Distortion & low signal

I have purchased a second-hand Fostex FD-4, set it up (normal mode) as per manual instructions. On attempting to record/monitor a guitar track the gutar signal is coming through at a) an extremely low level- LEDs only go up one or two with guitar at full volume & input/master faders up to 7/8 and b) distorted.
This has happened with both an electric and electric-acoustic guitar, I have tried swapping leads and all four input channels (including the two that have high/mid/low switches) I have tried lowering instrument volume and pretty much everything else I can think of.
The manual lacks a troubleshooting section and I've gone through the setup step by step.

    Thanks for the tip (I'll do it regardless) but I don't think its the answer: I've run a keyboard into the system (using same leads/inputs) and its fine..
    Could it be an impedance issue?

Use new connection cables with its new jacks------bring a contact cleaner spray and apply it in all of your sockets(the places where you put your jacks)and turn your system off put your jacks in sockets-----in----out many times-----then turn system on.--also apply your contact cleaner in all volume control and move it continuously.

3 monitors required for emx5016cf-- daisy chain? Any way to EQ monitors?

There are several ways to solve the problem. Probably the simplest technically is to connect a powered speaker (or separate amplifier) to one of the ST OUT jacks in the master section of the top panel for the third speaker, and connect the other two speakers directly to the speaker jacks on the back. The drawback to this arrangement is the possibility of problems with setting the frequency correction (automatic equalizer adjustment). You would have the same problem with paralleling speakers (more on this in a subsequent paragraph) on one channel. It may help to use a second speaker from each channel for the "third" monitor so the automatic EQ is working with the same setup on each channel.

Another method is to daisy chain the mixer by connecting another mixer/EQ amplifier to the pre-EQ SUB OUT jacks to drive the third speaker. This permits independent equalization and level setting for that monitor. (You would probably set this EQ first with the main outputs all the way down, then set the EQ on the two primary monitors.)

Regarding multiple speaker connections to the speaker out jacks: Do not connect them in series ("daisy chain"). Unless they are very closely matched, varying responses in the speakers may cause distortion, and each will be running at about half power. You can connect them in parallel (the + terminals are both connected to the SPEAKER jack + terminal, and the likewise the - terminals are all connected together), if the total impedance is as least 4 Ohms. Note that when two speakers are in parallel, the impedance is calculated as follows: (X1*X2)/(X1+X2), X1 is the impedance of one speaker, and X2 is the impedance of the other. In other words, parallel connection reduces the impedance, and too many in parallel will overload the amplifier. If both speakers are 8 Ohms, this works out to 4 Ohms. See page 29 of the owner's manual.

I'm a guitar player, never had to mess with the PA system. I needed to come up with a monitor system to work with a non powered mixer used for powered mains. I can't afford good powered speakers, so I...

This mixer will run 2 8 ohm cabinets per side, if this is an older unit, it has only one NL2/combo jack per channel....with the button on the front panel in the Main Monitor position you can run 2 main cabinets and 2 monitor cabinets, you will have to daisy chain your speakers.All speakers powered from the back of the unit must be passive, no powered speakers.....if you want to use this head just to run moitors and run a pair of powered mains then connect the jack on the front that says main out to input of your powered speakers, hopefully your powered speakers can be daisy chained at low level, then if you want to use the 8600 to power only monitors, get a 1/4 in y cable and plug it into monitor out on the front of the mixer and then plug it into PA 1 and PA 2 to the right there and both sides will now be the monitor mix from this mixer and it will run 2 speakers per side, as long as the cabinets are 8 ohms.

I am experiencing distortion when using my dsp1124p FB destroyer

I dont know this model of feedback destroyer, but i'd like to tell you this. I'm a service technicien for a touring company. We found that in the last 10 years Behringer quality drop down so much that was making alot of their components useless. To cure such problem usually found with monitor, i'll recommand buying a 31 band EQ and adjust the mid high freq level section. You could install it with inserts cable just on the main vocal entry i guess, also you should give a try to this way of connections for you feedback destroyer. It might be the way you're hooking it. Send a draw of the actual connections...

Can someone please explain how to link up outboard EQ/comp to my Fostex 160? Advice most appreciated! Best, Stu. I want to linkup a TL Audio 5013 EQ and a 5051 Compressor to my Fostex 160. What method...

Hiya, you will need to make up a new jack cable with a stereo jack that then leads to 2 mono jacks. The tip goes to one jack and the ring goes to the second jack. In the Fostex there are 4 SEND/RECIEVE sockets. these are the interface jacks. Plug the stero jack into one of them Then the jack that connects to the ring goes to input of the EQ, the OUT of the EQ goes to IN of the COMP and then OUT of the COMP goes back the other Jack plug connected to the tip (the grounds are common byt he way and connected together in the stereo jack). The EQ and COMP are now connected into that channel you have chosen. See pic attached

Peavey Bass Amp TKO115s

Start with a clean setting - zero cut and zero gain on the Eq. Play a song close to the amp, and then move away, playing the same notes. Do you still get the distortion? Change lower the input gain and repeat the test. Lower the output gain and repeat. Are any outboard distortion pedals in the mix, such as overdrive? Eliminate them. Run straight through from your axe to the amp. Check for any distortion settings. Set everything including reverb to zero. When the distortion disappears, this is your base setting.
Change only ONE parameter at a time. When the distortion comes back, you have found your problem.+

Get yourself a manual. It will help you. You can DOWNLOAD A FREE COPY of the PIONEER DJM600 INSTRUCTION MANUAL from HERE.

Now, you have to use the CUE button function on each channel to select what you want to hear when you cue things in the headphones. Last, you control the volume of the master cue in the headphones using the CUE volume of the headphone CUE section.

Bass frequncy

Hi there,
Although I am not familiar with the Zoom HD 8 Track I am a former sound engineer so may be able to offer some general advice.
Firstly, because the wave pattern of low frequencies is very long, there are a number of things that will greatly effect bass response caused by standing waves.
1) The position of your bass monitors. Ideally these should be low down but not directly on the floor, especially if the flooring is wooden.
2) Try your monitors/speakers at a slightly different angle. Bass can bounce off walls, back towards the sound source and phase out the signal, rather like a noise cancelling system.
3) Try listening to the sound in different areas of the room. You will be amazed at how the sound pressure level will vary, simply by you moving from one position to another.
4) Never put bass tracks exactly at centre, always offset them slighly by a few degrees left or right.
5) Do some of your mixing using headphones, you will not have to worry about standing waves. But remember that things sound very different on speakers in free space.
Strangely, the reason you are getting distortion when you turn things up is probably because your bass is on the verge of over modulation to start with. Really bass is felt, not heard. You could try is to decrease your mid and high frequencies a little. The ratio between high frequencies and low ones will then increase by default and your bass may feel heavier.
What are you mixing?
