We have developed a number of devices to amplify and record a number of acoustic instruments. On this page you’ll find demonstrations of some of  our devices and features. The demonstrations are not at all complete, but are good examples of basic capabilities and features, sometimes in demanding acoustic environments.

You can just watch the videos and skip the descriptions below, because each video self describes with on-screen text. The text below on this page adds some helpful information, but is not necessary.

String Quartet Demonstrations

These videos demonstrate the results of the Your Heaven® CloseUp® String System devices for violin, viola, and cello (string quartet). There is also a version for bass.

These string instrument examples were all recorded at a live concert at RISD’s Metcalf Hall. It has a wood floor stage, and the string quartet played in their normal arrangement, a five or six foot semi-circle that is graphically represented in the video. Each instrument was recorded through one of our specialized devices to a separate track, then mixed, without effect except for a small amount of reverb. The performance was simultaneously recorded with an Audio Technica AT822 (X-Y coincident stereo microphone) placed 4 or 6 feet away from the front-most strings. The video format is used to allow descriptive text, which should be self explanatory when watching.

Beethoven String Quartet No. 13

The music in these two examples is from Beethoven String Quartet No. 13, op. 130, Movement 5 (“Cavatina”).

This first one demonstrates the isolation achieved. The mix of the four tracks was not altered at all – each solo’d section is simply the three other instrument tracks muted:

This one compares the mix of our 4 mics and the AT822. The main point is that we have a lovely sound, in our honest view easily competitive with the well recorded acoustic sound of the instruments:

Different Trains

This example is from Steve Reich’s “Different Trains”, performed at the same concert.

• The piece involves a live quartet accompanied by prerecorded tracks (three other string quartets, recorded train sounds, and recorded speech, all supplied on a CD that comes with the rented parts).
• The instructions specify for the musicians to be amplified in a particular way, and to have monitors loudly playing the prerecorded tracks directly at them. During rehearsal, the violist (closest to one of the monitor speakers, inches from his foot) complained that it was hurting his ear, so the engineer turned it down to just the point where it did not hurt.
• There was also a much louder PA system aimed at the audience, playing both the prerecorded tracks and the quartet amplified through our system.

The AT822 ‘room’ recording alternates with solo’d instrument mics (with no reverb added). It demonstrates even more dramatically how well we isolate while still getting an excellent representation of the acoustic sounds:

Drum Demonstrations

Here are examples of the Hi-Hat Remover function of the Your Heaven® CloseUp® EzQ® Snare Drum System. This function greatly reduces bleed of the hi-hat into the snare mic, allowing the user to adjust their levels and pan and apply effects almost completely independently.

The first one is the most telling of the Hi-Hat Remover demos, if you’re in a hurry, just watch this one.

Snare Drum with Hi-Hat Remover (HHR) – Snare sound not affected while HiHat sound is reduced.

This is a demonstration of the Your Heaven® CloseUp® EzQ® Snare Drum Microphone channel of our drum system. The effect of the Hi-Hat Remover function is demonstrated in four sections, described in text on the screen as they happen. You will hear:

1. Play only Snare, turning HHR control barely affects sound.
2. Play HiHat with Snare – control reduces HiHat but no change in snare sound (as in #1)
3. Play only HiHat – hear drastic reduction of HiHat sound
4. Repeat of #1, here for contrast after HiHat change in #3.

The Snare and HiHat hits were all recorded live in one take, no changes of microphone or anything else. The only thing changing is the actual knob you see being turned. Everything else remains untouched.

Snare Drum with Hi-Hat Remover – stereo placement flexibility

This is a demonstration of the Your Heaven® CloseUp® EzQ® Snare Drum Microphone, as recorded with our complete drum system in a recording studio. Aside from allowing better control over the sound of each instrument, the system also allows unusual ease of stereo placement of the individual drums.

The effect of the Hi-Hat Remover function is demonstrated twice – section one with Hi-Hat moving, section 2 with Snare Drum moving. You will hear that the location and tonal quality of the fixed (non-moving) instrument is unchanged, while the other instrument is hard-panned to extreme L and R positions. The mix itself was as for use in a piece of music, and was not altered for this demonstration. The only thing that changes in each of these mixes is the pan control for whichever instrument is moving. Everything else remains untouched.
