Cary Audio Design SLP 05 - Manual (Page 10)

CONTROLS
FRONT PANEL PREAMPLIFIER
1. POWER LED (blue)
The blue power LED will light to indicate that the 12 VDC voltage is applied to the input
and output selector PC boards. The PC boards control the operation of the SLP 05.
2. READY LED (red)
Indicates that the SLP 05 preamplifier has gone through the initial bias timing delay
and is now ready to operate. Generally this action will take about 60 to 90 second to
complete after initial turn on.
3. POWER SWITCH
This switch controls the main power relay control system in the external power supply.
Turning it to the ON position will power up the 5AR4 rectifier tube in the external power
supply while providing the DC filament voltage for the eight (8) 6SN7 vacuum tubes on
the SLP 05. You will notice this switch also lights the front panel meters on the power
supply.
4. SELECTOR
The selector switch controls the input, gold plated relays that route the appropriate rear
panel inputs to the volume control.
5. OPERATE/MUTE
This bat handle switch will either mute the output of the SLP 05 or allow the signal to
flow to the basic power amplifier in the system. In the MUTE position the external
hand held remote unit will take over the mute/operate function. In other words, the
default position for remote hand set operation is in the mute mode. If set to Operate, it
cancels the MUTE function in the remote handset.
