Sound guy xmas idea #12 – PulTac Passive Tube Equalizer

Posted on by

Top shelf tube gear has never sounded so good and been so reliable.  Tristan has redesigned a classic and made it a price that’s hard to pass up.

Two channels of Passive and Inductor based Program Equalization!
Heavily modified version of the Pultec EQP-1, adding much more flexibility in the Low-End Boost/Cut, and in the High-Cut sections, with excellent Sowter inductors used in the High-Boost.

Single tube design, using one NOS Tesla/Sabre 6DJ8 per channel.
Hammond Transformers isolating both Inputs and Outputs.

You can buy one here:  http://audioaholics.com/peers/catherine_north for MUCH cheaper than most mono tube filters!

The Manley Massive Passive Stereo Tube EQ is a two-channel, four-band equalizer (with additional high pass and low pass filters) that can handle radical EQ sometimes needed for tracking as well as the most subtle shadings for vocals and mastering. It is designed to be a fundamentally different EQ but incorporates the best strengths of Pultecs, choice console EQs, parametrics and graphics. The difference is that the Massive allows twice as much EQ with half the coloration. It delivers huge HF boosts without sibilance problems and extreme fatness with impressive clarity.
Manley Massive Passive Features:
All-Passive tone sculpting circuitry
Unique Shelf curves use the “bandwidth” control
Overlapping and Interleaved Frequency choices
Every band switchable to shelf or bell
Vacuum tube make-up gain and line drivers
Parallel symmetrical topology
Premium components throughout
HP and LP Filters plus gain trims
Modular design allows future upgrades and special functions

Studio Vocal Microphone V4 U

Studio Vocal Microphone
New small-diaphragm capsule architecture, with bevelled collar for controlling the polar response.
Warm, clear sonic character with smoothly rolled-off diffuse-field response.
Capsule head with adjustable tilt angle.
Optimal on-axis frequency response featuring a mild high-frequency lift.
Very smooth polar response; carefully-controlled narrowing of the pattern at high frequencies.
Diffuse-field response parallel to the 0 ° response, with a gentle roll-off at high frequencies.
Newly designed electronics offer a very high maximum sound pressure level.

V4 U Studio Vocal Microphone
The V4 U is the studio vocal microphone by SCHOEPS.
It unites the outstanding technical characteristics typical of SCHOEPS with a timeless, classic design.

The “look” of the V4 U is based on the SCHOEPS CM 51/3 from 1951. But the V4 U is a thoroughly modern studio microphone. Its capsule, circuitry and mechanical construction are the result of extensive new development.

20100424 – Roxanne – a WBS R1200 resto mod

Posted on by

One of my first ground up restores. This was a console with 12 Mic pre-amps, direct outs, summing and a monitor. It had a “Red Light” on the meter bridge… so I added a switch that said “POTRL” that “Put on the Red Light” and so it became “Roxanne” It’s still in use today but could use some tweaks I’ve learned from experience. We’re working on a very similar project right now, so It’s very cool to look back and learn.

The biggest lesson: it’s hard to put a value on a labour of love and curiosity, but bill accordingly.

Mixing Surround Sound in headphones…

there is a demo below… check it out in cans

The Spatial Sound Card App is a software based, virtual sound card. It provides speakers for stereo and surround monitoring for the computer with standard headphones.

Professional monitoring of audio content usually requires complex, high-quality speaker installations, for which both budget and space are needed. The Spatial Sound Card enables monitoring of stereo and surround up to 7.1 with a standard headphone on the computer.

The Spatial Sound Card is a virtual sound card that is inserted between software, operating system and audio hardware. The room virtualizations originate from a constantly growing number of high end studios and dub stages like the ARRI Stage One, MSM Munich and others. The technology used in the SSC was used on major Blu-Ray releases (e.g. The Expendables I and II).

To optimize the virtualization the SSC provides parameters to customize the frequency curve of the used headphones. Presets for a lot of well-known headphone models are included, more will follow soon.

The Spatial Sound Card works with all applications that support multichannel audio output. These include media players like VLC and FLAC-Player as well as video and audio workstations. The SSC is recommended for media professionals from the audio, video or games area as well as for agencies and companies with workstations that need high quality audio monitoring.

For now the Spatial Sound Card runs on MacOS 10.6.x and above, a version for Windows will come within the third quarter of this year.
