VSX-26 setup

Postby dlbnh » Sun Jan 20, 2013 2:14 pm

Hi Everyone,
I am new to a recent VSX-26 and could use some staring points for our system.
2 powered RCF HD-12A's over 2 JBL Mpro 1-18 Subs powered with QSC 3602
I am still a bit lost on the device control yet but I learn fast.
Thanks in advance,
Darrell

Hi Darrell,
Welcome to the forums.
The first question is are you going to tri-amp or bi-amp this systerm?
Do the HD-12As have the capability to accept two discrete inputs?

Cheers,
Steve

It will be bi-amp. the RCF's are internally crossed over and no discrete access.

I'm sorry, I forgot to ask if you are going to run a mono or stereo system....

Okay, there are two ways to build a VSX preset:
- using a reference microphone and a Fast Fourier based software program like SMAARTLive, you can best pick which crossover point and filters are going to give you the smoothest transition from the subs to the tops. Peavey has made the presets for their speakers but has not branched out to other cabinets.
- find an existing preset and modify it until you like what you hear.

JBL should have some information on what they recommend for low freq cutoff and filter. Getting the subs to the top smoothly is going to be another story unless you measure it yourself.

There is another option, and I do not recommend it often:
See if dBx has a preset already made for the DriveRack for your speakers. If so, I would return the VSX-26 and get a DriveRack and use the preset.

Cheers,
Steve

You evidently have two Subwoofers and two Mid/Hi (passive).

Preset:\\

Input A Left
Input B Right

Outpuit 1 Left Sub
Output 2 Left Mid High
Outpuit 3 Right Sub
Output 2 Right Mid High

Program for Outputs 1 & 3
X-Over

Low Cut at 38 Hz with L/K 24 (Linkwitz Riley twenty four dB perr High Paqss Octave Filter)

High Cut at 100 Hz with L/K 24

Outputs 2 & 4
Low Cut 100 Hz with L/K 24


Experiment with the level of Outputs 1 & 3 to get you preference for a Sub to Mid/High balance, as there may be differences in loudspeaker sensitiaties and a 40 to 100 Hz bandpass drops the total energy under the curve, uh that would be a reduction in bandpass level.

The mid/highs are powered RCF-HD12's

Copy that.

What Marty gave you is a starting point for the VSX-26, sending 38 to 100HZ to the subs, and the rest to the tops.

Considering that you are talking about the wiring on the back of the output panel in your equipment rack, 14AWG is very adequate since the length should not be more than a few feet.
