MXL 770 Professional Cardioid Condenser Microphone - Studio Recording, Podcasting & Voice Over Upgrade

Product Description

We offer a comprehensive upgrade for the MXL 770 that transforms the mic into a true large condenser multipattern powerhouse.

Benefits

• Three polar patterns (Cardioid, Omni, Figure-8)
• Includes your choice of large-diaphragm capsule: RK-47, RK-87, RK-12
• Pristine signal path lowers distortion and noise while increasing sensitivity

About the Upgrade

We replace the mic's stock capsule (a 22mm small-diameter model with surprisingly not-smooth response that takes EQ poorly) with a true 34mm large-diaphragm, gold-plated capsule. The new capsule has higher output, lower noise, and a significantly more musical frequency response.

We replace the mic's circuit with a hand-built custom variant on the classic Schoeps design. Our circuit replaces the mic's HPF switch with a 3-way polar pattern switch. The switchable pad feature is retained. The new circuit incorporates more than a decade's worth of optimizations and improvements; it is implemented entirely with premium components.

Be aware that the MXL/Monoprice mic body shows icons for the high-pass filter switch. After the upgrade, this switch is a 3-position polar pattern switch. We are not able to paint or engrave new switch markings on the mic body. See our if you prefer to have correct labeling for the pattern switch.

How It Works

Reserve your upgrade by ordering the service from this page. Then ship your microphone to us. See the notes about that process . We will contact you with the expected upgrade timeline (typically 3 business days) and return shipping date once we've received your microphone.

When you send your MXL 770 or Monoprice 600800 to us, be sure to note your choice of large-diaphragm capsule on the service request form.
