Operation:
The face of the preamp features two rotary knobs, three illuminated indicators and one IR
remote control input receiver (never illuminates). The indicators are, left to right: mute,
phase, and HT/BP (Home Theater Bypass). The left rotary knob is input select and the
right rotary knob is volume control. Power button is located on the top center of the
Ambrose One. Depress to turn on/off. The aesthetics of the Ambrose One are
intentionally spare and elegant.
When first powered on, the mute and HT/BP indicator and MWI logo will be illuminated.
The unit will remain in mute for approximately 45-seconds, allowing for tubes to
stabilize. The volume control will automatically return to the '0' position at this time.
When the unit is operational, mute indicator will no longer be lit, unless mute is selected
via remote. If unit is muted via remote, it will remain in mute and mute indicator will
remain illuminated until unit is 'unmuted' via remote or volume is changed via the
remote. When the unit powers up, the phase indicator will not be illuminated, indicating
that signal is phase correct, or non-inverted. If the phase button on the remote is selected,
the phase indicator will be illuminated and absolute phase of both channels will be
inverted.
When powering any system up, it is recommended as standard practice, to always turn on
preamplifier first and amplifier last. When shutting any system down, it is recommended
to turn off amplifier first and preamplifier last.
The Ambrose One includes remote volume, mute and absolute phase control, via the
included custom MWI remote control unit. Volume is controlled by depressing the
Volume '+' and '-' buttons. Mute is indicated by the 'mute' symbol and Phase is
indicated by the '' symbol. These buttons are labeled on the remote. Remote may be
used to mute/unmute, toggle phase and adjust volume up or down. While the remote
includes other buttons such as, PWR, STANDBY, INPUT, MON., BAL. and TRIG.,
these functions are not used for this product.
