Title: New Pueblo Preamp Coming
Post by: pohaku on November 10, 2016, 07:26:29 PM
Just a heads up, Pueblo Audio, a maker of really nice studio microphone preamps, is in the process of designing and manufacturing a battery powered microphone preamp.  They are also designing and manufacturing a battery powered DI box, which will be the first product out.  You can find the discussion string on GS:

https://www.gearslutz.com/board/remote-possibilities-acoustic-music-location-recording/1107671-battery-powered-preamp.html

The web site is: http://www.puebloaudio.com/index.html

In an off board conversation, Scott at Pueblo indicated that he was also working on a stripped down model specifically for the Taper market.  Battery life on his prototype Pre was 50 hours with phantom running to a Schoeps mic.

It sounds like this might be available in the first half of next year.

Given the declining number of separate battery powered preamps available to us, this sounds very  interesting - especially since it is coming from an existing manufacturer of well regarded studio preamps and will be tailored to the Taper community.  While a lot of us have moved to all in one recorders, I still appreciate having the option of running a really good preamp or two in front of my recorder for some shows.

Just put a deposit down on a unit, so I am hoping to pick one up out of the initial production run.  Pueblo pres keep company with Gordon, Forssell and Pendulum products.  I'm really interested in seeing/hearing this unit.

More info on the upcoming Pueblo preamp:

As of this writing, the ISLETA design is planned to offer 0dB to +80dB of gain, full-spec Phantom Power, and transformer-balanced floating outputs. Depending on microphone powering needs, battery life will sustain for 48-72 hours!  The price is projected to be $1,099 USD (batteries and charger not included).  Size will be approx. 6"x8"x2".   In addition, the design is being leveraged to accommodate an even more affordable "lite" version.  This version would offer unbalanced outputs, omitting the output transformers.  Price for the lite version is projected to be approx. $799.  All prices and features are subject to change.

Scott at Pueblo is interested in hearing what the Taper community might want in a battery powered preamp.  Right now, the "lite" version is the model oriented towards our community.  I have suggested that he also provide a mini jack output.  He thinks he could also lower the price by using less expensive non-stepped pots (the standard model pots are stepped).   That might get the price down to $599 - $699 or so for a high end two channel preamp.  Batteries are extra, but he is building this to use easily replaceable, commercially available off the shelf batteries at @$39 each.

So, if you have suggestions and ideas about what you would like to see in a pre, now is the time to let him know.

FWIW, I have no affiliation with Pueblo.  I just want to see a good pre get developed.

Thanks!

I really like the two pot approach I can use on my SD702..  one pot for gain the other pot for adjusting balance, as apposed to two gain pots.

Pueblo has an interesting approach where they make the power supplies and phantom supplies for their rack mount preamps as all separates. Even on their two channel pre that has the phantom power onboard you have to jumper the P48 to the mic input. I guess anywhere you can eliminate noise is a good thing.

My suggestion would be to have combo XLR/TRS ins and outs if you have the room in the case and to include an unbalanced 1/8" TRS output. Lots of hobby tapers use handhelds with mini inputs.

Have you decided yet if the XLR In/Out will be on the rear or the side of the unit?

Hi,

The plan is for side mounting. Since portable recorders often have their xlr on the sides it seemed practical to follow suit. Side mounting also simplifies manufacturing thereby increasing affordability of the final product. I am open to further ideas on the matter...

In addition to the transformer-balanced main xlr outs, there will also be an auxiliary unbalanced output on 1/8" mini trs jack. This is a separately buffered, tranformerless output; akin to the Aux Outs of the standard Pueblo range. Useful for feeding a back-up recorder, cue sends, etc.

Targeted for second quarter.  Hybrid DI box is coming first.  May have adjustable input impedance.

Preliminary measurements:

Gain Range: 0dB to +80dB [all gain, no pads]
Gain Matching: ±0.1dB between any channel, any box
EIN: -131dB [gain=+60dB, 50Ω source, 20-20kHz, unweighted]
Max Input or Output: +30dBu [unity gain, 10k load]
Freq. Resp.: 1Hz-200kHz [-3dB], 10Hz-40kHz [±0.1dB]
Common Mode Rejection: >110dB [50Hz, +60dB gain]

GS discussion thread is here:

https://www.gearslutz.com/board/remote-possibilities-acoustic-music-location-recording/1107671-battery-powered-preamp.html


FWIW, I do have one on order (I ordered the standard box, not the lite version) and would be happy to report on it once I get and have a chance to put it through its paces.  I believe a few other folks here also ordered one, although I am not sure which models.

Sweet thanks for the info man :) Looks like a really HQ preamp that I'd LOVE to run a few times :)

An update from Pueblo.  DI box is now launched.


"With that project launched, attention can now be focused on completion of
the ISLETA.  The circuit design is all worked out.  The main task ahead is
now the design for the chassis.  Attached below is a conceptual drawing of
the
ISLETA front panel.

Standard Features:
1.  Power On/Off switch
2.  LED indicator of battery condition.
3.  Phantom Power switch
4.  Input Impedance Selector: 3k/13.6k (custom values below 13k
available)
5.  +2.5dB to +60dB, 24 position Gain Switch.  2.5dB per step.  ±0.1dB match.
6.  Second stage gain can provide selectable +20dB, for a total max gain of
+80dB.
7.  Main XLR output: ultra-high performance transformer balanced output.
8.  Auxiliary 1/8" Stereo mini-jack: unbalanced transformerless output.

Price is still targeted at $1099 (batteries and charger not included).
The final chassis design will have a significant influence on the ultimate
price.

More information to come.  Thanks for your continued interest!"

Here is a working prototype.  You can also look at the new DI box on the same site to get a sense of the design aesthetic.  They included some artwork with the update e-mail, but it wouldn't copy for posting.  I have the transformer model on order.  I believe a couple other members here do as well.

Hi David & All,

Apologies for delayed updates. This band from Ireland has been monopolizing my attention for the last few months with 30th anniversary projects and such.

Because of the above I have not only neglected ISLETA news, but also overlooked announcing on GS that our new OLLA Hybrid DI Box was released last month! I am very pleased with how it turned out (pic attached). Great versatility, faultless sound quality, and sweet looking stainless-steal construction. Gratified to be receiving happy, positive feedback. In its first month, over half the first production run has already been sold off.

Back on topic, the ISLETA circuit board is designed and parts have been purchased and stocked. Completing a great chassis design is the last challenge. At this time I have aim on late 3rd quarter.

Thanks for your continued interest and patience

I can't wait to see the Isleta when its finished! The prototype looks like its in the same case as the Naiant MidBox to me. Obviously just a prototype, but I love that they're focusing on a small 2 channel battery powered version geared towards US tapirs for a change ;D

Thanks for the link yinz guys!

While it will be portable and battery powered, I don't expect it to be either tiny or light (especially if you order the trafo version).  More geared to open taping rather than stealth methinks.

I sent an e-mail to Pueblo Audio today requesting an update on the timeline for the release of the ISLETA.  I'll post their response when I receive one.

Dear Isleta Followers,
The effort continues to perfect the chassis for Isleta.  It is proving to be a challenge to design and fabricate a chassis that is strong, lite weight, ergonomic *AND* affordable.  Add to that an unexpected, yet welcome upturn, in orders for our existing products plus my intimate involvement with a little band from Ireland's upcoming world-wide release, and well...  its just taking longer than I would have expected to complete this product.

But continue it does.  Investments in R&D, parts stock, etc. are well into tens of thousands so we are committed.  Have no fear, ISLETA will be born!  I am very excited for this product.  Though I say it myself, I do believe this will be a game changer.  I do not know any product that will deliver the feature and extreme audio quality will being completely off the grid for days on end.  Attached is a rough drawing of the side view showing the main outputs and 1/8" stereo aux out.  Also a picture of the prototype in a production sound bag, on location for a documentary shoot.

Good things to come for sure.

All the Best,
