I was checking the Block diagram of the Rumble V3 because I was wondering what the difference is between the FX send and the line out.

I'm no engineer in anyway but am I correct when I think the line out flow goes like this:
FX send + FX return -> 2nd order HPF -> delta-comp limiter -> speaker cab sim -> line out?

Does anyone know what the cirkel with + symbol means?
I was assuming just a connection between 3 signals.

Quick update - ordered a Rumble 40 today, as discussed the other day!

Will arrive early next week, so I will post back a little report then.

Bought mainly to use as a practice amp, but also as a small gigging amp - I intend to get involved in a 'quieter' project in the near future, so from what I've read, this would be ideal.

I adore my 500/115 set-up, and this has convinced me to go further down the Rumble road!

Right, the FX send is a pre-amped signal while the XLR out is filtered, compressed, and run through a speaker cabinet simulation circuit. It's interesting (to me anyway) that the headphones out also has the cab sim. I agree with you that the circle + is a conjunction joint.

Does anyone have the technical chops to post the Rumble 500 block diagram, and be willing to do it?

WOOT! I want one also, and thought about trading in my 25. My closest GC is about 115 miles east of me in Richmond. So about $30 gas round trip in my Jeep just to get $40 or so trade in Dumb Need to make a local sale. Then order from Sweetwater. Free shipping plus NO sales tax.

Yes, there are 2 speaker cab sims in the diagram, I was wondering why the signal to the headphones out is not going through the HPF, limiter and speaker cab sim but is taken off before to a (2nd?) speaker cab sim.

Referring to the gain structure post, I also found it interesting and surprising that the master volume control is much closer after the gain control than I expected.
Just the vintage and overdrive are in between. I was expecting the master control to be just before (or part of) the power amp.
It does explain why the gain level effects the vintage and overdrive sound.

Edit: now I also understand why Fender suggests using outboard effects with the FX loop instead of putting them between the bass and the input. Then any noise would be boosted through both the gain and volume control.

Do you mean just posting the picture, like this:

No problem

What would happen if I were to connect a Rumble500(combo) to a mixing cable using a Jack from the Speaker Out instead of using the DI out?

I just received a 'heads up' on other bad things that could happen.
The External Speaker jack on Rumble 200/500 must NOT be connected to any other grounded equipment and ONLY to a speaker cabinet. This applies to the Head model speaker jacks also. Connecting the sleeve to ground (earth or chassis) may damage the power amplifier module.

At the bottom right of page 4 in the owner's manual states:
IMPORTANT NOTE: Rumble 200/500 amplifiers include a digital power
amplifier that operates in bridge mode. Both the tip (+) and sleeve (–)
have voltage present, so never ground either the tip (+) or sleeve (–) of the
speaker cable. Always make connections with the power turned off, and
use care when making connections with cables that have non-insulated
(bare metal) type plugs. Using speaker cables with insulated bodies is
preferred, but not required.

Does anyone know what the cirkel with + symbol means?

Usually that symbol means the positive pole of a battery:

but I have also seen it used on occasion as the positive power bus.
Sort of the opposite of Chassis Ground:

Basic unions do not have any actual symbol.
SOMETIMES a simple solid dot is used to signify a connection but, in general, if the lines in the drawing touch, they're electrically connected.

New member - my first post on Talk Bass ("handle" is my initials).

In the diagram posted above, junctions are indeed specified with simple dots, and ground is the second symbol in Scott's post above. Speakers in lower right are for 200/500 combo/head configurations.

Why is my first TB post in Rumble Club? I couldn't find a good Bass sound in my Peavey Vyper 100. Tried the Rumble 200 Combo and loved it! Then I discovered TB and decided I'd have more options with a head and cabinet(s), so I returned the Rumble 200 and ordered the Rumble 500 head (arrived last Tuesday) along with a 410 cabinet (should arrive tomorrow). Figured I'd like a smaller/portable amp for taking into the office, etc., so picked up the Rumble 40 yesterday - wanted to be able to use the same features on both. I'll take a number after all gets here and I can get a picture up....

You guys gave me GAS, bad!

Best regards,

Pffft! You can have a number NOW! Welcome to the Fender Rumble Club, WRM
You are member #485

Rumbles Rock!

I can't speak about the 500 or the cab you ordered, but you're gonna love that 40. If I were a betting man, I'd bet that you'll use it for more than just practice!

You guys gave me GAS, bad!

Glad we could be of service!!

back in the club again with a Rumble 100 combo. Had a 500 head last year that I sold to buy other gear. Premier gig yesterday at a wedding with my trio using my fretless 5-string Rob Allen. Really Good for that kind of money, although not able to simulate upright bass sound as good as The pjb superflight combo I once had.

 

[Neon Blues]

Little help gang! I've never had any really powerful amps before. Nothing over a M6 Carbine years ago.

Here's my question. I run my favourite cabs ever, V2 Rumble 112 and 2x8 and I currently had a 350w Rumble Head and a Mark Bass TTE500 which are great.

However, as a sucker for a good deal. I've been offered an Aguilar DB750 for a great price but I am a bit sceptical that I might damage the speakers with the extra 250Ws. I don't really ever crank my amp. Even at a gig, I am very unlikely to take it past 4-5 on the Master Volume.

Will I do the speaker's any harm?

Thanks in advance!

 

[rodl2005]

Yo will if you crank the volume or bass eq hard. Use yr ears and you'll be good to go.

 

[Muddslide]

Am I the only one here with a 150?

 

[Linnin]

Am I the only one here with a 150?

Hardly. There are quite a few Rumble Club members that own them. Members do come and go as they please just like TalkBass as a whole. If you have any questions just ask away.

 

[Linnin]

Will I do the speaker's any harm?

I suspect that you will soon find out!

I've been playing through a Rumble 500v3 for the better part of a year, and have been nothing but happy with it's combination of terrific sound and portability. I was in a music store recently and by chance picked up a Rumble 100v3 combo. I couldn't believe how light it was. I figured that 100v3's sound would be equally light. Poor assumption. The tone belied it's lack of heft. Great sound through the 1x12. Long story short, I now own a second Rumble. The 100 combo is the answer to a question I had yet to ask. I love to engage in serendipity.

The 100 is a great amp. It is my go-to amp in most situations unless I need more power and room-filling-goodness. Then I use the 200. I can't imagine ever needing more power than my 200 and I'm confident you feel the same about your 500. Good choice on the 100. It also serves as a great backup amp to have with you even though the Rumbles are solidly dependable.
