They are all connected in parallel and can also be used as output jacks. 4 LEVEL control This control enables you to adjust the level of signal input from the INPUT/THRU connectors (3). 5 EQ control HIGH: Determines the level of the high frequency band (1.6 kHz and higher). Turn the control clockwise to boost and counterclockwise to cut over a range of ±3 dB. Setting the knob to the optimum position produces a flat frequency response. LOW: Determines the level of the low frequency band at a center frequency of 55 Hz. Turn the control clockwise to boost and counterclockwise to cut over a range of ±3 dB. Setting the knob to the optimum position produces a flat frequency response. 6 PEAK/LIMIT indicator This indicator lights up red if the output level is too high. In this case, lower the level using the LEVEL control (4) or lower the input level. 7 POWER indicator When you turn the power on, this indicator lights up green. 5
