Description:

The low current consumption of STICK-ON modules allows multiple modules to be powered from a single supply. The ST-PD5U distributes power from any RDL current-limited switching power supply to up to five modules with a total current requirement of 2 amperes or less. RDL 24 Vdc switching power supplies (purchased separately) are available with current ratings of 500 mA, 1 A and 2 A. All meet ENERGY STAR Level V standards.

Description:

The RDL DS-SH1 Stereo Headphone Amplifier allows talent to adjust the level of their own headphones. In this example, the recording console is providing sub-mix feeds to each monitor location. The headphone amplifiers have individual volume controls and deliver more than 50 mW to either high or low impedance headphones. The DS-SH1 output is a durable metal ¼” (6.3 mm) headphone jack. The DS-SH1M is available with a mini-jack output.

Description:

The mixing of multiple phantom-powered mics is often required in various stage or public meeting room installations. The STD-150 mixes the mic signals equally and passes phantom voltage generated by the mic preamp back to each of the mics. Each mic should have the same gain and should operate from a wide range of phantom voltage, as there is a small phantom voltage loss through the STD-150. The STM-3 works well in most applications but for critical, low noise installations the FP-MP1 is recommended. The gain of the three microphones is set on the STM-3. If individual mic gain adjustment is desired, use the RDL FP-MX4 (4 channel ultra-low-noise mixer with switchable phantom and gain for each mic).

Description:

This system uses a digital audio distributor to route the venue audio out to multiple digital amplifiers. Any of the outputs of the HR-DDA4 can be switched to provide S/PDIF (coaxial or optical), AES/EBU, or AES3ID formats.

Description:

Audio monitor speaker signals often contain unwanted noise that is distracting to performers between musical selections or when the monitors are not in use. Examples include ambient pickup from live microphones or hum from instruments. During these periods when performers are not actively listening to the monitors, the RDL ST-GLA1 (use 2 for stereo as shown) mutes the audio signal to the monitor amplifier(s). The muting threshold is adjusted on the module to activate the audio for valid signal levels. The monitors will be muted at all other times. This application may be used in installations using either fixed or portable monitor speakers. It is ideal for church choir monitors or any performance area using stage monitors. The RDL TX-PA40D 40 W Stereo Audio Power Amplifier is shown in this system. RDL offers a wide range of power amplifiers for monitor and public address applications.

Description:

Speeches, government meetings, product announcements and other media events are occasions where a number of reporters in the electronic press require a high-quality audio feed from the event organizers. The recording equipment in use might require a mic, balanced line level or unbalanced line-level signal. It is critical that each feed is isolated so that if one feed is accidentally shorted or back-fed, no other feed will be affected nor will the public address system. This example uses RDL STICK-ONs® to provide isolated audio output signals driving a variety of audio jacks on a “Media Panel.” An RDL RU-MX4 Pro 4-Input Mixer is used as the audio source. The line-level source is distributed through an ST-DA3 Audio Distribution Amplifier to line-level outputs on RCA, 1/4¨ phone, and XLR jacks. The same source is padded down to mic level using an STP-1 Attenuator and distributed through an STM-DA3 Microphone Distribution Amplifier to the mic outputs. All jacks shown are on Decora® wall plates. These jacks are available in the RDL AMS series should a rack or tabletop mount be preferred. Distribution of video at these events can also be added using RDL composite and VGA/XGA distribution amplifiers.

Description:

This application shows a pair of ST-TC1 Telephone System Couplers used for handset communication in a theatre. The ST-TC1 provides “battery” for powering a standard telephone instrument, a circuit for detecting “off hook” condition, a transformer-coupled output, and DPDT relay contacts that switch when “off hook” is detected. These features may be used to develop a “silent ring” intercom system for use in stage, studio and house of worship environments where an audible ring is not acceptable. Each telephone instrument requires a single ST-TC1. A twisted pair cable connects audio between the two modules. Additional pairs carry the annunciation (lamp, flasher, etc.) actuation closure. The annunciation device is active whenever the opposite phone is “off hook”. Six conductors (3 pairs) are required to connect the two locations. Cat5 cable may be used in which case the fourth pair may be used to carry 24 Vdc power between modules if they are not co-located.

Description:

Audio monitor speaker signals often contain unwanted noise that is distracting to performers between musical selections or when the monitors are not in use. Examples include ambient pickup from live microphones or hum from instruments. During periods when it is desired to mute the monitors, users may manually turn them off using the RDL ST-SSR1 solid-state audio switch module (use 2 for stereo as shown). The RDL RT2 remote control may be mounted in any convenient location (such as podium or wall). The RT2 controls the ST-SSR1(s) to switch on and off the stage monitor feed as required. This application may be used to mute the audio inputs to power amplifiers feeding either fixed or portable monitor speakers. This application is ideal for church choir monitors or for any performance area using stage monitors. The RDL TX-PA40D 40 W Stereo Audio Power Amplifier is shown in this system. RDL offers a wide range of power amplifiers for monitor and public address applications.
