Boston Acoustics PV600 Subwoofer

My 5-yr old unit keeps blowing fuses imediately after replacement. Amp is off so it is a power supply issue. Any ideas? Thank you

    Got same problem with mine. You can do a quick check to isolate portions if you are technically inclined. Open back of unit and follow wiring from mains transformer. There should be 2x Red wires and 1x yellow wire leaving the transformer to the power pcb. They plug onto the pcb with spade connectors. Remove them and wind some insulation tape around the ends to prevent shorting. Replace the fuse and apply mains again. If the fuse still blows then it is the mains transformer. This can be purchase through any electronics supplier if shown the original.

    If fues does not blow, then reconnect wires. Reapply power and check if fuse blows. If it blows this time then the pcb is suspect. You would then need to have an electronics expert look at it for you then.

Chances are you have a bad bridge rectifier or diode causing the fuse to blow as transformers seldom give issues. This really isn't a hard problem to fix, there will be at least one larger capacitor fairly close to where the 2 red wires go into the PCB, that capacitor will hook to the diodes, there may be 4 separate diodes or it could be a diode bank with all 4 diodes in one enclosure, if you have a volt meter you can test and see if you get a short across the terminals, just set the dial on the meter to ohms x1 and I'm guessing you will see the meter go to 0 ohms, if you change the diode that is shorted or the bank there is a good chance it will work, your going to need some basic soldering skills though to fix it...good luck!!

SOURCE: how do i connect my boston acoustics pv800

You need to use the LINE LEVEL connection on the pv800 (usually a rca type connector cable) and run this cable into the back of the HK 520 Subwoofer PRE-OUT connector, be sure the HK Receiver menu speaker set-up option is set to SUBWOOFER "YES"

How do you repair blown Boston Acoustics Subwoofer MCS Amp?


Most often this unit goes dead because of zener diode ZD3 shorting. It is a 18v zener. replace this and you should be back in business.

Boston micro 95pv sub-woofer is blowing 3A Slow Blow fuses.

Loud humming sound


Make sure that the input connection ground is good. If that does not cure the loud hum then you have a power supply issue.

Boston Acoustics Recepter Radio HD stopped working - no power. The power supply is fine. is there a fuse in the radio?


There should be a fuse in the back but it would only blow if the wiring is funny because the car's fuses are closer to the power supply and should go first, but try anyway

I get a red light on the back panel labeled power. No green light. I don't think the PV 600 is working but when I run the channel check through my Pioneer THX receiver I hear sound. Any thoughts?


The PV600 and PV400 have auto-on circuitry that turns the subwoofer on when a signal is presented, and turns off if no signal is detected for 15 minutes.

http://www.retrevo.com/support/Boston-Acoustics-PV600-Subwoofers-manual/id/522dj484/t/2/

Not knowing which Pioneer receiver you have I have dropped in the steps for No Sound from Subwoofer:

• Check that the subwoofer is connected properly, switched on and the volume turned up.

• If your subwoofer has a sleep function, make sure it is switched off.

• Make sure that the Subwoofer setting is YES or PLUS (see Speaker Setting on page xx).

• The crossover frequency may be set too low; try setting it higher to match the characteristics of your other speakers (see Speaker Setting on page xx)

• If there is very little low frequency information in the source material, change your speaker settings to Front: SMALL / Subwoofer: YES , or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on page xx).

• Check that the LFE channel is not set to -80dB , or a very quiet setting (see Bass Peak Level

on page xx).

• Check the speaker level settings (see Channel Level on page xx).

Regarding the Large vs Small assignment of speakers, what they mean isn't so much the physical size but the ability to handle real bass. Large if Yes.
