Two Options
There are two distinctly different ways to connect effects. It is important to understand what the difference between these methods is, so you can choose the right one for your setup.
Serial
The first method is often called “serial”. All effects are connected in a chain and the signal is processed sequentially in each effects processor. Nearly all stomp boxes for guitar work that way. A typical example would be and overdrive followed by a reverb. In a serial effects hookup the order in which effects matters, e.g. it makes a big difference whether you run first through the overdrive and then the reverb or first through the reverb and then through the overdrive.
Parallel
The second method is referred to as “parallel”. This is mainly implemented in conventional mixers through the Aux or Effect Send/Return connections and controls. Here every effects processor gets the original (unprocessed) signal as an input. The output of all effects processors is then added together and summed with the original clean signal. One point of note is that in the parallel connection, there is always a component of the original signal present in the output. A typical example would be reverb and a delay which are used for vocals.
Which one should I use ?
Choosing the proper connection method depends on your application. There are some effects that MUST be hooked up in serial. Examples are an equalizer or a compressor or limiter. The parallel method mixes the original signal with the processed version and in the case of the equalizer that would generate highly undesirable interference and potential phase cancellation. It would also defeat the purpose of the compressor. Furthermore, many digital effects processors have an internal processing delay, which is applied to the signal even if no effect is applied. Mixing this delayed output with the original signal can result in unintended comb filtering.
Using serial effect connection with the Personalized Amplification System™ power stand.
To connect one or more effects serially simply use the insert jack on the power amp. You probably will need an “insert” cable that has one TRS (stereo) 1/4” connector on one side and 2 mono 1/4” connectors on the other side. These are available at your local music store or from any music instrument internet retailer such as this. The mono 1/4” plug labeled “send” or “ring” connects to the input of your effects processor and the one labeled “return” or “tip” to the output.
Using paralell effect connection with the Personalized Amplification System™ power stand.
To connect an effects processor in parallel with the original signal you can half-insert a normal 1/4" plug into the insert jack (that means insert to the first “click” but not all the way) and connect that to the input of your effects processor. The output can be returned into either Channel 3 or Channel 4 in the power stand. If you want to hook-up more than one effects processor in parallel you may need to add a small mixer to your system.
There is a workaround to avoid the "half-way" insert cable. If your handy with a soldering iron you can make a cable with one 1/4" TRS (tip ring sleeve, stereo) and one normal 1/4" (mono) plug. On the TRS end connect the tip and the ring together, then simply proceed like you would with an ordinary guitar cable (on both ends: wire shield goes to sleeve, and wire core goes to tip). The TRS end goes into the PS1 insert, the TS into the input of your effects unit. Be sure to label the cable properly.
If your not comfortable making a cable like this yourself you can buy a regular "insert" cable, like this and cascade it with a TS "Y-cable", like this. This will give you the same thing. These cables come in different lengths, so you can choose what you need.

Hello, Hilmar. I have been entertaining with Native Amer flutes both small and large audiences (200 +) for the past ten years using two MaxiMouse Speakers and a Boss RV3 Effects pedal. I am a 60 year old technophobe. You know those people who can't set the clock on the vcr? I go to them for help.But here I am with a state of the art Bose PAS and I can't figure out how to congifure my Boss RV3 and my new Boss Loop Station to give me that glorious sweet sound that I know the PAS is lauded for. I'm using a Shure SM58 mic on preset 01. The mic cable is XLR with a transformer phone plug 50k - 200 Hi Z to Low Z. I plug that into the input of the RV3. I come out of the RV3 output with 1/4 inch phone cable and go into the Loop Station input. I run a 1/4 inch phone plug directly out of the Loop Station into channel 1 of the PAS. Bad news. Sound is very muddy, cannot set levels and trims on PAS or remote high enough to project sound loud enough without much feedback. This configuration does not work. So now I'm reading your post about Effects Hookup 101. Guess I'm looking to set up my RV3 and Loop Station in a "serial effect." You say to get a 1/4 inch insert cable with 1/4 " connector on one side and two mono 1/4" connectors on the other side, etc...The Bose PAS Manual on page 20 has different instructions. Am so frustrated with this that I'm almost ready to return to the comfort zone of the Maximouse. Doing a Tai Chi conference in Oceanside, CA next month.Would love to feel confident about using the PAS. Help! Is it necessary to have a mixer for my set up?
I use a Loop Station with my PAS and bass. I've found that using an insert cable to connect the Loop Station gives the best results.

Start with the Master volume at 0 and the Channel 1 volume at 12:00. Once you've connected the Loop Station to the effects insert on channel 1 (Ring/R goes to the Loop Station input, Tip/L goes to output), set the instrument level on the Loop Station all the way to the right. Then adjust the trim on the PAS so you're getting a good strong signal (bright LED on the PAS). Turn up your master volume and play. If it sounds distorted, turn the instument level on the Loop Station down.

Hope that helps!
Saggio,

I'm sorry that you are so frustrated. We are in the process improving the manual (which really doesn't explain that very well).
Bill's description (Bill, thanks for helping out) is exactly right:
Connect you microphone directly to Channel 1 (no transformer) use an insert cable on Channel 1. Click
here for a list of "insert" cables that you can buy. Before you buy you should think about what length cable you need (i.e. how far will your effects be away from the power stand).
On one side, the insert cable has a 1/4" TRS (Tip-Ring-Sleeve or stereo) connector. That goes into the jack labeled "insert" on Channel 1 on the power stand. The other end of the insert cable has two "normal" (TS, Tip Sleeve, mono) plugs. One is labeled "Ring", "Right" or "Send" and is normally red. That one goes into the input of the RV3. Use a normal 1/4" cable to connect from the output of the RV3 to the input of the loop station (use the instrument input). Finally the other "normal" 1/4" jack of the insert cable, labeled "Tip", "Left" or "Return" (usually black or white) goes to the output of the Loop Station.
That sounds more complicated than it really is. After you have done it once, it should be relatively simple.

Hope that helps and please ask again if you have anymore questions and need more assistance.

Hilmar
Bill and Hilmar,thanks so much for your help. I have ordered the cable. I'll let you know what happens. Do I go half way in with that stereo phone plug in channel 1 of the PAS?

Hilmar, well here I am again weeks after you and others have instructed me about how to hook up effects to the PAS. I followed your instructions, got the insert cable, and made all the connections from PAS power stand to Elesis Nanoverb and RV3 Loop Station. Guess what? It works. SOMETIMES. Here's the neverending rub: Sometimes I get great, full 3 dimensional sound, (trim set at 10) when I play my Native Amer. flutes into the SM 58 mic or even my AKG 1000s.(preset 1 and 13 respectively) But if I decide to connect my Boss RV3 pedal to Loop Station instead of the Nanoverb, now the system freaks all over the place. Same exact settings on trim, presets, remote etc, but now massive screeching/feeback from system, and when I am able to settle the system down by lowering levels, I entirely lose my big, thick 3D sound. It's like I'm playing down a rain barrel. Been trying to figure this out for weeks, but I'm now at my wit's end. Thought the problem had to be in my effects units but now I'm leaning towards the PAS as the culprit. At least 5 times I have also had no power/sound when turning on the PAS. Comes back in a minute or so. I have a big Tai Chi conference to do in Southern Cal on June 24. I have zero confidence that the PAS is going to deliver. The system has been totally unpredicable, or I have been totally inept. If I pull one cord from the PAS, the Loop Station, the Nanoverb, or the Boss RV3, I'm back to zero control over the system. And I have no idea what I'm doing when normal sound returns. Someimes I've just walked away from the system and returned the next day to find everything back to normal. Go figure. Where do I go from here? HELP!!
Saggio,

I have a few suggestions for you in regard to setting up your effects. The first thing I'd do in this situation is to eliminate any possible problems with the Personalized Amplification System. I would set up the system with out any effects inserted. Play it for a while and make sure it is performing well. At that point try hooking up each individual processor in the insert. See if you notice any level drops or increases that are out of the ordinary. If that goes well then try pairing up 2 of the effects in the insert. I would suggest the RV 3 and the Alesis first. Then pair off the RV 3 and the RC20 Loop Station. Compare the two for sound quality and signal level. I am pretty confident that this is a level problem that is being caused by improper gain staging with the three effects boxes you are using. Check your Private Message Box if you need more help.
And (adding to what CJ said) please call us at 877-335-2673 for help. Our tech support team is fantastic. Give them the opportunity to help.

You don't need to go it alone ... this from a guy who never asks for diretions and calls only when I've exhausted all options. I can relate to your "I'll figure it out" style. Razz
