AN-2200
Description:
The STD-10K Passive Divider / Combiner is used to combine the unbalanced stereo output of the media player to mono for connection to an unbalanced mono input on the mixer. The STD-10K is a resistive branching network with four ports, each with RF filtering circuitry. Any port may be used as an input or an output. The impedance of each port on the STD-10K is a nominal 10 kΩ. STD Divider / Combiner products may be wired for EITHER balanced or unbalanced operation. Balanced and unbalanced wiring may not be mixed on a single module.
FOUR FREQUENCY AUDIO TEST TONE SELECTION
Selectable Audio Frequencies on aTechnician’s Workbench for Equipment Testing and Calibration
AN-2213
Description:
The ST-OSC2A and ST-OSC2B Dual Audio Oscillators are installed on this audio practitioner’s workbench to produce stable sine waves at four distinct frequencies. The RU-ASX4D stereo 4X1 Audio Switcher provides the technician with a convenient means of selecting any of the 4 available tones which are used for level calibration and frequency response checks. The combination of the ST-OSCA and ST-OSCB provides tones at 100 Hz, 400 Hz, 1 kHz and 10 kHz. The level of each tone is adjustable between OFF and +14 dBu and is accurately maintained by integral AGC circuits. The output may be connected to balanced or unbalanced loads.
DISTRIBUTED LINE LEVEL FROM STUDIO MIC PREAMP
Three Distributed Line-Level Outputs from a Single Microphone in a Voice-Over Studio
AN-2183
Description:
The STM-LDA3 Studio Quality Mic Preamp with Distributed Outputs is used in this voice-over studio to bring the microphone signal to line level and distribute it to several different pieces of equipment. Designed for use in applications such as broadcast, recording and professional sound reinforcement, the STM-LDA3 provides low-noise, low-distortion performance in a small, economical package. The 1200 Ω balanced input accepts a wide variety of microphone input levels from professional, low-impedance dynamic and condenser microphones without loading the microphone. A multi-turn trimmer provides for precise gain adjustment which is simplified with the inclusion of RDL’s unique Dual-LED VU meter. Each of the three low-impedance outputs may be connected to balanced or unbalanced loads.
AN-2164
Description:
RDL Format-A series twisted pair products simplify the distribution of stereo audio to multiple headphone monitors in the broadcast studio. A single (standard 4 pair) UTP cable run allows the TX-TPS3A to feed stereo audio and power to the D-HA1A Headphone Amplifiers. Up to six D-HA1A may be connected to one TX-TPS3A Audio Sender. In this system the Headphone Amplifiers are housed in DC-1G Desktop Chassis’. The all
