Installation BEFORE SWITCHING ON POWER SUPPLY AND PQ, THE PQ MUST BE CONNECTED TO Setting the appropriate supply voltage THE POWER SUPPLY WITH THE SUPPLIED MULTICORE LEAD. PAY ATTENTION TO A The appropriate supply voltage (115 V/230 V) must be set on the rear panel of the SECURE CONNECTION. external power supply. The fuse block (left from the power cord socket) can be The PQ and the external power supply should be situated away from heat sources inserted in two positions to meet your country

Key Functions Motorized potentiometers Bandwidth All of the PQ‘s potentiometers are motorized to accommodate the channel link and Bandwidth is adjustable between 0.1 and 3.7 Q in proportional Q mode and between unit link functions. The adjustment range of the Frequency, Bandwidth and Amplitude 0.9 and 15 Q in constant Q mode. The extremely high maximum bandwidth in constant potentiometers is evenly dispersed throughout the 300-degree movement area, Q mode enables tight, selective control in p
