1. FROM AMPLIFIER INPUT1 Automatic Standby function When you play a source the power of this unit turns on automatically by sensing audio signals input to this unit This unit turns into the standby mode automatically if the source being played is stopped or the low frequency input signal is cut off for several minutes This function will operate by sensing a certain level of low frequency input signal Its sensitivity is high in the HIGH position and low in the LOW position of the AUTO STANDBY switch In the HIGH position the power will turn on even with a low level of input signal but on the other hand this unit may not turn into the standby mode when there is an input signal even if its level is extremely low There may be a case that the power turns on unexpectedly by sensing noise from other appliances If it occurs set the AUTO STANDBY switch to the OFF or LOW position The level of low frequency input signal differs with each source and each different part on the same source So this function may not operate properly depending on some Sources This function is available only when the power of this unit is on by setting the STANDBY ON button to ON PHASE switch Normally this switch is to be set to the REV reverse position However according to your speaker systems or the listening condition there may be a case when better sound quality is obtained by setting this switch

10. ctive Servo Processing speakers reproduce the bass frequencies through an air woofer which is a port or opening in the speaker s cabinet This opening is used instead of and performs the functions of a woofer in a conventionally designed speaker system Thus signals oflow amplitude within the cabinet can according to the Helmholtz resonance theory be output from this opening as waves of great amplitude if the design is such that the size of the opening and the volume of the cabinet are in the correct proportion to satisfy a certain ratio In order to accomplish this moreover the amplitudes within the cabinet must be both precise and of sufficient power because these amplitudes must overcome the load presented by the air that exists within the cabinet Thus itis this problem that is resolved through the employment of a design in which the amplifier functions to supply special signals If the electrical resistance of the voice coil could be reduced to zero the movement of the speaker unit would become linear with respect to signal voltage and to accomplish this a special negative impedance output drive amplifier for subtracting output impedance of the amplifier is used High amplitude bass sound By employing negative impedance drive circuits the amplifier is able to generate precise low amplitude low frequency waves with superior damping characteristics and these waves are then radiated from the cabinet opening as hi
