Step-by-step operating instructions

We've covered all of the basic controls and indicators of the Pictor. Here's how you use them to perform the

basic operations of turning the unit on, selecting a source, adjusting the sound, and turning the unit off.

STEP 1: Before making or changing any connections to the Pictor, turn off the master power switch on the

back of the power supply, and turn off the power amplifier(s).

STEP 2: To turn on the Pictor from the front panel, first make sure the power switch on the back of the unit is

on, and your power amplifier is powered off. Now touch the touchscreen. It will illuminate and a power but-

ton will appear onscreen. To power up the Pictor, press the onscreen Power button, the middle button under

the touchscreen or the Standby button on the remote

When you turn on the power, you will hear the Pictor's internal relays click as the unit goes into warmup

mode. The touchscreen will read Powering On. After about 10 seconds, an input screen will appear and the

most recently used input will be selected. Once Pictor and your source devices are fully powered up, it is safe

to turn on your power amplifier.

STEP 3: To change to a different input from the front panel, press the button under the Home icon. This will

bring up the input select screen. Push an onscreen button (XLR-1, RCA-1, etc.) to select the input you want.

The screen for that input will appear. Alternatively, you can scroll through the available inputs using the In-

put button on the remote. Enable playback on the chosen source device.

STEP 4: Adjust listening volume with the volume knob on the front of the unit or the volume up/down but-

tons on the remote. Note that the control is calibrated in negative decibels (-dB), reaching maximum volume

at 0.0 dB and minimum at -99.0 dB. Thus, when you turn the volume up (clockwise), the number on the front

display will decrease. When you turn the volume down (counterclockwise), the number will increase.

STEP 5: To adjust left-to-right balance, turn the balance knob. Counterclockwise shifts the balance to the left,

clockwise shifts it to the right. Or use the buttons on the remote; left shifts the balance to the left, right shifts to

right. The onscreen indicator will show you the balance setting in 0.1 dB increments.

STEP 6: To mute the sound, press the Mute button on the remote or the second button from the right under

the touchscreen (only available when the home and volume/balance screens are displayed). An X will appear

next to the speaker icon, and the volume indicator will flash. To unmute the system and restore sound, press

the Mute button on the remote or the button under the touchscreen.

STEP 7: You may wish to set a maximum output level to prevent damage to your speakers if the level is acci-

dentally turned up too high, and a minimum output level so that the Pictor always delivers an audible vol-

ume. To do this, adjust the Pictor's volume to the desired minimum or maximum level. Push the

multifunction button labeled Setup. Press either the Set Min or Set Max button, depending on which function

you want. Hit Apply to accept the setting, or Cancel to return to the original setting. To clear the setting, press

either CLR Min or CLR Max as appropriate, or press Default to clear both settings.

STEP 8: If you want to use the Pictor in a home theater system, in conjunction with a surround-sound proces-

sor, you should set up one input for home theater bypass. When you switch to this input, volume and balance

will be at fixed settings and your channel balance adjustments in the surround processor will be preserved. To

do this, first select the input you want to use for this function. Now adjust the volume on the Pictor to the de-

sired level. Push the multifunction button labeled Setup. Push the Set Min button, then the Set Max button,

then the Apply button. To clear these settings, press CLR Min then CLR Max, or press Default.

STEP 9: To turn the system off, stop playback on the source device. Hold the Standby button in the middle

under the LCD touchscreen or on the remote down for 5 seconds. The unit will enter cool-down mode for 10

seconds, during which no buttons will work. After cool-down mode finishes, you can turn the unit back on

again as described in Step 2 above.
