Hello,
Below are the specs for a TR35 VU panel meter...
Professional, high Class
dB : -20~+5dB
0dB=1.288V+/-10%
DCR= 650Ω, If=450uA
Lamp : White LED x1pcs ,10~20mA (has no resistor inside)
I don't quite understand the specs in respect to what they mean. For example if I put exactly 1.288V going in the meter, the dial will point to 0 dB? DCR and If are confusing me but I do get the Lamp section.
Thanks
