Is the Bang and Olufsen cartridge compatible with the MMC4?

This will make the cartridge compatible to MMC4 (or better). The MMC2 and MMC1 use ruby cantilever and a different diamond tip that we can not get at present time. That means those cartridges still can be fixed, however they will sound like a MMC4 with a better midrange and they should be treated like a MMC4 when you adjust your tone arm.

When did Bang and Olufsen start the cartridge repair program?

Back in 2009 we launched the B&O cartridge repair program and today we rebuild these cartridges for our Bang & olufsen enthusiast customers all over the world. Ever since we have perfected the cartridge rebuild procedure and our new cantilever/diamond tips exceeds the quality of the original MMC4 cartridges.

Why does my Bang and Olufsen voice cartridge not work?

A broken tip causes the tone arm not to track and the tone arm will skate inward on the record. A loose suspension causes distortion and one channel sounding different from the other channel. What we can not fix is when a channel is out. That means the voice coil is open and at that point we may have a replacement cartridge for you.

What kind of MMC4 cartridge do I need for Bang and Olufsen?

We now offer this newly manufactured MMC4 Soundsmith phono cartridge for these B & O MMC cartridges: B & O made a proprietary mounting system for their cartridges to fit in their tonearms so you cannot install other cartridge brands in B & O tables.

What was the frequency range of Bang and Olufsen?

Frequency range was 20-30,000 Hz ± 3 dB. Effective tip mass was a mere 0.5 mg and compliance was higher than 30×10-6 cm/dyne. Bang & Olufsen’s (then) most accomplished pickup cartridge was fitted to Beogram 6000. The MMC principle was adapted to track 4-channel records: both Quadradiscs and SQ.

Which is better the beocentral MMC 4 or MMC 5?

The MMC 4 was the most popular model in this range. It gave good performance and was fitted in the factory to most of the smaller turntables and mid-range music centres. In addition to what the MMC 5 offered, more refined performance was obtained by making the cantilever conical instead of straight and reducing the effective tip mass by 0.1 grams

What’s the name of the new Bang and Olufsen cartridge?

The MMC4000 was renamed the MMC20EN but was in most ways unchanged. At the lower end of the range , a new elliptical model was introduced, the MMC20E, and the range was completed with the replacement for the MMC3000, the MMC20S.
