Warm Audio Wa-1b Tube Optical Compressor
- Product Code: eq146895
-
Combining smooth tube-optical warmth with precision controls, the Warm Audio WA-1B is an accurate recreation of a legendary, top-tier Scandinavian compressor used by producers and engineers from Chris Lord-Alge to Rick Rubin. Like the original studio staple, the WA-1B features a winning compression formula that offers both the forgiving musical compression of tube-optical circuitry and the speed and control more closely associated with modern dynamics processing. The flexible combination works well on a variety of sources; allowing you get natural sounding vocal compression, control bass signals so they sit just right in the mix, and generally add professional-sounding compression that tames dynamics without destroying the musicality of the performance.
Handwired to authentically recreate the original true-to-spec circuit, the WA-1B combines custom large-core transformers from Lundahl Sweden, select tubes from JJ and Tung-Sol, and a premium high-precision optical element for ultrafast and accurate operation without sacrificing authentic analog warmth. The WA-1B delivers extended dynamic processing courtesy of its classic extended controls including infinite 2:1 to 10:1 ratios, variable threshold, as well as attack and release settings that can work in fixed, manual, or combined modes for added flexibility. Multiple metering options, dual side-chain bus connections, and a true bypass switch complete the professional feature set.

The WA-1B supports a variable threshold giving maximum control to the user regarding how much compression is applied to any signal at various input levels.
The WA-1B ratio is variable and has infinite controls between 2:1 and 10:1. From soft musical dynamic control all the way to hard-smashing compression.
The Attack/Release controls on the WA-1B are unique in that the attack/release operations can be switched to a fixed setting, manual (variable) setting, or combined setting. In the fixed mode, the WA-1B delivers the natural attack and release time of the optical element. The combined setting in particular creates the opportunity for a more nuanced release-time curve. This dueling time-constant circuit operation is a special feature of the WA-1B and its original inspiration.
The WA-1B meter switch has three settings: input, compression, and output levels. Set to Input, the VU meter reads the level at the input connector. Set to Compression, the VU meter is reading gain reduction. The steady state is 0, and the amount of compression is shown as the needle moving right-to-left away from 0 dB. Set to Output, the VU meter reads the level at the output connector.
Related Questions and Answers
Q: 1. How are the telescope focal length (1950 mm) and focal ratio (9.75) defined? Focal length is the distance from the focus to what? Focal ratio is the ratio of what to what?
A: Focal length is the distance (given in millimeters) between the telescope's primary lens or mirror and the point where the light rays come together in focus. The focal ratio is the focal length divided by the lens diameter. For the Vixen Optics VMC200L, that would be 1950 divided by 200 = 9.75.
Q: 2. Will this work with Canon's XF705?
A: Yes it will be compatible with the Canon XF 705 camcorder.
Q: 3. What dimensions of filter fit into the trays? I'm not accustomed to the circular filters for matte boxes. Would they work with 72mm circular lens filters?
A: The trays are not for circular filters, you can use 4x4 filters.
Q: 4. Hi I appreciate if someone can tell how many inches can be adjusted the height of the matte box in relation to the rods? Thanks!
A: Hello, thank you for the interest in Shape products. The height can be adjusted about 1 inch. Thank you, Shape team.
Q: 5. Can I use lenses with a diameter of 49mm in this mattebox or would there be any problem in?
A: Yes you can. This does have a universal Knickers for smaller lenses to block out light. You will need to have this matte box mounted on to a 15mm baseplate though.
Q: 6. Will this matte box cause vignetting when used with a 24mm lens? Paired with a full-frame 35mm image sensor.
A: Hello SamuelThank you for your question! You might indeed get a bit of vignetting when using this unit at 24mm. We are coming out with a 4X5.6 mattebox though in the next few weeks.We invite you to stay tuned if that could interest you.We hope this answers your question and we thank you for your interest inour products!Regards,The SHAPE team
Q: 7. What dimensions are the adapter rings?
A: Here's the dimensions of the rings included with the matte box:64mm, 68mm, 72mm, 82mm
Q: 8. Can I use my Meade LX85 German Equatorial mount & tripod with this OTA?
A: Yes, you can.
Q: 9. Will this lens adapter work for a tight room to record a remodeling project with a canon xa15? How wide is this lens adapter?
A: The Canon WA-U58 Wide Attachment Lens should work for a tight room as it will convert the XA15's 28.8mm lens into a 23mm wide angle lens.
Q: 10. I cannot find the two filter trays which were included into the Shape Matte box I bought some time ago. Do you know if it is possible to buy new filter trays separately? Or if it is possible to use other?
A: Please write us provideo@bhphoto.com with the model SHAPE Matte Box and we can find out for you.
