1. Pin 3 Negative Signal 13 Unbalanced Output These are the unbalanced RCA outputs to be used with amplifiers and active loudspeakers that have unbalanced RCA inputs You ll find the left channel output on top and the right channel output on the bottom The Snow White does not invert phase over these outputs 14 16 Unbalanced Inputs The RCA pairs INPUT 5 through INPUT 7 are the unbalanced analogue line inputs The top row of the inputs is the left channel and the bottom row for the right stereo channel These inputs can be used with all traditional line level sources such as Tuners CD Players Tape Deck etc Turntables will need a separate phono stage such as the TRIGON VANGUARD Il or ADVANCE to amplify the signal of the phono cartridge to a level which the SNOWWHITE II can accept 17 20 SPDIF Inputs To these jacks digital audio devices can be connected which emit an output signal in accordance with the SPDIF standard The amplifier can work up to 24 bit 192kHz 3 3 Remote Control The SNOWWHITE Il offers and optional IR Remote called the Director The Director is a system remote that can control multiple components t controls the following functions for the SNOWWHITE II preamplifier pP o Tt Ir de i On Off Standby used to turn the preamp on or off O i Display On Off used to turn the display on or off When switched off a small dot will be displayed behind the Input ps T L2. Turning the input selector knob clockwise will move to the Unity Gain option and turning it counter clockwise will exit the MODE menu 4 2 Initial Volume Level SNOWWHITE Il uses an electronic volume control system In addition to offering better performance over the conventional Potentiometer it also allows for special 10 features that have previously not been available One of these features is the ability to adjust the Initial volume level This is the volume level in which the preamplifier is set to any time it is turned on This design insures that if a high volume level was last used before the preamplifier was turned off that this level is not automatically selected when next turned on in an effort to protect your loudspeaker from potential damage The initial volume level can be set in the MODE menu To do so press the Input selector knob 1 and move to the fifth option to adjust the initial volume level Use the Volume Knob to set the desired initial volume level The selected value will automatically be saved as soon as another menu option is selected or on exiting the MODE menu Once finished adjusting initial volume level the preamplifier will automatically exit the MODE menu after approx 12 seconds or if the Input selector knob 1 is pressed 4 3 Display Brightness The brightness of the complete Display can be adjusted in 8 steps Turning the volume knob will adjust the display brightness in this menu
