The API 505-DI module is a 500-series Direct input module taken the API 205L specifically designed for guitar, bass, or keyboards.
The purpose of the API 505-DI Module, minimises the risks of loading effect from Hi-Z instruments and normalises an instruments input level up to +4dBu to optimise the signal through the rest of your equipment.
Just like the API 205L, the API 505-DI features a unique Tone control which helps reduce Low Frequency muddiness in your signal and a Bright control which adds clarity, reducing the need to sculpt the sound with EQ at the recording stage.
The API 505-DI’s minimal signal path ensures the signal can be boosted to a high level without the need for an additional mic preamp and any additional distortion added by amplifiers. A 100K/400k Load switch lets you subtly brighten or darken the high frequency content. For instruments with internal preamps such as samplers and keyboards, a -20dB Pad lets you drop the level without sacrificing sound quality.
