The Manley Reference Cardioid Tube Microphone has that “finished” sound right out of the box, making it the favorite vocal mic of top producers and voiceover artists alike.

This is modern pop music’s go-to mic: flattering, present, and larger-than-life. Some refer to the Manley RefC as the “Just Add Talent” microphone.

DETAILS

 

The Reference Cardioid Microphone shares the same electronic attributes as the Gold Reference Series, but has a center-fixed cardioid-only capsule with a thicker gauge (6 micron) gold sputtered diaphragm. With the similar film thickness and construction, similar high frequency resonance (a little edge), similar proximity effect and pretty good immunity from pops and sibilance problems, our Reference Cardioid more closely recalls how many of the vintage European tube mics such as the beloved U47 sounded like when they were new. Its rich tonal balance and liquid character is consistently admired for instruments such as guitars, drum overheads, saxophone, and especially vocals. With your present mic, if you find yourself leaning on your compressors and boosting 5 or 10K to score a bit more testosterone, then the Reference Cardioid just might be the mic you’re looking for to cure what ails ya. If you seem to be constantly boosting 12-18K and trying to get a clean, intimate sound, then probably the Reference Gold would be the safest bet.

If you want to sound like God, then use the mic Don LaFontaine used! The Manley Reference Cardioid mic. And have a voice like his, too.

FREQUENTLY ASKED QUESTIONS

How to change the O-RINGS:

The mic suspension is held onto the mic by a set of red silicone o-rings connecting FIVE pillars surrounding the mic, one set on the top and the other on the bottom of the mic. There are two sets of stainless steel screws and spacer nuts that hold the silicone o-rings onto these points and all you do is loop the o-rings onto these posts inner and outer. You can double up the o-rings for extra security and put two of 'em on each point and order two sets (20 total) if you'd like to.

If you needs to order more o-rings, you can order a set of them from our parts store, www.tubesrule.com. They are RED SILICONE #114 O-RING's.

How to change a TUBE:

Disconnect the power cable at the mic. Do not remove the mic suspension. You never need to. Remove the three phillips screws at the base (red part) of the mic that hold the case on. Grasp the body of the mic with one hand, grasp the base with the other hand. Carefully pull at the base of the mic (sometimes a slight twist will help), and slide the base out of the body just enough to expose the tube. Grasp the tube while holding the tube socket, and wiggle and pull to remove it. Install a new tube and put the case back on.

BUZZ! My mic started buzzing! Those damn bees... 

First thing I would check is that all the case/chassis screws are in nice and tight and making good ground to exposed metal. Remove the 3 x silver phillips screws that hold the cover/case onto the mic. You can slide the body of the mic up a little bit to check the holes on the base. Slide up and wiggle. (The base and guts of the mic are all contained by a sub-chassis.) Make sure there is silver metal on the case housing in the countersink and also under them on the base piece. Use a 1/4" drill bit in your hand and turn and press the drill bit a few times to make sure you have exposed silver metal showing in those places. Put the screws back and test. Next: There are some little set screws around the circumference of the base piece hiding in their holes. Using 1/16th allen key, back them out and run them back in. These are the guys who hold the XLR connector in place. We use stainless steel ones these days. Try those and re-test.

If the buzz is still there, with the mic on, see if touching the screen or top of the screen makes any buzz go away. Hold the XLR cable shell so you are making the ground path. If the screen is loose, it will need to be expoxied back in place with silver conductive epoxy. If touching the case makes the buzz go away then we still have grounds not being made so repeat steps 1 & 2.

Next would be to replace the tube with any good working 12AX7 or 6072 you have kicking around to see if it is the problem.

Next would be more advanced, checking the power supply volts, especially the heater regulator to make sure you have 12V coming off him... looking for a bad cap in the PSU that isn't doing his job of removing ripple, etc. If nothing you try works then we'll arrange an RA# for you to send it in. 

You can fill in the service form here to get that going or to request a schematic.

Where is my mic's serial number?

The Manley Reference Microphone serial number is located on the inner face of the mic suspension plate flanking the hole where your mic stand attaches to the mic suspension.
