MXL OS1 KR OverStream Bundle 990 Blaze Microphone Desk Arm Shockmount

MXL OS1 KR: A Streaming Desk Built Around the 990 Blaze

The MXL OS1 KR is an OverStream bundle pairing the 990 Blaze condenser microphone with a BCD-Stand desk-mounted hinged arm and an SMP-1 shock mount with integrated pop filter. A streaming or podcasting position has three physical problems to solve before any audio is captured: getting the capsule close to the mouth, keeping it off the desk that a keyboard is being hammered on, and stopping plosive blasts from ruining the take. Each of the three items in this package solves exactly one of them, which is why the bundle exists as a set rather than a pile of accessories. The result is a broadcast position that is assembled once and then simply swung into place at the start of every session.

Three Components, One Purpose

Included are the 990 Blaze microphone, the BCD-Stand hinged-arm desk stand and the SMP-1 assembly that combines a suspension shock mount with a pop filter. No XLR cable and no USB interface ship in this configuration, which is the single most important thing to know before ordering, because the 990 Blaze is an XLR microphone requiring 48V phantom power from an interface, mixer or preamp. Anyone who already owns an audio interface has everything they need the moment the box is opened; anyone starting from nothing should plan for an interface and a cable alongside it. Being clear about that boundary prevents the frustrating evening where a new microphone sits on a desk with nowhere to plug in.

The BCD-Stand Hinged Desk Arm

A BCD-Stand mounts to the edge of a desk and carries the microphone on a hinged arm that swings through a wide arc. Desk arms matter far more than they first appear, because a microphone on a tripod sits on the same surface as the keyboard and mouse, and every keystroke travels through that surface directly into the microphone body as a low thud. Lifting the microphone onto an arm that clamps at the desk edge breaks much of that path, and the hinge lets a streamer push the whole assembly out of the way to reach a drink or read a monitor without moving the stand. Gamers who lean forward during intense sequences get the additional benefit of an arm that follows them rather than a fixed position they have to sit still for.

A 32 mm Capsule Behind a Lit Grille

Inside the 990 Blaze sits a 32 mm capsule carrying a 6-micron gold-sputtered diaphragm, rated at 15 mV/Pa sensitivity, 200 ohms output impedance and a 20 Hz to 20 kHz frequency response. The Blaze identity comes from red LED illumination in the grille, which serves a genuine function on camera: a lit microphone gives a video frame a focal point and a splash of color that flat studio lighting often lacks. Underneath that visual layer the specification is a conventional pressure-gradient condenser with 130 dB maximum SPL at 0.5 percent THD and a 20 dB equivalent noise level. A creator gets a microphone that photographs well and a signal chain that behaves like a studio microphone should.

Cardioid Rejection at a Busy Desk

Cardioid is the fixed pattern, and at a gaming or podcasting desk it is doing constant quiet work. Sound arriving from directly behind the capsule is attenuated most, so with the microphone in front of the presenter the rear null points back toward the desk, the chair and frequently toward a PC tower whose fans run hard under load. The SMP-1 contributes to the same goal from a different direction by suspending the microphone on elastic elements, so knocks transmitted into the arm are absorbed before they reach the diaphragm. Together the pattern and the suspension mean a stream can run for four hours without the audience hearing the room the streamer is sitting in.

Connecting It and Who It Suits

Connection is a balanced 3-pin XLR carrying audio out and 48V phantom power in, supplied by any interface, mixer or preamp with a phantom switch. Game streamers, podcast hosts, voiceover artists and video creators are the people this package was assembled for, all of whom share the same need for a repeatable desk position that looks intentional on camera. A two-host podcast can run a pair of these arms from opposite sides of a table; a solo streamer clamps one arm and never adjusts it again. Everything mounts to a desk edge, nothing occupies floor space, and the recording position survives being pushed aside and pulled back a hundred times.
