Double Bass NEW Euphonic Audio iAMP Doubler

this thread is getting long, and it is difficult to find things.

at the risk of re-asking something, has anyone gotten a hum when you use the Doubler's phantom power for certain mics requiring a preamp? i never had any issue with the AI Focus or Clarus on this, but with the Doubler i cannot run, for example, the AMT SB25 on phantom power.

The only Doubler I tried had this exact same thing going on when paired with my AMT. It was enough to keep me from buying it as I loved everything else about it.
 
I use fdeck's HPF-pre on my DB because I like have phase reverse and HPF on the pickup as well as the mic channel (I've been using both together lately). I run my EB right in the front (occasionally with pedals, but nothing on all the time as a preamp).
 
Good point, does the mute switch still mute the DI when you do that?

Page 9 of the manual (on-line on my site)

JP4 - Configures the Mute Switch. The Mute Switch always mutes the speaker out. Additionally:

It then goes on to show jumper positions to separately have mute affect, or not affect, the tuner out and the DI output. Each has its own setting.
 
Hi Peter:

I'm just about to order a Doubler and want to ask about the HPF. A number of pages back in the thread several TB'ers provided somewhat conflicting information on which channel is affected by the HPF. The last I read-and Mike Denim seemed to confirmed- the HPF affects both channels. I assume this means that-unlike my AI Focus-once the HPF is set, it will affect both upright and electric bass signals if one is doubling on these instruments. I'm just wondering if you (or anyone else reading the thread) could confirm this situation. Quite honestly, I double different basses with the AI all the time and use the HPF very often with upright bass but never with electric bass.

I almost never use the HPF hopely someone else will have an answer for you.
