Tip & How-To about Denon Audio Players & Recorders

Denon VPROT Problem.

I posted a question regarding a Denon RCD-M37 DAB, which after a repair to the sub power supply transformer, came up with VPROT after a few mins use. After very careful measurements I found that the -12Volt line coming from the power regulator board situated behind the mains transformer was measured at 10.5Volts. It is necessary to replace the LM7912 regulator. Whilst with this board out check soldering and all other components. Normal operation has now been restored. I hope this will help regards Paul R.

Hi can you tell me that impedence on JBL TLx4 speakers- i need to know if they are compatible with my denon RCD M37 dab player thanks

Is it JBL TLX 420 then its impedance is 4OHMS. You cant connect these speakers to denon rcd m 37, because its output impedence is 6 to 16 ohms.

Self-powered would work but it would have to run on full-range amplifier (from the speaker posts) or Line Level signal (from the OUT RCA jacks) because this unit has no Sub-specific output. It's no bigge as the sub would naturally discard the higher frequencies via its own amp's and speaker
