SAFETY AND PRECAUTIONS
The GOLDMUND SRM250 is an extremely high speed amplifier. Any bad ground connection can generate high frequency oscillation which is dangerous for tweeters.
It is also generally dangerous to run analog input cable and speaker cables in parallel for a long distance. If these cables are not of high quality or badly shielded, an “antenna-effect” can generate dangerous high-frequency oscillations.
❑Protection against DC
The GOLDMUND SRM250 is a DC-coupled amplifier. Without protection and if the associated analog preamplifier is badly designed or defective (often true for tube preamps and some 5 channel processors), the speakers could easily be damaged by amplified DC. The SRM250 protects itself from this danger via a feedback DC control loop that limits DC amplification. This protection circuit is totally transparent and has no sonic effect.
❑Protection against short-circuits
If one output is short-circuited by accident, the amplifier output has self-limiting protection to prevent the current becoming too high. Steps should be taken however, to avoid this happening over protracted periods as excessive heat build-up may still occur over time. In extreme cases, such mishandling could destroy the amplifier, which is not covered by the warranty.
There is no risk in leaving the speaker terminals unconnected when the amps are on.
