The display shows the right channel spectrum or equalization level. The display of the spectrum or equalization level ib shown in the same way as for the left channel.
Note:
oFor this unit, even if this switch is switched to the "standby" position, there is still a slight power consumption of about 6 watts.
"Power-through" function
Discs, radio broadcasts, etc. can be heard even if the power of this unit is switched to standby, but without equalization effects. When using this feature, set the amplifier's selector to the source you want to hear, and, before switching "standby" this unit, press either the input selector buttons marked "source" or "tape".

Left-channel spectrum/equalization display
The display shows the left channel spectrum or equalization level. The spectrum is shown by using bars, and the equalization level is shown by using a dot-type (=) display. The "full range" area on the right side displays the combined level of all of the frequency bands. The "full range" display corresponds each setting of the spectrum level.
oLeft-channel level-control buttons
(EQ levelcontrol)
These buttons are used for adlustment of the equalization level of the lelt channel. When the button corresponding to the frequency to be adjusted is pressed, the equalization level of the left channel changes in 2-dB steps. lf a button is pressed and held, the equalization level of the left channel can be varied continuously throughout a maximum range of + 12 dB.

To enter an equalization curve into the memory, first press this butlon, and then, while the memory indicator is flashing (about 5 seconds), press one of the presetmemory buttons to complete the memorization of the equalization curve. (see page 7).
Preset-memory buttons (preset memory)
These buttons are used to preset the equalization curves into the memory. After curves have been preset into the memory, it is then possible to quickly and easily select the desired curve by simply pressing the corresponding button. There are six memory areas: three are for fixed-equalizationlevle memory, and three are for use by the user. (See page 6.)

Tape hiss can be effectively reduced by slightly raising the level of high frequency (above 2.5 kHz) sounds during tape deck recording, and then lowering them during playback.
