Preamp + power amp club?

Does anyone know how the new ART Pro Channel II compares to this old "Tube Channel"?

I am assuming you mean the old 1 RU Tube Channel model #259 vs. the 2 RU Pro Channel II. The Pro has many features the #259 doesn't have, most notably an adjustable HPF, bandwidth selectors (narrow/wide) on parametric EQ, more compressor controls, and a nice front panel instrument input.

It is bigger and heavier.

Demeter HPB1 with Crown XTI - 2002 bridged into various cabs. It's shown with a Fearless F110.

Eden navigator and qsc pl236.(have 2 navigators because I like them so much). Also....the amp isn't lopsided....that was me kneeling on my bad knee and almost falling over while taking the picture. Lol

Used the Demeter 400 as a preamp into the Quilter BB800 and it was fantastic.

I'm using the Aguilar tone hammer on my pedal board for my preamp needs. Barring the Demeter pre, how do you like the genzler/quilter combination? Do you still get those room filling lows everyone raves on the arrays about? Any cons? I'm very interested in that exact speaker /amp set up.

Have you tried Duralane to “grease” up the knee a bit?

I bought a Demeter HPB-1 and a QSC-PLX 2402 in a rack with a tone works tuner about a year ago and love it. Plugged into a Berg HT 322.

So crest prolite users, a few questions. I have a 3.0 non dsp. It has two inputs. I noticed that when in parallel mode with one preamp plugged into the A input, both channels seem to get power as indicated by the signal led lighting up both channels on the front display. Now i completed my second fearful 12/6 and decided why not try stereo mode. I thought that would also power channel b, but i guess it doesnt. Channel a worked with the two cabs daisy chained. Do i need to use a second preamp into input b to get power to channel b to use both cabs plugged into both channels in stereo? If that makes any sense

I believe you can use a single to dual splitter (xlr or 1/4", whatever you use) to send the signal to both channels. That's how used to run my Crown in stereo. Amazon.com: Hosa YXM-121 XLR3F to Dual XLR3M Y Cable, 6 inch: Musical Instruments

Stereo Mode needs an input in both channels. Parallel mode (or Input Y) is your best bet. That signal will be sent to both outputs. All is needed is a single input. Plug your second cabinet in the second output. You will have individual volume control over each cab. You would use a Y cable if the amp didn't have Parallel mode.

This is correct. I run the 3.0 into two 4 ohm Berg cabs in parallel mode with one input from a Demeter VTBP-201. Works as advertised.

This is one of the reasons I chose the Crest. No Y cable needed. Just use parallel mode.

@Dave Hill has a new toy. Gonna hang sometime very soon. Drink some beer, push buttons, turn knobs & switch cables for him while he compares the three.
Kinda sounds kinky doesn't it. Ha!

So stereo ouput needs stereo input, makes sense. What does the "stereo" mode change when switched from parallel, just individual channel volume control?

The lows are there. There is a certain tight sweetness with this set up while keeping the fullness. The quilter and the arrays on their own are pretty good though..no loss in bottom fullness at all..do recommend.

Do you run the PLX bridged?

I no longer do that. My main (and only) cabinet for gigs that warrant this thing is a 4 ohm Aguilar GS212.

I did run the PLX bridged for a while and got tired of replacing speakers.
Now I just use 1 channel - 600 watts is more than enough for my needs.

Not exactly.

If you use stereo mode, and only connect an input to channel A, then only channel A will need a speaker. Channel B will not and can not be used as it has no input.

Parallel mode uses both sides (A & B channels) and drives them with the same single input. Naturally, you will need a cabinet for each channel.

Parallel mode is just a way to send a single input to both channels. Stereo mode requires a separate input for each channel. In stereo mode, it is possible to drive your bass cab with one channel, and then run say a keyboard or vocal monitor from the PA mixer, i.e., anything, at the appropriate input voltage level through the second channel to another suitable, perhaps very different, type cabinet.

Bridge mode adds both channels together into a single output.

Just be sure your Crossover Mode switch is in the Full Range position.

Likewise, but on an Ashdown 610 - it kills!

ESP LTD B-5E into Radial Bones ABY with each output into its own Sansamp RBI preamp

Each RBI into its own channel of a DBX266x compressor gate

Each channel of the DBX into its own channel of the Crown XLS1000

Each channel of the Crown to half of a home built 610 cabinet with angled bottom speakers.

 

[Das Jugghead]

Switched out the compressor noise gate with a a two channel EQ to try and tame down some hiss that has me tearing my hair out

Sansamp causing hiss?
