SPLITCOMPRO

Mic Splitter/Combiner

Use the SPLITCom Pro to Split or Combine balanced low impedance microphone signals.

As a Splitter: The SPLITCom Pro provides one direct-coupled output and one isolated output from a single microphone. Applications include sending the direct output to the main or FOH mixer, and the second isolated output to a monitor or recording mixer. The MAIN MIC OUTPUT passes phantom power from the main mixer to the MAIN MIC INPUT for use with condenser microphones. Phantom power is blocked from passing to the ISOLATED MIC OUTPUT.

AS A COMBINER: The SPLITCom Pro provides one output from two microphone inputs. The PHASE switch can be used to invert the relative phase of the ISOLATED MIC INPUT. Applications include dual micing of percussion instruments, choirs, and instrument amplifiers. Phantom power passes through each output to their respective input, (MAIN to MAIN, ISOLATED to ISOLATED), however phantom power is blocked from passing between the MAIN and ISOLATED signal paths. Only the audio passes between the MAIN and ISOLATED signal paths (it is present on all inputs and outputs).

Features:
  • Low Distortion with Wide Frequency Response
  • Two Functions In One Box - Combines And/Or Splits
  • Phase Invert Switch For Subtractive Combining
  • Galvanic Isolation To Block Phantom-Power Between Channel
  • Ground Lift Switch To Reduce Noise Due To Ground Loops

Shure
In-Line RF Interference Attenuator

The Shure A15RF reduces interference from AM radio stations that may bleed into microphone lines when using long cables in microphone installations such as suspending choir microphones. The A15RF passes phantom power, and can be used with condenser microphones.For best results, the A15RF should be installed at the end of the cable nearest to the microphone. In situations where this is not practical, the A15RF can also be installed at the mixer input, although RF attenuation may be somewhat reduced.

In cases of extreme RF interference, two or more A15RF's can be placed in series in the same microphone line, preferably with one at each end of the microphone cable. In cases where interference is present but not audible, the A15RF can improve perceived sound quality by removing low-level interference components from the audio signal path.

Or the center for maintained action. If a particular configuration is desired they may be ordered that way from the factory. Otherwise button down latching is the default from the factory.

Features:
  • Passes Phantom Power
  • Balanced Female XLR Input and Male XLR Output jacks
  • Activation Switch can be either Latching or Momentary Mute
  • Reversible Activation Switch “Up” position can be mic on or off
  • Can be stand mounted with the Rolls MSC106 mic mount accessory

USBDUALPREPS

The USB Dual Pre is a full-featured high quality dual portable preamplifier and computer interface packed into a compact rugged case.

It is designed to work over a wide variety of applications from remote field recording to desktop/studio tracking. Each of the two low noise input channels has up to 48 dB of clean gain with signal present and clip LED indicators. Inputs can be either XLR balanced or 1/4-inch TRS. Each of the 1/4-inch TRS outputs is buffered low impedance balanced.

The USB Dual Pre is powered via the USB bus. An internal 9 Volt battery, or optional external 12V power supply (or any combination of USB, battery & power supply) can be used depending on application. When running powered by battery alone, you should expect in excess of 50 hours of operation with phantom power off. Battery life will drop to approximately 20 hours (depending on microphone) when phantom powering is engaged (still enough time to get through an average session).

The built-in low noise +48 Volt phantom power supply allows you to power up to 2 microphones as well as the preamplifier when running from any power sources including the USB bus.

For monitoring, an 1/8-inch TRS mini headphone jack with level and monitor mix controls on the rear allow for latency free local monitoring of the inputs while recording as well as playback monitoring of the USB bus. The monitor mix is also routed to the 1/4-inch TRS balanced outputs. This lets you use the 1/4-inch outputs as either preamplifier outputs or as the monitor feed to your powered monitors.

The USB interface is fully compliant with the USB 1.1 specification and uses USB adaptive mode for playback and USB asynchronous mode for record. It will work with the USB audio device drivers built into Windows 98SE/ME/2000/XP/Vista and Apple OS9.1/OSX computers with native USB support. No special drivers are needed.

Features:

  • USB Connectivity to Desktop and Laptop Computers
  • Low Noise Fully Balanced XLR and 1/4-inch TRS Combi Inputs

Mic Tube Duo Stereo Tube Microphone Preamplifier

Natural tube warmth for any mics or instruments.

Add warm, vintage tone to any pair of mics or instruments with the MicTube Duo preamplifier. Ideal for any recording or live setup, the MicTube Duo features an easy-to-use control layout and one of the most classic sounding, lowest-noise vacuum tubes: the legendary 12AX7. Aside from the tube, the MicTube Duo features a minimized circuit path, so it preserves the essence of the signal coming from the microphone faithfully.
