Concerning effects loop and direct out

[bthiemann80]

I have a Genz Benz Shuttle Max 12.0 and want to run effects through the effects loop. I see no problem w/ it, but I want to know if I can still use the DI on the amp w/ the effects all pre-eq. Here's what it says in the online manual about the effects loops:

EFFECTS LOOPS – The serial “EFFECTS LOOP” jacks are provided to allow access to the signal for the purpose of inserting signal processing equipment such as compressors, chorus, delay & reverb processors. Individual pre-EQ loops are provided for the TUBE channel and the FET channel. An additional MASTER post EQ loop is provided for the summed (TUBE + FET) signal. This loop may also be used as a PREAMP OUTPUT or POWER AMP INPUT patch point. “SEND” (output) and “RETURN” (input) are nominal +4 dB level.
“Series” devices (such as compressors and gates) require that the signal flow out from the send jack on the amplifier, through the processing device and back into the return jack on the amplifier. Parallel or mixed signal devices (such as chorus, delay and reverb processors) require that the signal flow out of the send jack on the amplifier, through the unit where it is split into a dry (unaltered) signal and a wet (processed) signal. On the processing unit, you will use the mixed signal output to return the signals (both wet and dry) to the return jack on the amplifier. The ratio between the wet signal and the dry signal is heard as the amount of effects added back to the original signal, which is controlled by the mix knob (also called “balance”) on the effects processor. This may be a real knob (as in the Alesis® Microverb), or software controlled (as in the Yamaha SPX-90, SPX900 or SPX 990). Set the input sensitivity on the effects processor according to the manufacturer’s instructions.
The front panel MUTE switch will shut all of these outputs down when engaged.

.....So, i'm still kind of confused. As far as I can tell, it doesn't look like there is any information concerning effects loops, amp DI and pre/post EQ. Can anyone help me decifer this and tell if the effects will be able to go out the DI pre-eq?

The pre DI output is pre everything except the impedance translator head amp (input stage), therefore will also be pre effects loop.

If you want to use compressors or other devices in the channel effects loops you need to use the post position. The post position is also post master effects loop.

Gotcha, thank you agedhorse!

BTW, you guys engineered a hell of a great amp w/ the SM12.0, I've had mine for almost 2 yrs and it's been through some serious gig use w/out any trouble at all! I mean, it's been thrown down stairs, exposed to midwest humidity and weather outdoors as well as indoors and back and forth (all w/in a rack case mind you) but still never ceases to perform night after night. Thanks again!

You are most welcome, glad you are enjoying it.

I come from a pro touring background (pro audio) and understand the importance of building a rugged, reliable, real world amp. It's not all that hard, but does require understanding the rigors of the road which doesn't happen from behind the desk as you can probably guess.

Now, off to another gig...
