I need some help connecting and using my Master Room Reverb to my Tascam M208 mixer.

If you want to use it as a stereo reverb...hook its the outputs to the EFF RETURN 1 & 2 (L & R) of the mixer....though I don't see a pair of SENDS from the mixer, just the one that says EFF, so your SEND might only be mono...which is OK, the Reverb unit will still "manufacture" a stereo reverb sound.
...but there are three other outputs there, L, R and FLB that might be used...???

Put up a close-up picture of the top of the mixer so we can see the knobs of at least one channel and the master section.

The usual method of hooking up one Reverb unit so it is available to all channels, is via the AUX/SENDS and the EFF RETURN. That way, you set one global Reverb sound, and using the AUX volume for each channel, you send a desired amount of signal to the Reverb.
 
Looks like the Foldback (FLB) send can be used same as the EFF send...so that means you can feed both Left and Right sides of the Reverb unit with each of those.

Basically...treat those two knobs as your AUX1 and AUX2 sends...there doesn't aapear toi be any difference between them.
Now, even though the reverb unit is coming back in stereo, you DON'T have send from both AUX1 & 2 for every channel.
IOW...you have electric guitar on CH1 use AUX1 to send to the reverb unit. Then you have acoustic guitar on CH2 use AUX2 to send to the reverb unit.
You CAN use AUX1 as your send for everything...BUT...it really depends how your reverb unit processes the L/R inputs.
Does it do its own mixing internally to give a stereo output regardless if you just send to L or R input...?
Or...does it need a L/R stereo input to give you a L/R stereo output.
Every box is different.

Now let's assume the reverb does its own summing and creates a L/R stereo output even with one input. So ten you might ask, why not just use AUX1 for all your sends....???...because you don't want to overload the one AUX bus.
So I usually split between two for a given stereo processor.
Though also some FX units might behave differently at their stereo outputs depending if they get a single input either on the L or the R channel.
IOW...the stereo output might sound a bit different for each single input....check it out.
That's why I like to use two AUX sends per stereo FX unit.

Of course...with only two AUX sends and only a stereo FX return you may want to split things up if you have more than one FX unit, though you will then have to find a way to submix both units for the single stereo input/return...OR...you can use a spare channel(s) for other FX returns if you have them.

Makes sense...?
Go take two aspirin and call me in the morning. ;)
 
The reverb is stereo but can be used as mono.
I dont understand the difference between mono and stereo on my reverb unit.
If i use the stereo reverb i can have 2 different settings of reverb applied to different channels? And mono would be the same reverb setting to every channel?
 
Looks like a cool unit. I'd be interested in hearing how it sounds. Is it a spring or digital? If you use mono you just use one channel, probably left and when it's returned to your board it will be in both speakers if you pan it in the middle.

You really need the manual to know exactly how it works. With mine both signals are mixed together but then split and mixed with the dry signal L and R at the output. So it's actually mixed wet mono but the wet signal goes out both sides. You'd be able to tell if this is the case if you have a signal that's panned L coming out in the R channel. Sounds funny but it does make a stereo spread. It's good with mine because it's digital so it mixes the analog with the digital signal plus it also has stereo effects.

I can actually have one input in mine and still have stereo effects as long as I have the L and R outputs hooked up.

I second that...do you have a manual or can you get one?

I'd be lost without the manual to my Tascam RS-20B for the very issue of how it handles operating as two independent mono reverb channels or mono to stereo or stereo to stereo.

Nice lookin' reverb box BTW.

Allen, tell us how you are wanting to use the reverb box...IOW what are you wanting it to do for you and then we can hone in on figuring out how to get from where we are to that end.

NOTE: if you are planning on using the FLB or EFF output jacks to connect to the reverb unit you will need to make or buy cables that go from 1/4" TS to XLR, and you'll want to make sure that pins 1&2 of the XLR are "strapped" or connected together. -OR- you may be able to use the AUX in and AUX out jacks on the front of the unit for input and output and just use TS to TS cables, but I'm not sure if the AUX in jacks are pre or post input trims on the reverb unit...you'll have to test some of this stuff out by plugging it up and seeing were stuff goes when you hit those MONO switches...I betcha for mono to "stereo" operation you latch the left MONO switch and leave the right MONO switch unlatched...that would be if you just used the EFF send on the M-208 to one input of the reverb unit but connected both reverb unit outputs to EFF RETURN 1&2.

The out mix knobs on the reverb unit allow you to use the unit as either inline or as a send effect...IOW if you want to add reverb to a stereo mix you can take a stereo source, connect it to the reverb unit and, using the mix knobs, have the output of the reverb unit contain some direct uneffected signal as well as reverb signal and mix to taste using the output mix knobs. When using the reverb unit as a send effect you want to have both those knobs rotated fully clockwise so the reverb unit outputs 100% effected signal and no dry signal.

ALSO: miroslav is right about being able to use FLB and EFF as two separate sends so you can use the reverb unit as a stereo to stereo unit, but this is complicated because the FLB send is pre-fade, and the EFF send is post-fade. Plus if you use the FLB send for an effec send then you will have no monitor buss for cue mixes when tracking.

Good point about the pre/post fader...it's not something I would have known just from looking at the pictures of that board. :D
Yeah...manuals help with the details.

Oh...AFA the cue mix, I'm assuming he would use both FMB and EFF during his stereo mixdown...so no real need for a cue mix at that point.

Alan,
With the limited number of I/Os...you might find a patchbay to be of help...otherwise you coudl end up plugging and unplugging you gear a lot from the back of the mixer....but that's your call.
When I use to have a small TASCAM board a looooong time ago (Model 3, I think) and was using a 4-trasck and 2-track...I did a LOT of plugging/unplugging!!! :)
 
Ok well this is what i'd like to do.
I have 4 tracks i'd like to add reverb to.
track 1 = Need to record Lead vocals - NEED reverb
track 2 = Need to record Back up vocals NEED reverb
track 3 = bass, Strings (a little bit of reverb)
track 4 = rhythm gtrs, drums (tiny tiny bit of reverb)

Its a spring reverb btw.

I would add reverb after I record the vocal tracks is this correct?
I cant find a manual for my reverb. I might just upgrade my mixer to the tascam 308b.
Im not gonna use the stereo option on the reverb because I only have 1 eff. I know I cant use the FLB because I monitor what I record on that switch.
So if I only use the EFF button it would have to be mono. So how would I connect it?

Ah...right...but still messy with the pre-post issue. But, depending what's under the hood/how it sounds I'd probably be using the reverb box inline M-208 Stereo L-R out --> reverb 1&2 in --> reverb 1&2 out --> mastering deck.

It'll help to know how Allen wants use the reverb unit (i.e. if he's wanting to track wet, or if he only typically uses two of the 4 groups he could use groups 3 and 4 as a stereo effect send during tracking...not so convenient but another option...)

Yeah-yeah...sorry...I took an extended time to compose my last post and you got one up in the interim and I didn't see it.

Sounds like you just want to add reverb as a send effect during mixdown.

Just use the EFF send out jack on the M-208...try connecting that to the AUX1 input on the front of the reverb unit using a TS-TS cable. Push the left-hand MONO switch in. Rotate the reverb unit mix knobs fully clockwise to "CHAMBER". Leave the right hand MONO switch out. Connect the AUX1 output jack on the front of the reverb unit to the EFF RTN 1 jack on the M-208 using a TS-TS cable. Connect the AUX2 output jack on the front of the reverb unit to the EFF RTN 2 jack on the M-208 using a TS-TS cable. Pan the EFF RTN 1 hard left...pan the EFF RTN 2 fully right. The EFF RTN jacks pipe straight to the STEREO buss of the M-208 which should be connected to your mastering deck.

I'm making some assumptions here about the reverb unit since I've never seen one of those before and we have no manual so don't get tweaked if this doesn't work.

Also, for starters I'd rotate the INPUT level knobs on the reverb unit to 12:00, and rotate the EFF send master level knob fully counter-clockwise. Also, rotate the EFF RTN LEVEL knobs fully counter-clockwise. This gets the reverb unit set middle of the road as far as input sensitivity (since we know noting of its nominal operating level) and shuts the door on stuff going out of the mixer to the reverb unit, or coming back to the mixer from the reverb unit. Now, send some stuff on your channel strips to the EFF buss and then slowly rotate the EFF master send knob clockwise. You should start to see signal on the LED meters on the reverb unit. Now, to just listen to what is coming out of the reverb unit (i.e. 100% wet/effected signal), make sure all the ASSIGN 1-2, 3-4 switches on the mixer are up/off. This will keep anything from going to the subgroups and on to the STEREO buss, but the EFF send is still active as are the EFF RTN busses. Switch your MONitor source to ST (to monitor the stereo buss) in the monitor source switchrack on the right-hand side of the M-208 control surface, and slowly rotate the EFF RTN 1&2 knobs clockwise. You should start to hear lushious spring reverb. If you want to hear how audio is coming through the reverb unit dry (e.g. so you can tell if audio is distorting for instance due to too high levels or some other problem), rotate the output knobs of the reverb unit fully counter-clockwise to "DIRECT".

Let us know how this goes, or if I'm wrong about anything somebody flag it.
 
Thanks sweetbeats! Your instructions weren't Chinese to me!
Really appreciate it! Ill let you know how it goes.
 
Alright so i got it hooked up. I can hear the "woooooosh" of the spring i believe haha. I played with it for awhile and I have the EFF RTN 1, and 2 connected but i dont hear anything from EFF 2 I believe because I dont have an output EFF 2 on my board so nothing is connected to AUX 2 imput and from AUX 2 output i have a ts ts cable connected to EFF RTN 2. So i guess my board is only designed to have 2 MONO effects going in. Tell me though I might be wrong.
 
Also what are other ways to use my unit besides send effect during my mixdown
