API 505 DI Direct Input (500 Series Module) Like the console-based API 205L, the 505-DI is specifically designed to accept a guitar, bass or keyboard direct input while minimizing any loading effect on Hi-Z instrument pickups. Additionally, the 505-DI's Gain Control is used to normalize an instrument's input level, up to a +4 dBu output level. API's unique TONE control reduces potential low end "mud" in the signal, while turning on the BRIGHT switch adds additional clarity if desired. The various combinations of TONE and BRIGHT controls can eliminate the need for any EQ on the instrument while recording, keeping the signal path short and pure. This minimal signal path eliminates the need to use a standard direct box, which many times still requires a mic input, equalizer, and a fader to get the signal to a recordable level. The 505-DI is capable of boosting any instrument to a hefty line level without additional amplifiers. Use of the 100K / 400K LOAD switch allows the tone of the pickup to be altered slightly, alternately brightening or darkening the high frequency content. When inserting an instrument with an internal preamp or a line level instrument such as a sampler or a keyboard, the 505-DI offers a 20 dB PAD switch to drop the level without loading, thereby retaining the integrity of the incoming signal.

It works especially well on acoustic guitars, giving them a much-needed sparkle and string definition when recording direct. I like this definition on DI bass too, for when I want to hear the string plucks. ...What I like best about the 505-DI is that it sport the full API sound and circuitry through and through -- op amps, transformer, and all." - Paul Vnuk, Jr. Specifications Number of Bands Two Filter Type Passive Shelf Filter Frequency Centers Low: 150 HzHigh: 8 kHz Input Impedance >380 K Ohms, Un-Balanced Output Impedance 75 Ohms, Transformer coupled, Balanced Nominal Levels -40 dBu to +20 dBu Clipping Level +30 dBu Frequency Response 0, -.4, 30 to 20 kHz Noise 98 dB below +10 dBm output, unweighted. 20-20 kHz Distortion THD: .01% (+4 dB @ 2 K) Connector 15 position .156 sp edge connector Power Consumption ±16 Volts DC, 130mA max at +24 dBu out Size 1.5" X 5.25" X 7" Deep Size (Shipping Box) 4.5" X 6.5" X 10.25" Actual Weight 1.41 lbs.
