The D SERIES-HA1A is a two pair receiver and audio headphone amplifier compatible with RDL Format A twisted pair products. Each -HA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack fed from a Format-A sender. The left and right audio signals received on pairs B and C of the twisted pair cable are amplified and fed to the left and right channels of the output 3.5 mm Mini-jack.
The front panel provides the headphone output jack and a single-turn user volume control. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. The audio input circuits feature very high common mode rejection and a high quality stereo headphone amplifier for superior audio fidelity and low-noise performance.
The -HA1A is ideally suited to guest room installations with bedside and restroom listening stations. The input is fully compatible with all RDL Format-A senders.
The -HA1A is equipped with two Format-A RJ45 jacks. Either jack may be used as the input. The other RJ45 may be used to connect an additional -HA1A or other Format-A receiver.
Installation is simple and economical. Standard twisted pair cable is used to connect a Format A sender to the -HA1A.
RDL FORMAT-A features superior audio performance that rivals or exceeds shielded wiring. Design simplicity, ease of installation, unsurpassed flexibility, automatic fused power, exceptional hum rejection, low noise, and low distortion provide designers and installers the optimum choice in economical twisted pair products.

D Series products are user controls, indicators and connection plates that are compatible with Decora® style mounting. D Series modules and jacks connect directly to a variety of active RDL modules in multiple product series and are compatible with many OEM products. Products in this series may be active or passive. All D Series front panels are constructed of stainless or carbon steel for durability, shielding and static protection. Stainless steel models feature a brushed finish with direct lettering. Painted models are finished with a reverse-printed front-panel polycarbonate laminate which provides an attractive, durable finished appearance.
Connector plates offer pass-thru jacks or rear-panel solder terminals. Transformer-isolated connector modules are equipped with a shielded enclosure and a rear-panel terminal block.
Active models include remote controls to provide source selection, routing, level control, muting, source or level LED indication and more.
The depth of D Series products is sufficiently shallow to permit mounting not only in standard North American electrical boxes but also in RDL wall boxes designed to fit in narrow walls used in international installations. RDL also offers a variety of related accessories for wall mounting, surface mounting and desktop chassis mounting of D Series products, as well as matching metal trim plates.
Attractive styling, ease of installation, long-life pushbuttons, high quality connectors and worldwide mounting possibilities make D Series products a preferred long-term resource for system design solutions. D-SERIES modules are designed and manufactured in the U.S.A.
