Hello Everyone,
i'm a new to the audio world, and i'm new to the forum.

I'm currently planning to get a RSA Predator, but i have a few questions.
1) What does the "Gain" control do to the Amp? Like what exactly does it do?
2) I'll be using IAudio Cowon D2 with The Predator, but the thing is that i do not know what i can use to hold them both together.....perhaps a rubber band? any suggestions?
Thank You Very Much,
Tiyako

1.Basically in "layman's" terms, higher gain equates to higher volume. Usually harder to drive cans require higher gain to provide enough volume. This is just in simple terms.

2. Try on of those "livestrong" armbands or velcro, those seem to be the most common options.

The gain switch basically just gives you more volume options for lesser or more demanding headphones. For instance, I use the low gain for my IEMs and the high gain for my HD650's. What you want to do is start at low gain, and if you can turn the volume knob up all the way and still want more volume, turn it back down to zero, flip the switch to medium gain, and repeat.

I don't think the D2 has a proper line out connection... but the headphone outputs on Cowon mp3 players are pretty good and are quite ampable. I use the X5L and find that it does amp pretty well. I think you'd still have better luck with a proper line out, though.

As for attaching them, some use rubber bands or those elastic bracelets... some use velcro. It's sort of a personal preference thing how you lug your portable rig.

Good luck!

Does yours emit a slight hiss when changing volume?



Not that I've ever noticed. And I don't recall that from my Hornet. But that may be simply because I rarely change volume in the absence of a signal.

No, but if there is a slight static when changing the volume this has no effect on the sound once you have the volume where you want it.

Some amps may do that with the volume being changed, due to the feedback control in the amp, but it is only temporary while the volume is being changed. I haven't really noticed my Predator do that though.
