New Headway preamp

Discussion in 'Amps, Mics & Pickups [DB]' started by Fredrik E. Nilsen, Dec 11, 2019.


  1. Headway is coming out with a new EDB2 preamp in January. Separate EQ for each channel, and a few other improvements. Introduction price will be the same as the current model, GB £ 250. (Posted in a different thread, but may be of interest to others).

    sounds not too bad..:) but without "real phantom power" to use condenser mics no alternative for me...:p
     
  4. I probably should know this, but what do you mean when you say "real phantom power"?

    For (probably??) most Condenser Mics your 48 V Phantom Power to get them to work proper....
     
  6. It says 48v phantom on the XLR?

    Ups...:facepalm: sorry.. I think, I've "overlooked" something... I just saw the "11 V Phantom Power" on the left side of the picture and supposed to remember the "old" Headway missing th 48 v.. it was my fault not to look accurate enough...:p

    Very nice, the older versions of the EDB-2 only provided 18volts to the XLR for Phantom the if you look closely this revision gives you the full 48.

    yes.. I've been to fast thinking they made the "same mistake a second time...":p

  10. Good. I thought there was something I had misunderstood about phantom power. :)

    What knobs do you twist to manipulate the blend? The two gain knobs at lower left? And the only way to adjust blend is to slather on signal gain? Probably missing something obvious...?

    It's done via the gain knobs as you mentioned, so no blend knob per se. I think between the gain knobs and the master volume you can find the balance needed without too much issue, or at least i am able to on the current model of the preamp.

    But keep in mind this is clean gain...it will never dirty up your tone by increasing the gain on this unit.

  13. My thoughts too. I don't think this will be an issue.

    There has never been a blend knob on either the EDB-1 or the EDB-2. The Channel Volumes feed directly into the Master volume through a single EQ section, so they we’re essentially a form of blend control but unless they are set at the output level the device with the higher output will override the other. However, the timbre of the device ii.e. microphone vs peizo pickup also tends to override the sound that is created.

    Interesting .... so by depending on "timbre" for blend, the device presumes one input is a piezo pickup and the other a microphone. Seems weird but I guess it works since many of you use this. This does not seem useful for blending two microphones. I do this in a DAW where the blending is achieved by decreasing input volume of both mics (or even a third or fourth mic) to varying degrees. If it's tracked correctly, adding signal above 0dB is never required.

    The "front panel" diagram shows phantom power is switchable (off, 11V, 48V). The unit uses an 18V power supply, so it must have a built in DC to DC inverter.

    The Headway EDB-1 and EDB-2 both only supplied 18 volts to the phantom power and 12 volts to a TRS jack input on Channel 2. Since it opperates on 18v DC either from batteries or the powersupply, then yes
    there has to be an inverter to get the mic phantom up to 48v. That was a big complaint about the EDB-1&2. However, with the three different microphones I used with my EDB-2, none sounded compromised at 18 volts.
    it did raise the noise floor somewhat, but in a live performance that just dissappeared. if it was infact even audible. It worked very well with the Remic DB5400LB, the DPA 4099B, and the Xlson Chuck Israels.
    Even in a recorded example it didn't seem to be a significant issue.

    Well,
    I’ve only used the EDB-2 to blend a pickup, with a microphone, which is primarily what the Headway was designed to do. Channel 1 only has a 1/4” phone jack, Channel 2 has the XLR two microphones would require a additional phantom power brick. I have one of the Radial Stage Bug 48v phantoms.

    Any idea what dimensions are for the new EDB2?
     
  20. From the looks I would guess it's the same size as the old, give or take a few millimeters. If you want it specific, try sales@headwaymusicaudio.com. They are always helpful.
