I recently acquired two Bruel & Kjaer filters for my modular, the 1613 (passive octave filter) and 1616 (powered third octave filter). The 1613 works perfectly, but I have not been able to get the 1616 working.
The 1616 was missing the battery compartment for 3 1.5V batteries. Therefore, I have tried to hardwire a 5V power supply, but the power indicators of the module do nothing. Because of the compact design of the module, I am having difficulty tracing the power through the module.
Because of this, does anyone know where I can find a schematic of this module? Thanks in advance!
