Cheapest way to try and fix is, with the unit off, turn the crackling control back and forth many times. Wiper sometimes removes corrosion on the carbon strip. If this doesnt work take the knob off and dribble some deoxit d5 down the shaft and work it some more.
Hello, the failure you describe may be caused by the aging of the power supply capacitors and may have coincided with the use of the phantom and not be responsible
Hola, la falla que describes puede estar originada por envejecimiento de los capacitores de fuente de alimentacion y pudo coincidir con el uso del phanton y no ser este el responsable
As long as you watch the impedance, the unit is spec'ed with 8 ohms. The power rating of a speaker is only the speaker. You could put a 500 watt speaker, r a 20 watt speaker on a 20 watt amp, it will not make any difference. If the speakers are 8 ohms the the impedance could be range from 32 ohms or 2 ohms, depending on the arrangement.
All I can offer is a story I read about john Lennon telling a studio tech he was going to do something similar - admittedly with 1960s technology. The story goes that the technician said "No Way" it would produce too much distortion. He did it anyway and I think this is what produced some of the "fuzz bass" type sounds in a couple of reords.
Turntables output at phono level NOT line level so make sure your settings are correct to engage the phono pre-amp in the desk for the lower signal level.
Looking at the rear panel of the SA, the only way you can use the EQ is to hook the tape rec out to the EQ inputs, then the EQ outputs to the tape inputs. Then select tape monitor at the SA and your EQ will be working for you.
