Description

The Pro48's innovative digital switching power supply significantly increases headroom and allows for less distortion while yielding a smooth, linear response extending from 20Hz to well above 100kHz resulting in natural, uncolored signal transfer. This superior performance makes the Pro48 an ideal candidate for use with today's battery powered active basses and acoustic guitars that tend to overload other direct boxes. The compact Pro48 is built road-ready with 14 gauge steel in our unique book-end design that provides protective zones around the switches and connectors. The internal welded I-beam construction assures outside stress will not torque the PC board thus ensuring longer product life. Exceptional sonic performance, great natural tone at an affordable price; the Radial Pro48 truly represents a breakthrough in value! The Radial Pro48... Blue is True! -High resolution active direct box -Increased dynamic range and headroom -48V phantom powered with digital switching -Compact, rugged book-end design -Ideal for active guitars and basses

Properties

Features & Specifications Circuit type: Active with proprietary phantom powered switching supply Input: ¼" - 220 kOhms Input pad: -15 dB Output: XLR-M - 600 Ohm, pin-2 hot Thruput: ¼" - w/mono merge function Frequency response: 20 z to 40 kHz Linear performance: +/- 0.12 dB 20 Hz to 20 kHz Power: 48V phantom w/LED indicator Construction: 14 gauge steel, baked enamel finish Size: 4.25"dx 2.75"wx 2.75"h (107 x 70 x 43mm) Weight: 1.1 lb (0.50 kg) The Radial Pro48 is a professional direct box that is equally useful for studio as it is for performance. It serves the purpose by converting the high input impedance of an instrument to the low input impedance of a microphone level signal. It also balances the signal to allow long runs upwards to 1000 feet (300 meters) without appreciable signal loss or noise. Unlike typical direct boxes that simply use phantom power to drive an internal buffer, the J48 actually converts phantom power from DC to AC, then uses a unique digital switching power supply to increase the internal working voltage in order to achieve much greater headroom. Because of this process, the active amplifier (buffer) is not constantly red lining. This means we do not have to trade off frequency response for dynamic range. The result is a response curve that starts at 10Hz and extends well above 100kHz where most other 'pro' direct boxes are barely able to achieve a response past 15kHz and are completely mud in the low end. This ensures the natural tone of the instrument is maintained without degradation. So what does this have to do with using the Pro48? Simply put - with the Pro48 active direct box you have less to worry about. Although the Pro48 is extremely easy to use, there is a ton of technology built inside that makes it so. Using the Pro48 1. Begin by making sure the PA system is turned down before connecting the Pro48. This practice will assure that transients from powering up the active circuit do not enter the sound system. This good safe approach will help keep those tweeters working for years! 2. Connect the ¼" cable from the instrument to the Pro48's input and the thru connector to the instrument amp or personal playback system. 3. Connect the XLR cable from the Pro48 to the mixer. Turn the 48V phantom power on. Pretty much today all mixers are equipped with 48V phantom powering. This ingenious system sends a DC signal back to the Pro48 that powers the internal amplifier that does not interfere with the AC audio signal path. 4. Turn the volume up on your mixer - slowly to a low level and test to make sure signal is present. If you encounter any buzz or hum, try lifting the ground. 5. You are now ready to test the audio. Begin playing. If you encounter any distortion, lower the source volume or hit the input pad. You are now good to go!
