Ahuja ADP 30R Recorder With USB&Bluetooth

Ahuja ADP-30R Recorder with USB and Bluetooth

The Ahuja ADP-30R is a digital MP3 player and recorder built for public address work, where the same unit has to play programme material into a PA system and capture what is said through it. It plays MP3 files from USB drives, SD cards and MMC cards, records to its connected media, and adds Bluetooth playback for wireless streaming from a phone or laptop. Ahuja publishes the core figures for this model in its catalogue, and those are the figures used here: a 200mV record input, a 200mV output into 600 ohms, a 20Hz to 20,000Hz frequency response within plus or minus 1dB, and operation from AC mains or a 12V DC supply.

In practice, a unit of this type sits at the front of an Ahuja mixer amplifier installation in a school, office, house of worship, factory or function venue. Announcements, prayers, anthems, bell signals and background music can be loaded onto a card or pen drive once and played back on demand, while speeches, meetings and programmes passing through the system can be recorded for archiving or later replay. Bluetooth covers the informal cases: a phone handed to the unit at an event, or music streamed from a laptop without running a cable across the room.

Recording for the record

The record side is what separates the ADP-30R from a simple media player. Feed it a line-level signal from a mixer or mixer amplifier through the 200mV record input and it captures the programme onto the inserted media in MP3 form, ready to be copied to a computer over USB media or played straight back through the system. That suits minutes of meetings, recordings of lectures and sermons, and archives of functions and ceremonies that institutions are often asked to produce later.

Made to live with PA equipment

The output level of 200mV into 600 ohms is a standard line-level feed, so the ADP-30R connects to the auxiliary or line input of Ahuja mixer amplifiers and other PA electronics without level-matching problems. Dual power operation, AC mains plus 12V DC, means the unit keeps working in the DC-backed installations common in Indian PA setups, where announcements must continue during a power cut. At W152 x H81 x D165mm and 1.20kg, it is a compact shelf or rack-side unit rather than a full-width component, which makes it easy to add to an existing amplifier stack.

Everyday playback, three media types plus Bluetooth

USB pen drives, SD cards and MMC cards cover the media most venues already have, and files can be prepared on any computer and carried to the unit. Bluetooth adds a fourth, cable-free source for ad-hoc playback. Together they make the ADP-30R a practical single box for scheduled announcements, recorded programme material and impromptu music in institutional sound systems.

If your PA installation needs one compact unit that records proceedings and handles USB, card and Bluetooth playback into a mixer amplifier, the Ahuja ADP-30R is built for exactly that job.
