    Soundcraft Ghost + TSR-8 (and +4dbu Outboard Gear)

    Sign in to disable this ad
    Hey Guys... So I'm not exactly sure where this should go...

    After the rather traumatic experience of purchasing a completely useless M-520 to go with my TSR-8, I settled on a Soundcraft Ghost 24 (not LE). I'm super happy with this mixer (although I really miss the M-312b I traded for the M-520).

    I've tried searching about this on multiple forums, but I can't seem to find anything - most people interface these with a DAW setup, so that doesn't really help. The manual says that the board has the ability to change the tape inputs and group (buss) outputs from +4dbu (stock) to -10dbv. Has anyone successfully done this? Do you think this would cause problems if, say, 8 of the tape ins and the group outputs were -10dbv and the rest of the board was set to +4dbu?

    Say I want to run an AUX send to a reverb unit or something, since the AUX outputs (and all of the other outputs) are +4dbu, will this boost the -10dbv level of the tape return? Or will it just keep the same level? Also, if I make this change, how will that effect the mixdown? I am going to a Tascam 32 right now... Will I just have to really watch the levels (and crank the gain if I'm monitoring off this machine)?

    I'm still trying to wrap my head around incorporating new +4dbu equipment. I used to run a completely -10dbv setup (it was awesome), and I never had to think about levels getting all messed up between gear. I posted about this in The Rack, but my situation has changed completely... would it be better to get just get a Fostex 5030 and keep the board at +4dbu? Any help would be greatly appreciated!

    If there are separate switches/jumpers for the group outs and tape returns to switch over to -10db, I can't see how that would affect the aux and effect sends levels or those +4 db levels affecting the tape returns and group sends as those are all independent signal paths. You should be fine and not need any outboard level matching units.

    Cheers!

    It's a long time since I've used a Ghost but they're lovely boards!

    From memory, although it's possible to change the default level of the Tape Returns on each channel by unsoldering a resistor, this is not normally necessary because the Tape Return level control has a sufficient range to cope with either -10 or +4. It's something like +/- 15dB from memory.

    In other areas, the change of default level is by simply adding/removing a link--easy to do if you're careful. Just take the bottom cover off the mixer and follow the instructions. I've just had a look and the owners manual with all these details is available HERE.

    All the board I/O can be switched from -10dB to +4dB or just the buss out/tape returns? Do the aux send/returns stay at +4?

    Either way, I'm with Ghost, I don't see how or why it would matter. As the TSR-8 is -10, I think you'd be better off running the necessary board ins/outs that its going to connect to at -10 instead of adding another piece of gear in between. Why don't you just pencil out your basic setup, and determine if any connections are permanent (e.g. the buss outs to the TSR-8) and set those at the appropriate level. It sounds like most of your gear will be at -10 and a handful of sexy bits at +4 so I don't see why you couldn't make semi permanent connections and just label well and pay attention when re-patching.

    It's a "pro"sumer spec for line level signals...-10 is consumer, +4 is line....

    Nope. Completely wrong. Both -10dBV and +4dBu are forms of Line level. The -10dB version is typically used on consumer gear with unbalanced inputs and outputs; the +4dBu level is standard on professional gear with balanced ins and outs.

    Mic level is more like -50 to -60 dB.

    Edited to add: I see you've amended your post while I was typing a reply based on your mis-information. Even though you've corrected the glaring clanger, your post is still a bit confusing and not overly useful to the OP who clearly understands the difference and is asking about mixing and matching the levels.

    I started typing then the phone rang. I'm sorry I have a semblance of life outside the forum.

    Strange mistake to make in the first place though...

    Indeed, there are 4 other prosumer, consumer threads going on right now. Why is there no stickied Line level posts....Seem to be a fundamental flaw in forum. I like the personal attack though, classy. Guess with 14mil rep you can do what you please.

    The rep points are meaningless. You are not being abused, just corrected.
