APPLICATION SPOTLIGHT

In this week’s Application Spotlight, we describe an effective, easy to install, remote controlled mixer for audio systems in smaller to mid-sized sports arenas.? These smaller arenas are very popular today and can be found in many locations including high-schools, colleges, civic centers, event centers, Sheriff Department event facilities, equestrian centers, and more.

The key product is RDL’s FP-TPX3A Format-A Twisted Pair Remote Controlled Mixer.? This compact mixer is from our Flat-Pak Series of products which are easily mounted to any flat surface.? It’s also an RDL Format-A Receiver.?

If you’re not familiar, Format-A uses standard CATx (CAT5 or greater) twisted pair cable to distribute three channels of audio over three of the wire pairs (pairs A, B and C) and electrical power over the fourth pair.? One, two and three pair Sending and Receiving modules can be used, multiple modules can be daisy-chained, and the cable runs can be short or up to 3,000 feet (900 meters) long.?

The FP-TPX3A is the ideal choice where a user-accessible mixer must control the volume of multiple sources in a zone. Format-A Senders connect directly to the mixer, allowing each input to be balanced, unbalanced, mic level, line level or Bluetooth audio, depending on the Sending modules chosen. ?It features three input Gain Trimers and a dual-LED VU meter which displays the mixer’s output level. ?The output is mono and available on a single balanced detachable terminal block or on two unbalanced RCA jacks. The two jacks can accommodate either a mono or stereo input of a power amplifier.

Remote control of the mixer allows audio signals to be kept at a single equipment location. Audio is mixed by VCA circuits that are adjusted by control signals from the remote control. The FP-TPX3A is designed to mix three Format-A audio signals from pairs A, B and C. ?A detachable terminal block allows a LOCAL INPUT to be connected directly to pair C for accommodating, in example, a local paging or music source. This input may be used if no connected Sender is set to use pair C.

The remote controls connect directly to the FP-TPX3A through an RJ45 jack using standard CATx cable, which is color-coded light blue to distinguish it from standard Format-A jacks. ?The mixer provides power to the remote control. ?Either a two-channel remote control such as RDL’s D-RC2 and D-RC2M, or a three-channel remote control such as the D-RC3 and D-RC3M can be used.

In this system example, RDL’s Format-A Connector Plates and FP-TPX3A Remote Controlled Mixer are ideal for this hockey rink’s announcement system, which would work equally well for other types of sports arenas. The straightforward design makes this system easy to understand and operate for the timekeeper.

RDL D-TPS1A and D-TPS7A input plates located inside the timekeeper’s box send a local microphone and a line level audio source (Computer, media player, smart phone, or tablet,) to the first two channels of the FP-TPX3A Remote Controlled Mixer in the amplifier rack. The third mixer channel is fed from another D-TPS1A located near the ice, providing a microphone input close to the action. Installing the D-RC3M Remote Mixing Control within arm’s reach allows the timekeeper to easily adjust levels and mute any of the sources.

The FP-TPX3A incorporates an audio detector and timer that can be used to turn off the power amplifiers when the system is not being used, resulting in substantial energy savings. The mixer inputs and the remote control are all connected using common CATx cables.

RDL’s Format-A family of products offer studio-quality audio, extreme noise and hum rejection, incredible reliability, and ease of installation.? With over 80 models to choose from, the design possibilities are almost endless.?
