unbalanced.
Electrical Supply
Switched 110-220V +10%-20% at 50/60Hz. Power supply is designed
with extended low-voltage tolerance to meet road show requirements.
Size
482 x 44 x 228mm (19in x 1¾in x 9ins) overall.
Weight
4.5kg packed.
Options
Output Balancing
A separate output balancing unit is available providing full transformer
balanced and floating output sends to drive 600 ohm loads. These
custom made transformers allow excellent high current and voltage
drive signals that are required when using long multiway signal cables.
Security Panel
For applications requiring a recessed and blank front panel unit a
security cover kit is available which converts the standard FDS360 into
a fully tamper-proof rack mounting unit. All front panel controls are
hidden behind the blank steel panel.
