  • Page 4: Ii) Introduction

    Introduction Thank you for selecting a Manley Reference Series Microphone. This manual covers the Reference Cardioid, the Reference Silver and the Reference Gold Microphones. Our microphones are all hand crafted in the USA for maximum performance and reliability. These designs are optimized for extremely wide frequency response and exceptionally accurate transient response.

    U47. REFERENCE SILVER The Reference Silver is our newest microphone in the Manley stable. It went into production in 2017. This microphone is very distinctive with its silver, scale like body. The hand made capsule features a 5 micron evaporated gold diaphragm which is based on the vintage C37A.

  • Page 6: Power Supply

    1) Power Supply A separate power supply is required to power the Manley microphones. The tube electronics which are the amplifying devices in the microphone, require a separate high voltage source. The PSU connects to the microphone through the 6 or 7 pin XLR cable provided.

  • Page 7: General

    1) General Manley microphones will beat all others on grounds of sheer naturalness of sound without coloration or perceivable sonic signature. The design is optimized for extremely wide frequency response and exceptionally accurate transient response. Visually impressive, our microphones inspire confidence in artists and producers.

    2) Microphone Controls -10 dB PAD SWITCH, REF-CARDIOID & REF-GOLD This tiny switch near the base of the microphone body reduces the signal by 10 dB. Rather than changing the capsule voltage or adding a resistor into the signal path we chose a better technique. We change the amount of negative feedback derived from a dedicated transformer winding.
  • Page 9 Conversely, if you want more room sound, try moving the pattern select closer to OMNI. Compared to many microphones, the Manley Reference Gold Microphones exhibit less proximity effect for a given close distance. This, we feel is a clear advantage. Most engineers we consulted preferred the options of bass control from the console rather than the typical situation where a few inches of distance can make or break a take.

These patterns are marked on the control port as above. The REF-S achieves its directional response by subtracting sound that enters from the rear of the capsule, from the sound entering the front of the capsule.

    4) Circuit Topology The tube electronics found in the Manley Reference Series Microphones consist of two triodes per capsule in cascade, forming an entire gain-block. The tube employed in the Reference Gold and Reference Cardioid is a dual-triode 12AX7 and the tube used in the Reference Silver is a 5670 dual-triode.

    5) Troubleshooting NO POWER, NO INDICATORS - Check the IEC cable is plugged in firmly. PSU may be in protection mode, try turning the PSU OFF, wait 2 minutes then switch on again. Check the fuse on the back panel. A blown fuse often looks black inside . Try replacing the fuse with one of the same value and size.

  • Page 14: Servicing

    6) Servicing As discussed before it is possible to remove the working “guts” from the microphone body in one operation to replace a tube. Please follow the procedure below; 1. Turn the power supply off, disconnect it from the wall, and disconnect the 6 or 7-pin cable from the microphone.
