Traditional NXTs IN STOCK
Get yours now!
This is an amazing value -- for our upright bass-playing friends who want an EUB that can "sub" for the big bass, we've done all the upgrades for you -- and even put a custom "traditional" finish on the bass.
You get all the modern ergonomics and portability of the NS Design Electric Uprights, but with the Traditional string set for a more authentic doublebass sound (and bowability). We've also had NS Design upgrade the tuners to the CR-spec Schallers. And the cool traditional brown finish, over the veneer, looks classy and traditional -- and we even include a set of f-hole decals you can optionally install on the bass.
Available only as a four-string, the bass is the current NXTa "active" model, with the built-in flash-rechargeable buffer circuit. You can't get this exclusive model anywhere else, folks. Read more!
Ingles SA-22 stands are IN STOCK AGAIN
We ran out of SA-22 Upright Bass Stands
a couple weeks ago, and were told not to expect that new stands would be available until after Christmas. But, lucky us: they arrived early, and we got several pallets full, so they are now BACK IN STOCK and ready for IMMEDIATE SHIPMENT.
Certain microphones (and other devices) have onboard electronics that require electricity; "Phantom Power" is a very common method of powering these devices. It's called "phantom" power because it works "invisibly" by sending DC power back to the device using the same
microphone or instrument cable that carries the audio signal from
it. One cable, two jobs!
Phantom Power is best known (and most often used) as a power source for condenser microphones (like our K&K Sound Golden Bullet Mics and the DPA 4099 Bass Mic), though many active DI boxes and preamplifiers can also use it to supply their operating power (like the K&K Pure XLR Preamp or the Fishman Pro EQ Platinum Bass, among others). As you can see in the image to the right, the same cable carries the audio signal FROM the preamplifer, while the mixing board sends DC power TO the preamplifier, all without adding noise to the signal. This makes it possible to use the preamplifier without draining the battery or using an external power supply.
VOLTAGE IS IMPORTANT:
There are two general types of phantom power microphones: the more common type that typically uses XLR (aka microphone) connectors and requires between 12-48 volts, and the type ordinarily used with "mini" condenser mics that uses approximately 9 volts in parallel with the signal cable. The 9v type is usually terminated with ¼" phone plugs rather than an XLR. Because they use different voltage levels, they are not interchangeable.
Phantom power supplies are often built into mixing consoles, microphone preamps and similar equipment. Alternatively, a separate dedicated unit can be inserted into the microphone circuit as required. In the case of the Golden Bullet Microphone, the mic comes with its own dedicated "power box" which is operated by a 9v battery and passes the audio through to your amplifier or mixing board.
Though a large variety of units can either supply or use "phantom power," the manner in which they do so (and the voltages they use) can vary, and one must exercise care to ensure that the individual pieces of equipment they are using are compatible with each other. For instance, the K&K miniature condensers (Golden Bullet/Trinity mics and systems) use a 9v current sent through a standard ¼" instrument cable. Yet the phantom power used to power the DPA 4099 Bass Microphone, Fishman Pro-EQ Platinum Bass or the K&K Pure XLR use the common 12v-48v "standard" used by most studio equipment; it is sent through a three-conductor XLR (microphone) cable, usually powered by a recording mixer or PA board.
It's usually easy to determine which units are compatible; in our product descriptions, we include the specs for voltage when a unit has phantom power capabilities or needs. Many of our product pages also have links to manufacturer instructions and product manuals, and these will cover their phantom power specifications in more detail.
