I need schematic for 450 signal bridge - Toys

RMS Power Rating:

• 150 watts x 2 chan. @ 4 ohms
• 300 watts x 2 chan. @ 2 ohms
• 450 watts x 2 chan. @ 1 ohm
• Bridged, 300 watts x 1 chan. @ 4 ohms
• Bridged, 600 watts x 1 chan. @ 2 ohms

Nice amplifier. However it is best suited for speakers and not for sub woofers. Connect the plus (+) from speaker output 1 and the minus (-) from speaker output 2. Connect the plus (+) from speaker output 3 and the minus (-) from speaker output 4. Now the amplifier is in bridge mode, which will give you 300 WATT RMS at 4 OHM load. If you are bridging the amplifier to run sub woofers then do not forget to set the X- Over to LPF on the channels that you are planning to bridge. Whatever you do, make sure that the load you are asking the amplifier to play is no lower than 4 OHM. Playing this amplifier in bridged mode lower than 4 OHM is a recipe for trouble.

Follow these steps :
•1
Reset the bridge. Accomplish this by manually disconnecting the power source from the wall or the back of the bridge. Leave it disconnected for 30 seconds to a minute so that the software contained therein can fully reset. Reconnect the bridge and wait two to three minutes until the network is back up and running again. In many cases, a simple reset can solve your network-related bridge problems.
•2
Ascertain whether there is network activity on your computers. Accomplish this by looking at the back of each computer at the network card. There should be two lights next to your Ethernet port--at least one of these lights should be completely lit without flickering. This indicates that the network card in the machine is operational and ready to receive a signal, eliminating that as a possible problem source.
•3
Move the bridge to a different location to determine whether interference is preventing the network computers from receiving a proper signal. If possible, relocate the bridge to the same room in which the computers are located and try to reset the connection again.
•4
Determine whether the bridge has failed altogether or whether the wireless signal from the bridge has failed. Accomplish this by physically connecting the computers to the wireless bridge through the use of Ethernet cables. If this restores network connectivity, you know that the only problem with the bridge is the wireless signal emission.

This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.

Here are the specs for the AMP:

Channel # Capability 1/2/3

PWM Regulated MOSFET Power Supply

Screw-Type Speaker Terminals

Balanced Isolator Input Circuit

RCA Inputs 2 Channel

Input Level Control Hi-Volt (200mV ~ 6.5v)

Built-in Crossover Selectable LPF (80Hz, -12dB/Oct.)

In order to get the bass you want, you'll run your amp switched as a two channel amp and you'll need to run your subwoofers in 4 ohm Mono that's 450 x 2 to give you 900 watts of power.

2, 2 ohm dual voice coils ran in series and bridged on the amp for each sub.

Otherwise, Single Voice Coil 4 ohm subwoofers bridged to amp.

After careful inspection, a hard rubber roller that is part of the tape take up mechanism, has fallen off. Located and removed from casing. Still need schematic of JVC GR-DF 450 Mini DV to secure roller back on.

ohms are impedance or the amount of current being blocked through the line. The lower the ohms the less resistance. Speakers run at a certain ohm (or at least are recommended to run at). Have you bridged your amp? Usually when you bridge your amp it lowers the ohms by half. You may have damaged something, especially if you bridged your amp and didn't bridge it properly.

The output of the transformer goes to a RS404L bridge Rectifier. the 4700uF cap are leaking. Did you work in this area?
