What type of footswitch works to turn on/off digital delay on Harbinger HA 120 PA? tried momentary per manual, didn't work; on/off click footswitch also did not work


We sell this Same PA at the music store I work at,
and I know that Any normally open momentary switch will work
if it's Not working, then either the switch or cord is defective
or we have had to service a few of these, never for that problem tho? So I guess it could be the input jack on the PA ?
Hope that Helps?

No sound coming out of my mackie


Whether you are experienced in electronics repair?
if not, try this simply way:
1: Test whether the power amplifier is still working. See figure 1.
Power OFF,adjust the EQ settings as shown in the picture.
Minimize LEVEL.Switch ON Power. Touch pin 3 at the INPUT socket by using a small screwdriver or piece of wire / cable.
Slowly raise the LEVEL,a little bit only (as the clock showed 7-8) until
sound is heard in speaker. If not heard, slowly raise again LEVEL.
If audio input signal is heard,it can simply be taken to mean
that the amplifier is working.
If LEVEL at 9 o'clock position,and the audio is not heard,
the possibility of the amplifier is damaged.
Switch OFF the power. Take it to a repair place.

2: When the Power LED is lit, but no sound,
There are many possible causes, one of which is:
I have been getting 3 times similar cases, and all are caused by
two Rectifier-Diode (either or both.) damage on the power-supply-unit.
Remove/desolder,measure, if damaged replace it with a new one.
See figure 2-3.

Can I hook up a monitor to a Harbinger HA120 Portable PA System


Yes you can,you will need 2 run ,1\4 in 2 jack 1\4 in imput too the mic\line imput your chaing your signal so you will need too preset vol levels on the 120 too your desired max peak out put buy first putting you output slide too max on your mixer (running a signal from a cd player or other divice into mixer)then turn vol up 2 disered max loudness you want to run sound at then lower the vol using out put from main power slide on your mixer. Its called chaining your componets .better way of hooking up a band on a small system.ywc Rev bob dj 25yrs exp

HOW TO WIRE GEMINI GRAPHIC EQ 3000 TO behringer djx750 proffessional MIXER


Line level output of the mixer would go into the line level inputs of the EQ, and the EQ line level outpputs to the line level inputs of the amplifier. If you are faced with a mix of unbalanced inputs or outputs, to balanced inputs or outputs it gets a little complicated because you need to matrix the balanced signal to unbalanced load and vice versa. There is no single answer to doing this either.

RCA jacks are unbalanced, 2 conductor 1/4 inch connections are unbalanced most of the time. XLR and 3 conductor 1/4 inch jacks and plugs can be either balanced or unbalanced.If either are wired so left and right are a single ring or tip on the 3 conductor 1/4 inch jack, it is unbalanced and they would share a common ground lead. XLR wired with one pin common with shield and right and left have a single conductor on the plug or jack, that is unbalanced.

Hooking up the speaker to an amp, using the rca line out of the amp i have no volume control from the amp knobs, can i hook the speakers up to the amp from the speaker out ?


You should NOT under any circumstances connect an audio input lead to a speaker output jack!
The RCA jacks you are trying to take output from ore "pre fader" which would be solid "line level" and not controlled by volume controls. Tap off the INPUT to the amp... you should be using balanced lines for the interconnects. RCA jacks are unbalanced lines. You can drive several inputs from a line level output of a mixer for example using a splitter cable.

Im trying to connect a peavey kb300 with a mackie micro series 1402-VLZ 14 channel mic/line mixer


The mixer is stereo and the amp is mono. The line level out of the mixer MAY overwhelm the KB2 regular inputs so try running the mixer into the PA input jack.

Ran too much power through the speakers and I think I fried the crossovers. Can the crossover be replaced?


This makes little sense... these are bi-amped speakers meaning the crossover is an electronic LOW LEVEL filter network. You can send LINE LEVEL signals to these (never the output of a power amplifier) and not damage the crossover electronics. You would normally connect the balanced line-level output of a mixer into these.

If you have connected a power amp into this by mistake, you likely blew the input circuit. You will have to have the circuitry replaced.

Very important is to connect ALL interconnected equipment to the same power source or receptacle. Powering speakers from one end of a venue and the mixer from the other end wall receptacles is a good way to blow circuitry due to ground bounce in buildings.

Give us more information of how you connected this AND also the symptoms... unless you are into electronics, self diagnosis of the problem may lead you astray as well as the technicians who fix it.

Hi have been given a Marshall MBB15 amp to find out why it doesnt produce sound through the input jack, have checked inside, looks like the resistors connected directly to the input jack are dead. Could...


Dead resistors? The evidence would be if the resistors are cracked OR if their is evidence of smoke/fire around them.

In either case, there would LIKELY be damage at least one or two layers deep beyond those resistors if in fact they are fried. If they are cracked physically, teh circuit board also may be cracked due to physical bending. Tripping over an inpout cable can do this.

Causes of this would be shorting the input to power line voltage or the output of a high powered amplifier.

I question that the resistors are "dead".

THE USUAL cause of failures of these small amplifiers is frying of the output power chip which is often in the TDA family of 5/7 terminal amplifier chips in modified TO220 packages.

Another less common problem is failure of the rectifier and filter capacitor combination.
