I've also checked and adjusted the head (hight/tilt and Tangency) |

With checking azimuth (also by reading hardest output of 8 channels summed to one channel) I noticed not so much difference in volume on the db meter. Is this common ? |

Are there portable machines with more bandwidth, like 16 track 1 inch ? |

All is set now. But I was wondering when checking for Rep EQ setting, I saw that the company that serviced the machine a half year ago setted the levels at 12,5 Khz to 1 DB exactly. Maybe they did this to achieve more high frequencies, is this good ? The manual tells me it has to be set to 0db. |

Hey Josh, I don't exactly understand that. - If set 2.5 db down at 10k and 1.5 db at 100hz, you have more low end... ? Or do you mean 2.5 db over the 0 db with 10 khz ? - Setting voor Repro, how does that effect Recording ? |

Han, more difficult in my opinion is only you have to record and then playback to tweak with record levels and eq. |

Narrow-format machines offer little in the way of Record EQ adjustment, and there is no low-frequency playback compensation for worn heads. One trick I’ve used is to note the level of the nastiest low-frequency head bump, then set the 10kHz Playback EQ (from the test tape) to that level. It is cheating, but only enough to minimize mistracking of the noise reduction system–dbx noise reduction multiplies low-frequency errors by 2, so a 1.5dB bump becomes a 3dB bump. Back in the day when I aligned many a Fostex E-16, the extra work of adjusting the bias by the PAR method paid off because channel-to-channel frequency response and phase were more accurate. The difficulty with most Fostex machines is that the bias adjustment is a continuously variable cap. Without a 'scope or a meter, it is easy to misalign one of these machines. By being meticulous about the bias adjustment on all machines, you may discover track-to-track anomalies that could either be caused by aging components or a head near the end of its life. The last narrow-format tip concerns tape thickness. Many of these machines perform better with 1-mil tape rather than 1.5-il tape. Unfortunately, it's not so easy to find Ampex/Quantegy 457 or 3M 227 tapes these days; however, Quantegy 407 is still manufactured. |

It's is a Fostex G16, nice machine for a 16 track 1/2 inch. Are there portable machines with more bandwidth, like 16 track 1 inch ? (I do almost all the time location work) When checking levels I was setting the erase head That's why the levels didn't change very much All is set now. But I was wondering when checking for Rep EQ setting, I saw that the company that serviced the machine a half year ago setted the levels at 12,5 Khz to 1 DB exactly.
