Radio Design Labs ST-VP1

The ST-VP1 is part of a group of products in the STICK-ON series from Radio Design Labs. The durable bottom adhesive permits quick, permanent mounting nearly anywhere, or use it with RDL's racking accessories. The ST-VP1 offers the ultimate in quality preset mixing functions for voice-over and paging applications, with the big PLUS...you can put it right where you need it!

The exceptional audio quality together with the reasonable cost of the ST-VP1 make it equally useful in voice-over studio recording applications and in paging installations. The module is a line-level device with two inputs: MUSIC and VOICE. The MUSIC input normally feeds the output when no control option is selected. Two control options are available: FADE and CUT. When FADE is externally selected (pulled to ground), the Music source is faded down, and the Voice source is turned on. When the FADE terminal is released, the Voice source is turned off and the Music source fades back up. The fade rate and fade depth are both adjustable on multiturn trim pots. When the CUT terminal is selected (pulled to ground), the Music source is switched off and the Voice source is switched on. When the CUT terminal is released, the Voice source is switched off and the Music is restored. All switching and fading is accomplished electronically for noiseless operation.

The ST-VP1 can be wired to constantly feed a line-level input of a paging amplifier. A line-level music source feeds into the module. A line-level Voice source also feeds the module...this may be a telephone paging signal at line level, or a microphone which has been preamplified up to line level (See RDL STM-1, STM-2, STM-3 Microphone Preamplifiers). If the professional sound of music fading under the page is desired, the FADE terminal is used to select the page function. If a hard cut is desired to get people's attention for emergency pages, the CUT terminal can be used. Innovative systems can be created by cascading modules for prioritized messages. For example, two units could be used...one to operate the music fade for insertion of messages from a message repeater, with this module output feeding a second ST-VP1 used in the CUT mode for paging. In this way messages can be professionally mixed with background music, while attention-getting pages always take priority.

Many recording applications, such as narrations or commercial announcements, as well as on-air broadcast uses can be enhanced by uniform voice-over audio levels and fades. The superb audio clarity of the ST-VP1 makes it useful as the final mix device in this type studio. Using the ST-VP1 to mix the studio mic in after the studio mixer output can permit processing of the mic signal separate from the studio mixer. The ST-VP1 can be used together with other STICK-ON modules for creative control. Microphone signals can be tailored and controlled with modules such as the STM-2 Preamplifier, ST-EQ3 Equalizer and ST-CL1 Compressor/Limiter. Control of the ST-VP1 can be made convenient for announcers by using a lighted momentary push button together with an ST-LCR2 Alternate-Action relay for control. The ST-VP1 can be the heart of many innovative systems in quality voice recording and broadcasting!
