels through the serial port and Fortunately, everything here is simple. can somebody help me? What do you think is wrong? What are you asking for? losses or continue to create profits in his business, there are always unavoidable losses and profits will Free shipping . Your Z-2300 speakers are easy to use and produce. Thanks very much for this but where can I buy the PCB? They are dirt cheap if the control is missing or dead. What?!

Shares. I have attempted to reconnect it back up as per where it connects and seems to align with schematic. Is there a way to get an LFE (single RCA) input into this system without having to procure a remote? Someone with more free time may wish to investigate the frequency response with and without these parts. i recently purchase the same subwoofer, but without the min din cable. Learn how your comment data is processed. – Here’s the deal: It would be unethical of me to release the schematic and/or circuit board for public usage, and quite possibly a breach of Logitech’s intellectual property. But i do not understand what pins to connect to the pots, and where the resistor are supposed to go. to find the best strategy to minimize losses and deposit profits at any time. I did try building one with local supplier parts based on schematic but wasn’t successful. I can see how the cost of labor for repairs could be less than profitable, but surely it would be cheaper to send out small replacement parts rather than entire product sets. of the gambling industry. Which leads do I need to solder to the circuit board to come in from the receiver pre-amp out? There’s a lot of pressure inside the enclosure when really playing loud. A JVC bookshelf stereo FS-7000 for 14.99 (with the nice hardwood speakers) sounds great, but no bass from tiny speakers. Anyways, I figured I’d try to fix one myself, this post is pretty helpfull. iNeedFixin.com” href=”http://www.ineedfixin.com”>purchased from an independent builder. I did not need or want a second Z-2300 set (at the time). The chip is a TDA7375, which is actually a car amp. I’d confirm the audio source is good. And would you please kindly tell me how to do with the black cable on the position on WA1? have a negative connotation regardless of whether the person is well-off FREE Shipping by Amazon. The resulting signal without the r106-r105 divider would be way to high for the bass amplifier section’s inputs. For example, get an old VGA cable, join wires of pin 5 & 15 together for power to stay on; A while ago I hosted an area at a dancefestival where all other area’s used Funktion One speakersystems but quite a lot of people noticed our area as being more warm, rich sounding, more relaxing for the ears even when it was shockingly loud. Be sure to apply generous amounts of glue/gunk to avoid hissing through its holes. The front right speaker would have had the inputs and controls in it .

You are on your own. https://drive.google.com/file/d/1kkOiZNwzi9v4lZd2Tj25LMCQjtNINoyEfg/view?usp=sharing, Even a way to test if the sub woofer is working by bypassing the remote would be useful. The filtering for the bass and high signals is all done in the z-2300’s preamp section with active filters, the pod is just a passive device for convenience but it does make the design a bit unlogical.
