Floating Transformer-Balanced XLR Output for Maximum Isolation. 4 Independent Channels for 4 Keyboards, Drum Machine Outputs, etc. 3 IN/OUT Jacks per Channel for Convenient Loop-Thru.
LINT Mode Handles Signals to +34 dBv. GND/LIFT Switch Eliminates Hum and Buzz. Rack-mounted Uni-box Construction for Superior Protection and Shielding. Flush-mounted Switches and Connectors Resist Damage. Passive Design Requires No Batteries or Phantom Power.The DB4A provides four discrete direct-box channels in a convenient single space (1 3/4 , 44.45mm) rack-mounting package. Ideal for the multi-keyboardist, it is equally well suited to any application requiring the interface of unbalanced high-impedance equipment and balanced low-impedance mixer inputs. Unlike the traditional mic on the speaker approach, the direct approach delivers the clarity and punch that a modern sound demands. The full richness and character of the instruments is preserved because the distortion and coloration of speakers and microphones has been eliminated.
The versatile design of the DB4A allows easy integration with any high-quality audio system. Three parallel-connected IN/OUT jacks for unbalanced signals make patching in at virtually any stage of the signal path a simple task. Signals may be taken straight from the instruments (and effects devices) themselves, or from sub-mixer outputs (if you have to run out of mixer channels). Of course, multiple DB4As can be used when separate outputs from each instrument or effect are needed. The DB4As rugged 16gauge steel and aluminum Unibox construction enclosure is finished in a durable black texture powder coat finish with black anodized aluminum side channels.
Easy toread control graphics are incorporated into the Lexan® front and back panel overlays. Inside, DBT-P transformers combine superb audio quality with unsurpassed noise rejection. The DB4A can be mounted in any standard 19 (482.6mm) rack. All measurements made with 0 source feeding IN/OUT and 1.0 k load on all LO-Z OUTPUT to simulate typical "real world" instrument pick-up and mic preamp. Frequency Repsonse: 20 Hz - 20 kHz, ±.5% at -15 dBv output. 3 dB at approximately 85 kHz. >130 k at 1.0 kHz (INST mode).
>105 k at 10kHz (INST mode). Nominal source impedance is 20 k. Nominal source impedance is 0. Nominal output impedance is 1.0 k.Maximum Input Level at 50 HZ for 1% THD. +16 dBv (INST), +34 dBv (LINE) at 20 Hz.
+21 dBv (INST), +41 dBv (LINE) at 30 Hz. +26 dBv (INST), +46 dBv (LINE) at 50 Hz. The item "Pro Co DB4A 4 Channel Rack Mount Passive Direct Box DI, Great for keyboards" is in sale since Wednesday, May 28, 2014.
