one more thing. did you calibrated playback levels in repro and sync with just the meter connected ? or also the XLRs? the repro levels have to be adjusted only with the meter connected, nothing else, if you had the XLR outputs connected, you may have loaded the circuit and the whole procedure...

disconnect the XLRs, leave only the RCAs. Reason is that the load on the circuit (impedance) is higher or lower when you do that.

1. with the recorder in stop mode and input mode, you should see the 10k signal in the VU meter at "0 db" just before the red. 2. Switch to repro - the VU meter goes down like no signal is in, because you are now monitoring the repro head, not the input. 3. Press REC/PLAY and you should see...

great. how did you fixe it in the end ?

also you should make sure that there is no gumming on the solenoid. Probably a good idea to clean up and lube as well.

is there a link somewhere to look at these schematics ? also, did you used de-oxit on all potentiometers to clean them up ?

if the parts are magnetized, you will get dull frequency response mostly. Random noises like crackling are not because of magnetization.

if it is present on all channels. it has to be related to a common component. The power supply may have a different load when in input mode or play mode. Do the following tests to check if the noise is present on the following scenarios: 1. Put it in input mode, but with the reels moving -...

yes you can. but measure the output level first with your RMS meter. To see if the 0db in the console is -10 in the green scale. What matters here is that you know what the reference level is. However as you already calibrated the inputs on the recorder. You can simply move the fader...

try putting the machine on PLAY and monitor the input. The noise may happen only when there is more load on the power supply, like when the motors are running for example. See if the noise is in there. Is the noise present in all 8 channels or only in some ? you may think that the unit is...

not the heads. Your problem is in the repro circuit. It can be a physical unstable connection, like a connector or solder in the PCB. anything in the circuit path. Does it happen in all channels ? or only on certain ones ? if in all, it is something that is common to all channels, like...

Don't worry about the peaks. Ignore that for now. The jumper is normal it is on all the cards. Manufacturing issue, most of MS16s and Tascam 58s (same card) have it. Now, time for the calibration tape.

The generator output level is too high. The generator has two controls one is for frequency, the other is output level. First connect the generator directly to the millivoltmeter and make sure it says -10 on the green scale with the know set to "1". After that connect it to te recorder...

the link that i sent you, explains how to calculate the period and the frequency. It even has a quiz on it at the end and shows you how to calculate it properly. The wavelength in this case, you can consider it to be the same as the period. So don't get confused by terms. The scope will...

the scope is enough. If you go through the training link, you should be able to learn it. What questions you have ?

check this out, it will give you some basics: Oscilloscope Frequency Measurements if the meter says -12, increase the level on the generator so it says -10 (on the green scale)

1. Use the sine wave output, not square 2. The RMS meter will only show you the level, not the frequency 3. The keys below the left dial are the multiplier keys. So, for 1khz, put the dial in 10 and the multiplier in 100x 4. Check the signal with the scope and measure the period, (google how...

yes. for input use the generator. Oh man, you are so lucky.

yes that is the "1" that i mean. Yes follow the manual sequence. Yes with the -10 exception. Otherwise you need the XLR connections to do it. How much did you pay for the W&F meter?
