The Radial Engineering Studio-Q™ is a compact studio talkback controller designed to provide a simple yet full-function cueing system that allows easy communication with artists in a separate booth or on the other side of the control room glass.The Studio-Q begins with a centrally located talkback switch that activates the built-in microphone, illuminating a bright LED to indicate that the talkback channel to the artist is active. This is supplemented with an external mic input for a dynamic microphone, allowing a stand-mounted mic to function as the main talkback source, or act as an additional talkback mic for a producer. Both the internal and external microphone levels are set via individual trim controls along with a master mic volume. A Radial JR1™ remote footswitch can be connected for hands-free activation of one or both talkback mic's. When the Studio-Q talkback is active, the signal is routed to the studio headphone system while it automatically dims the program to the desired level. A separate program level control allows instant access to the playback volume feeding the headphone mix.Connecting audio to the Studio-Q is straightforward with balanced ¼" TRS program inputs and outputs. The external mic input features a standard XLR for a dynamic microphone, while the JR1 remote connects via ¼" jack. An additional 'remote out' ¼" jack allows you to send a dry contact signal to an external device when the talkback switch is depressed. This can also be set to carry DC power and accommodate a remotely powered LED beacon to attract attention when the artist isn’t wearing headphones or is in the middle of a take.Following Radial’s pedigree for robust manufacturing, the Studio-Q is made from heavy 14-gauge steel for added durability and shielding against stray magnetic fields. A compact chassis size reduces the footprint on your desktop, with rubber feet that protect the work surface while keeping it firmly in place. The Studio-Q is powered by a 15VDC supply which may be locked in place using a cable clamp.The Radial Studio-Q, a simple talkback system that improves communication and adds professionalism to your studio.FeaturesCompact desktop cue system for studio recordingAllows engineer & producer to talk to artistBuilt-in engineer mic and external producer mic inputImproves studio efficiency, workflow andprofessionalismSpecificationsAudio Circuit Type: Active with FET dim circuitsNumber of Channels: Mono or Stereo operationFrequency Response: 20 Hz to 20 kHz, ±0.5 dBNoise Floor: -86 dBuDynamic Range: 106 dBIntermodulation Distortion:< 0.005%Total Harmonic Distortion:< 0.007%Input Connections: 1/4" left/right program inputs, 1/4" remote input, XLR microphone inputInput Impedance - Program: 20 kΩMaximum Input - Program: +14 dBuInput Impedance - EXT Mic: 2 kΩMaximum Gain - EXT Mic: +45 dBDim Attenuation: -6 to -80 dBOutput Connectors: 1/4" left/right outputs, 1/4" remote outputClip Level - 1/4" Outputs: +20 dBuOutput Impedance - ¼ Output: 225 ΩConstruction: 14-gauge steelSize (L x W x H): 4.88" x 3.63 x 2" (12.4cm x 9.2cm x5.1cm)Weight: 1.45 lb (0.66 kg)Conditions: For indoor use at temperatures between +15°C and +40°CPower Supply: 15VDC 400mA, center pole positive Radial Engineering StudioQ Studio Talkback with Built-In Mic, External Mic Input and Program Input.
