The front panel will look similar to Figure 1 (above). The large display window normally indicates the current volume level and, whenever you change the input, it will briefly show the selected input label. On each side of the display window, are two

(2)buttons. On the right side is a large rotary volume control. As well, there are four buttons (4) directly below the window, for a total of eight (8) which are all described in detail below:

The “Standby” button disengages the input section from the rest of the P-7’s circuitry and turns off the digital display. However, when in “Standby” mode all audio circuitry remains powered up to help maintain optimal performance. When switching back from “Standby”, both the ‘input’ and volume settings are re-established from the previous listening session. The blue pilot LED will not be illuminated when the P-7is in “Standby” mode.

The “Display” button allows you to adjust the brightness of the large digital display window. It also provides you with the option of turning off the display. There are three (3) different levels of brightness; The default is medium. Pressing the “Display” button once will increase the level to medium. Pressing the button a second time will further increase the brightness to the highest setting. Pressing the “Display” button a third time returns the display to its default setting of medium.

If you want to turn the display off, press and hold the “Display” button for 2 seconds. When the display is turned off, it will still come back on for a short period of time whenever you press any of the buttons located on the front panel or the remote control, using the brightness level that was previously set; the display will automatically turn off again once you are done. To turn the display back on, simply press and hold the “Display” button for 2 seconds.

The “Monitor” button provides for a dedicated loop to be used with either a component that can record & playback (Cassette Deck, DAT, CD-Recorder, etc.) or a signal processor such as an equalizer. Pressing this button allows you to 1) monitor the recording as it occurs on the recording device or 2) engage the effects of the signal processor. The monitor component’s outputs must be connected to the P-7’s “Tape Monitor In” and its inputs must be connected to the P-7’s “Tape Monitor Out”. The monitor output level is fixed and independent of the P-7’s volume setting. The LED immediately to the right of this button will illuminate when the “Monitor” function is engaged.

The “Mute” button reduces your volume setting to zero. Pressing the “Mute” button a second time will return the output volume to its previous level. As well, adjusting the volume level while the “Mute” function is engaged will effectively defeat the muting function.
