How do I set up my cardioid?
The procedure is as follows:
- Place the microphone behind the enclosures, at the spot where we want the cancellation to take place.
- Start with just the band that drives the forward facing subwoofers.
- Measure the magnitude frequency response for the enclosures facing forward before doing phase adjustments.
How does a cardioid subwoofer work?
A cardioid subwoofer or subwoofer array produces a heart-shaped coverage pattern in which levels are louder to the front of it and lower behind it. The waves of sound radiate away from a subwoofer in a largely spherical pattern unless they are interfered with by a surface or by opposing pressure.
Where should a subwoofer be placed on stage?
It’s pretty common for most bands to place their subwoofers on either side of the stage, and that always seems to create heavy bass in the center. Whenever possible I prefer to line the subs up across the front of the stage, and when the stage is high enough, stack them 2 high across the front.
Is a subwoofer directional?
Almost all speakers are directional to some degree, so we don’t bother to call them cardioid, but subwoofers are a different story. They are all generally omnidirectional because of the laws of physics.
What is cardioid mode on blue yeti?
Cardioid – This mode uses the front-facing microphone to record directly in front of it. Omnidirectional – Omnidirectional uses all microphones within the dome to capture all sounds around it in an equal amount. This is great for recording live music or nature sounds.
Where should I keep my subwoofer?
A subwoofer placed in the corner of a room may increase the subwoofer’s output – causing the sub to sound louder. Try placing your subwoofer in a corner and see how it sounds. However, depending on your floor space, a corner might not be a viable option for your subwoofer if it’s too far from your listening area.
Can I put a subwoofer in a wall?
You can wall mount a subwoofer, but size, weight, and the vibrations that subwoofers generate may present practical problems. As an alternative, raise the subwoofer off the floor using a platform or furniture. But if you have to wall-mount, consider buying a subwoofer designed for wall-mounting.
Can subwoofer be placed behind couch?
While subwoofers are often placed in the front left corner of the room, putting a subwoofer behind the couch (as long as it remains 25-35cm from the wall) can be optimal and help with localization. To test the best location for a subwoofer in your space, use an SPL to measure frequency response.
What can I do with a cardioid subwoofer?
With a cardioid configuration, clarity will be gained on stage. A common subwoofer configuration is to group all the units together in front of the centre of the stage, forming a single line. Subwoofers may be fed a stereo signal or the output from a mixer’s aux group.
How are cardioid / directional subwoofer arrays, Part 1?
In live sound, there are several kinds of cardioid/directional sub arrays: Fig. 4: Meyer MAPP image of broadside subs placed across stage front, shown at 31 Hz. Image: Bob McCarthy Broadside Arrays, (Fig. 4) in which a number of woofers are arranged in a row, and the primary radiation is at right angles to the row.
What is a cardioid pattern in a subwoofer?
The sound pressure level measured in the direction of cancellation is reduced and the sound pressure level measured in the opposite direction is increased. When these measurements are graphed on a polar plot, the graph appears to be heart-shaped, so it is called a Cardioid Pattern.
How many boxes do you need for a cardioid sub?
A cardioid setup works indoors or outdoors and works with a minimum of 2 boxes no matter where you put them, unless they are under a stage or backed up against a wall. A combination of three boxes, with two facing forwards and one backwards, is the ideal combination however they can also be used in pairs.
