Protections
Short Circuit Protection YES
functional Direct short at output
Amplifier should resume operation after short
circuit condition removal
Thermal Protection YES
functional
@1/8 max unclipped Power at
1.06 times the input voltage
Temperature rise in accessible metal parts
should not exceed 35K rise for domestic version
or 30K rise for European versions (refer to
requirements sheet).
DC Offset Protection YES
- DC present at Speaker Out leads
Design must insure no Offset at the speaker
output under any operating condition including
abnormal operation
Line Fuse Rating
USA-Domestic 3.15 Amps
3.15 Type-T or Slo Blo-250 V Internal fuse with UL/SEMKO rated holder
EU 2 Amps
2
Type-T or Slo Blo-250 V, Low
Breaking capacity Internal fuse with UL/SEMKO rated holder
Other Parameters/Notes:
1. Limiter circuit response must be clean sounding with no apparent pops, noises, or pumping.
2. Volume control should be at the input buffer stage in order to lessen the possibility of clipping the input section with highly dynamic audio material.
3. ALL SPECS SHOULD BE MEASURED AT NOMINAL LINE VOLTAGE.
