RDP “2”  STEREO 35 Watt – Serie of Digital Audio Players Class “D” – HIGH EFFICIENCY

Like the RDP series “2” Mono digital audio player (see previous page), the RDP series “2” Stereo player is equipped with a new, high-efficiency Class-D audio amplifier.  Thanks to the new amplifier, the batteries in the RDP “2” 35 Watt Stereo unit have a longer life (at moderate/average volume), and a radiator is no longer needed. Stereo players allow two speakers or horn diffusers to be used (up to 4 with the RDP 35 Watt Stereo model).  When playing a single bird call, the same call is played back on both channels, and the two speakers may be pointed in different directions. When playing back two (mixed) calls, a different call is played on each speaker.

N.B. Stereo players can be connected to only one speaker, but the “mixer” function is not available with this setup. To avoid damage to the players, the two outputs of the amplifier (AP250) must not be connected to a single speaker. Each unit is thoroughly checked and tested before sale.

The originality of Plurifon products is guaranteed by the holographic anti-counterfeiting label “Original”.

Type approved in compliance with EC standards.

 

Main technical features:

• Mixer function for simultaneous playback of any 2 tracks stored on the Mini-Card “2”
• Fully remote controllable
• Direct access to functions from keyboard
• Balance function for setting the volume of one call higher than the other
• Pause function (II) interrupts playback at any point and resumes play from the same point
• Display shows track or tracks currently being played, volume level, balance setting, pause status, timer count and a “no Mini-Card “2” inserted” warning
• LED battery level indicator
• Rapidly replaceable Mini-Card “2”
• Timer-controlled activation/deactivation
• Separate battery pack
• FM radio receiver function
• Headphone socket for listening to bird calls or FM radio with stereo headphones
• A-B function allows user to play back a selected portion of a call (or calls)
• Self-protected against accidental inversion of polarity. However, special attention must be paid to the external connection, since the circuit that prevents +/- polarity inversion does not offer 100% protection
