Additional 180 degree using the polarity switch. Limiter Range 0.5db steps -10dBv to -5dBv to -11dBv by changing barrier strip link. System Performance Noise -85dBm 20Hz -20kHz unweighted. Distortion less than 0.05%THD up to +20dBm limiter cancelled. Typically 0.005% THD +6dB output. General Insertion Points Channel sends. Output impedance 100 Ohm. Max load 10K Ohm at +20dBv. Band returns. Input impedance 10KOhm. Max level +20dBv 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.
