After 27 years since the debut of the first Manley Reference Gold and Reference Cardioid tube microphones which have since become modern classics, we introduce to you the Manley Reference Silver Microphone. The audio inspiration for this handcrafted beauty begins with the 1950s classic Sony C-37a microphone, and specifically with California capsule maker David Josephson's fantastic recreation of the C-37’s C-3 capsule which features an adjustable acoustic chamber on the rear of the capsule for the user to switch between Cardioid and Omni pickup patterns (see the adjacent photo for a close-up). This distinctive capsule is the heart of the rich and creamy tone that the Manley Reference Silver Mic delivers today, and reliably with a five year factory warranty. The old SONY mics are super-rare at this point, if you can find a decent working example of one!
Inside the mic, we are using a different circuit from our other two microphones. The fragile high impedance signal from the capsule first hits a FET sitting underneath the 5670 vacuum tube’s cathode which then amplifies the signal into a more robust voltage that our hand-wound Manley IRON® microphone output transformer sends out to your microphone preamplifier. Output level from this mic is a wee bit lower compared to our other two microphones, but after careful consideration coming through the Beta-testing phase of development, we decided to leave it there as this mic will find a forever-home in front of your loudest instruments such as snare drum, guitars, and toms. It's a real natural there!
Sonic character of the Reference Silver is on the rich and warm side. You'll find this microphone stunning with female vocals and saxophones, with a round character that is never sibilant or boxy. A brass section will sound rich and cohesive. This microphone with its bountiful and warm middle tonality also is a natural for drum overheads where you might have too much brightness off the cymbals from other microphones. It is a very classic sounding microphone, which is to be expected since its innovative capsule design harkens back to the 1950s. Use the Manley Reference Silver Microphone where you might be thinking about a ribbon, and use it with confidence!
The trailblazing power supply is a brand-new derivative of our wildly successful SMPS already in use in the Manley CORE® Reference Channel Strip, Manley FORCE® 4-channel microphone preamplifier, and Manley Nu Mu and ELOP+ Stereo Limiter Compressors designed for us by the worldwide experts in this technology, Bruno Putzeys and Nand Eeckhout. This power supply was designed for us, designed for vacuum tubes, and designed especially for audio fidelity. Numerous listening comparisons again prove the sonic superiority of this power supply. All lines are regulated, all rails come out at super-low impedance, and there is zero 50/60 Hz ripple component present in the chassis as the module runs at a much higher frequency well above the audible range. It is an efficient design in the high 90th percentile, and it functions it any mains input voltage from 90 to 250 V AC meaning no reconfiguration is necessary when traveling around the world. Just plug it in! It is a well-smart invention light years ahead of older linear power supply designs. We are going to brag about our awesome power supply, for sure!
Our proprietary precision suspension system is provided with each Reference Microphone (the capsule itself is mounted onto a rubber shock-mount.) Because the entire working "guts" of the microphone may be removed for service in one piece from the housing, it is envisioned that the microphone need not be removed from the suspension. We also provide a very useful swivel of our own design with every REFERENCE MICROPHONE; its T-bar handle and locking clutch action require no tools to adjust. And no MANLEY microphone would be complete without a genuine leather capsule protector which slips (and ties) onto the end of the microphone to protect the capsule when not in use.
Each REFERENCE MICROPHONE is packaged complete in a rugged carrying-case.
Like the other Manley Reference Microphones, all of the metalworking and construction is hand-assembled in the USA by our experienced staff in our Chino, California factory, located just 35 miles east of Los Angeles. We are sure you’ll love the organic nature of the intriguing artistic finish of the Silver Microphone as it will remind you about how natural and alluring the sound of this microphone is.

FREQUENTLY ASKED QUESTIONS
Why should I order replacement microphone tubes from you?
The microphone grade tube is tested at the factory for lowest noise, using a test fixture we have built that duplicates the Manley microphone circuit. To the best of our knowledge, there are no other tube vendors that have this purpose-built tester. This testing yields very few tubes suitable for use in the microphones.
Tube quality, especially noise characteristics, varies over time and batch-to-batch. At any particular point in time, we may be using a different tube than what is listed. There is nothing "special" about a Sovtek or Ruby, or anything else we use; what is special is the characteristics we grade and select for including the low noise requirement, and the testing required to insure this.
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.
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.
