No sound bought new speakers and they won't work

see the connection attached. God bless you

It sounds like the vehicle has an amp that needs to be powered up. Was there an extra harness from the vehicle that you did not use? Also, check for power on the blue/white from the radio.

if the machine is still under warrenty, take it back
if it's not under warrenty, take it to the place you bought it from & tell them

i'm having the same problem ... :/ anyone please! heelp!

You don't (unless you want two B1520's on one channel and the sub on another). Reading the manuals would help.

The EP4000 amp drives only two channels. It CAN be bridged for one speaker but it won't support two channel and bridged mode simultaneously.

The B1520 subwoofeer is PASSIVE so it will need a dedicated amplifier to power it and control its volume independently of other speaker channels.

it seems like the headphones do not work anymore. Do you have any other headphones that you can use. You could also call the company that you got the headphones from and see if they can repair them or replace them for you. If you bought it from ebay or amazon just find the person you bought it from and ask them if you can send it back for a new pair.

Did you have the same speakers you test with at the store? If not, that is the problem. This unit will generate 400 watts a side when used on 4 ohm speakers, and a little over 200 watts a side with 8 ohm speakers and about 120 watts a side with 16 ohm speakers. For mics, the trim controls will be between 3 o'clock and full right. You set these using the PFL button with loudess vocal such that the indicator does not reach into the clipping. Do this for each channel. ALWAYS use balanced lines where possible. Use of unbalanced cables input results in a 6 Db loss. You will want to run the channel and main faders normally in the 80% range, like between -5 and 0 for BEST signal to noise ratio. There are good videos on You tube about mixer setup. If the speakers were not the ones tested with, your speakers may be the problem... I HOPE they are NOT consumer stereo speakers as you will soon smoke them with this mixer... the consumer speakers are very inefficient and you won't get much sound before blowing them up. If you spent less than $300 for EACH EV speaker new, it is UNLIKELY they are suitable. The suitable ones I found for 12 inch are around $600 each...hopefully these are the ones you have. There are less expensive brands. Frankly, if you want more sound, especially bass, I would go up to 15 inch speakers. These are probably the lowest end price wise to consider: http://www.musiciansfriend.com/pro-audio/behringer-b215xl-15-1000w-passive-pa-speaker Shop around, but stay with PA rated pro speakers as consumer ones just won't take it and eventually fail when used with these amps. ALSO be very careful if you use 1/4 inch speaker plugs as the SLEEVE of the A channel of this amp is the HOT, not the TIP of the jack... short the sleeve to something grounded and it is goodbye amp.

You can just add more wire. Disconnect from the amp first, so you won't short it out.

These are a nice unit... just bought three of them that were dead... I have repaired one so far. I assume you mean the blue LED is on indicating power is on. What I want you to test is if injecting signal on the BACK of the unit jack (power amp in) will create sound. If it won't then better exercise your warranty. The one unit I have completed repair had a bad 15 volt regulator in it... the second that is almost fixed somebody had blasted the input circuits... probably connected to a speaker output... don't do it... these are LINE and MIC level units. If you need to tap off a speaker output, use a DI box with the unit. The third unit I have not received yet. Drummer used the repaired one as monitor last night and was impressed with the power this unit has.

Keeping in mind that the 901's and multichannel recievers won't work unless you use an outboard amp for them, that should open up the choices pretty wide. But your MP3-compatible AVR MUST have front channel pre-outs. Any solid 100 watt x 2channel amp will drive them.
