BLN

BLN is a 4 channel audio level converter designed to interface line or "pro" audio levels to modular audio levels. It features 2 independent converters with 2 channels each.

Converter 1: Line level/Balanced to Modular Level

The inputs for the top converter are for converting -10dB or +4dB signal levels (balanced or unbalanced) to +/-5V modular levels. Each channel can be set individually for +4 or -10 using channel 1 and 2 of the DIP switched

Converter 2: Modular level to Balanced Lined

The inputs for the bottom to converters accept a +/-5V modular audio level and converts them to a BALANCED +4 dB or -10 dB audio level. Each channel can be set individually for +4 or -10 using channel 3 and 4 of the DIP switched.

For balanced signals, simply use a 3.5mm TRS to 1/4" TRS Cable or 3.5mm TRS to 3.5mm TRS cable with a 1/4" TRS adapter. Unbalanced signals should use a 3.5mm TS cable
