Adjustable lrequency bands and the effect of level adujustment
60 Hz: Lowering the level will cut the ventilation noise of a music hall, hum of electronic instruments, boomy bass, etc. Raising the level will reinforce the heavy bass part of a pipe organ or add depth to the bass sound. 150 Hz: Boosting or cutting the normal bass,
lnputs
Outputs
400 Hz: lncreasing or decreasing the power, spaciousness and warmth of the sound. 1 kHz: Providing more presence for vocals, and moving the sound forward or into the background. 2.4kHz: Lowering the level will reduce stridency, and raising will make the base sound brighter. 6 kHz: lncreasing or decreasing the brightness of the sound; for examble, raising the level will make the violin sound silky smooth. 14 kHz: Changing the general atmosphere rather than the sound itself. Raising the level will highlight the delicate quality of instrumental sound, and lowering will reduce high-frequency noise such as the resonant peak of a cartridge tape hiss, etc.
LINE lN: Phono jacks, 245 mV (-10 dBs), 50 kohms TAPE lN: Phono jacks, 245 mY (-10 dBs), 50 kohms LINE OUT: Phono jacks, 245 mV (-10 dBs), Load impedance: more than 10 kohms TAPE REC OUT: Phonojacks, 245 mY (-10 dBs), Load impedance: more than 10 kohms
