Hey, i bought a new pair of samson auro D415 speakers and i connect them in parallel because one of my main mixer outputs ain't working.but even if al my signal gains and fader levels are low,the peak light goes on and the speaker switches off. I also use passive monitors with a separate power amp and it clips occasioally,since using da D415 speakers. Plz assist, thanx

Watch your impedance, when you add speakers the impedance will change. example 8 ohm speaker placed in parallel with another 8 ohm speaker the impedance is 4 ohms, placed in series the it is 16 ohm Me I would place in parallel this mixer should handle 3 ohms

Hi. I'm fixing my Speaker there are smd transistors that are faulty, I can't see number for it to replace

Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer


If hum still persist, without the mixer connected

then speaker amp may need servicing.

Ok. First, check your power supply voltages....then check IC2 for correct voltages and also check C9 ,C17 for ESR...clip signal can come from either woofer or horn circuits...lift one end of R19 in the preamp ckt....this will break the woofer signal and see if the light goes out...if it does, look for issues with the pre-amp after it seperates the hi and low signals...if not, then look for problens in the horn circutry.....and get a schematic....it will make it so much easier....good luck....

If you read the TRUE specs on this speaker it is really a 200 Watt RMS unit. Make sure you are using balanced lines to the speaker XLR or TRS cables. The mixer should NOT be a passive mixer as these do NOT generate true balanced lines. Make sure the mic can't "hear" the speaker or you may be getting supersonic feedback that is above your hearing range that saturates the amp. If *********** can't stand to be ain a 15 foot square room with teh level you are generating, it is TOO loud for this unit to handle.

Connection all depends on what type PA system you have. Here are the rules: Power this device from the SAME receptacle your mixer is powered by, even if it means running an extension cord. Use ONLY a balanced line from the mixer... either TRS cable or XLR cable.

You can cut the treble gain some BUT most importantly is to send adequate signal to this speaker so volume level does not have to be set high when sending LINE LEVEL signals to it. Hissing noise is a product of the statistical noise that occurs in electronics. Running any device at high gain invariably brings up the hiss level. Managing thee signal levels is the responsibility of the sound engineer.

ALSO feed ALL interconnected equipment from the same receptacle or power source, even if it means running a power cable to a mixer alongside the snake. ALWAYS USE BALANCED audio cables whenever possible.

Generally speaking you should only send low frequencies to subs. The highs, while lower in power than the lows, will over time harm the voice coils. The ideal way to do this is to use an external crossover netween the main output and the amp input with the higher range going to a general set of speakers. Send the lows through the second channel of the amp and then to the subs.

In short, while not recommended, yes you can hook them up in parallel.

Assuming they are ALL mains and not for monitors connect this way:

Connect the passive to the A and B powered outputs. Please read my tip on Fixya regarding hazard of grounding speaker leads on channel A of PMP mixers.

Connect each pair of active speakers to the Main L and R 1/4 inch jacks using TRS balanced cables. Power these speakers from the SAME receptacle or source, even if it means running an extension cord to your mixer from where the actives are plugged in. FAILURE to do this creates a hazard of ground loops and ground bounce that can damage equipment. The Main L and R 1/4 inch jackls can drive more than one active speaker... these are line level signals. Make sure to use TRS balanced cables for this.

Please read a tip I just posted regarding a hazard of the Speakon to 1/4 inch cables when used with these PMP mixers.

If you are using your main speakers as stereo, then you will need either powered monitor speakers OR an additional seperate amp for them. The mon outputs on the mixer are LINE LEVEL and are not driven by a power amp. Use TRS (balanced) interconnect cables from these to POWERED monitor speakers.

You can parallel your two mains providing the parallel impedance is 4 ohms or greater (two 8 ohms in parallel at most). The the monitor speakers can be paralleled and the switch set to Main/Mon so that one side of the power amp drives the mains and the other drives the monitors.

To prevent damage to the mixer, make sure all speaker leads are secure before powering the system. Run the speaker leads through the handles of the speakers to prevent inadvertent unplugging due to personell tripping over cables.

DO NOT use the bridge mode in your use.
