Hi all, A friend of mine just acquired an Ampex atr-700 reel to reel tape machine. He got it from the company he works for while they were cleaning out some old gear. We wanted to try doing transfers of some digital material to tape to see how it sounded. The material in question is 24bit 48k two track material that I have on my audio computer. Here's the problem. First of all we don't have the manual. We both have some experience loading tape and using tape machines so we were able to load some 1/4 tape and get it to playback. We loaded a tape with pre-recorded speech and it sounded good. Levels sounded good, the whole nine yards. Next, we plugged a mic into the rear input and I spoke into it and it sounded fine, not distorted and the record levels looked good without using much gain. It was set on mic input. Recorded some speech and it was super low on playback. Then we tried running a line input (+4db) and it choked again. Couldn't get a usable level. The record and channel gains were cranked and you could barley hear the audio, meters weren't moving at all. The rear switch was set to line, and everything else I could think of was set in place. I use an aardvark q10 for an interface and I was using a pair of analog outputs to send the signal (1/4 trs to male xlr). I checked the level of the aardvark outputs through my amp and it sounded fine. Could I be missing something here? Maybe we just got a busted unit, which is entirely possible considering it age. I looked around for a manual but most sites I dug up with information wanted to charge you $30 or more for a photocopied manual. Any help would be appreciated. If you need more info just let me know. Thanks.
