Using the FLAT mode with the VOICING FRFR, OF RAW or LF FLAT on the POWERCAB 112 PLUS

Recommended Posts

Hello,
1. I use a full AMP MODEL, a CAB MODEL and a MICROPHONE in the POD.
2. I connect to the POWERCAB 112 PLUS through the L6 LINK ports of both units.
3. I use the FLAT mode on the POWERCAB 112 PLUS.
4. I understand that the use of any of the VOICING (FRFR, LF RAW, LF FLAT) does not imply that you are no longer using the FLAT flat response mode, otherwise it would change to SPEAKER or USER IR mode..
5. The use of FLAT mode with VOICING FRFR on the POWERCAB is quite disappointing using a full AMP MODEL, a CAB MODEL and a MICROPHONE on the POD.
6. Using the FLAT mode with the VOICING LF RAW or LF FLAT on the POWERCAB 112 PLUS while using a full AMP MODEL, a CAB MODEL and a MICROPHONE on the POD sounds much better
7. Is my POWERCAB really amplifying what happens in the POD or is it modifying the POD simulator?
8. I don't really understand VOICING in FLAT mode. If I use LF SOLO mode or LF FLAT mode, does it imply that I am not using FLAT mode? If so, why are the SPEAKER mode and the USER IR mode?

Thanks for your reply

Powercab x12+ has three modes

 

Flat Mode - has three voicings that select the final post-processing EQ and crossover settings for the speaker system. XLR out is the same as the Powercab input (for all voicings)

  • FRFR - Uses the high-frequency compression driver with a flattened frequency-response EQ for full-range operation. The tweeter is on, XLR out is the same as the Powercab input. Use when cab or IR models are provided before the Powercab input.Good for acoustic instruments.
  • LF Raw - Uses only the woofer with no EQ applied, allowing Powercab to be utilized like a typical 12" guitar speaker. Tweeter is off. Use with no IR or cab processing at the input.
  • LF Flat - Uses only the woofer with a flattened frequency response EQ. This voicing is used as the normalized basis for the Speaker models. Essentially each Speaker model is an EQ added to LF Flat that reproduces the sound of the modeled speaker. Tweeter is off. Use this for a different guitar speaker sound. 

Speaker - each speaker model adds EQ to to the to the LF Flat basis to reproduce the sound of the speaker model. XLR output is a cab model that matches the speaker model, and includes a mic model. Tweeter is always off. This is probably the mode that leverages the unique features of Powercab the most to provide the amp in the room sound. It is actually a guitar speaker in the room with no mic model. Use with no IR or cab processing at the input.

 

IR - uses IRs on the Flat/FRFR voicing for additional speaker selections. XLR output includes the IR processing. The tweeter is always on. Use with no IR or cab processing at the input.

Gracias. No acabo de entender que son los IR. Tampoco se como cargarlos en el PC+

What I find very confusing is that, despite the fact that the FRFR mode uses the high frequency driver, it sounds dark, muffled and lifeless compared to LF Raw or LF Flat, neither of which uses the HF driver.  I can certainly dial in a nice tone using LF Raw or LF Flat, but the problem I see is that I'm hearing something nice on stage, and presumably I'm sending something dull and lifeless to FOH (as the PC+ is just passing through the input from the modeler).  

 

What setting is a good approximate of a full-range PA speaker? FRFR?  And if so, why does it sound so dark?

Exact. I do not understand that using all the amplifier and cabinet simulations in the POD and sending the output L6 to the Powercab (and configured this in FRFR) the result is not good. If I use LF voicings, it is good voicings with POD simulations. I speak of distorted sounds

POD doesn't have impulse responses or high cut in the cab models if I remember right. That's probably your problem. You're using the speaker to tame the highs instead of a high cut. 

 

Try Flat FRFR mode, but turn down the tweeter in Powercab global settings.

If I use a POD preset with distortion (either with CAB or without CAB and with AMP or PREAMP) and I use a speaker model in the Powercab the tweeter still sounds and the sound is disappointing. When using a speaker model, shouldn't the tweeter automatically turn off?
I appreciate any help in advance as I begin to think if it will not be defective.

In Global Settings, I select HF TRIM and leave it Off but I don't notice any changes.
I'm desperate

I think that the HF tweeter is not active in PC speaker mode.

On way i found to modify the sound in this mode, is to go in the speaker parameter list (click on led button and go downside) select and adjust the high/low cut in each model as you like...

I just want to say "Thank You" for this thread!!

 

I was wondering why the '000 Flat' patch on my Powercab 112+ sounded anything but flat.  

 

Reason (as per posts above):  the subsetting in the patch was not FRFR  (it was one of the LF modes) and so the tweeter was not on.   Doh!

 

I had let this slide for awhile as I was loving all the other "speaker" sounds.  However, one of my important applications does require an actual flat (FRFR) response, and I was really starting to wonder if the (my?)  Powercab could deliver.

 

This thread solved it for me.    Many thanks!
