4. OPERATION - Front panel
Function Toggle switch
Top position "Operate":
One of the LEDs beneath the input selector is burning depending on the position of this
rotary switch
.
The LED above the function switch is off.
The HP 300 MK2 now is working in the normal two channel mode
Center position "Mute":
The LED above the function switch burns, the LEDs beneath the input selector
go out.
In this position the outputs of the preamp are muted. This position is recommended when
new units are to be connected or disconnected from the inputs of the HP 300 MK2 This
way, you avoid disturbances during the connection at the output of the preamplifier. The
amplifier is working at once after switching the function switch to the top position, in the
opposite to the stand by position of the mode switch. After deactivating the stand by
function, it needs always three minutes to operate.
Low position : "Bypass / AUX":
The LED "AUX" beneath the input selector
burns, independent from the input the rotary
switch is positioned. The LED above the function switch is also burning. In this position
the AUX input is switched directly to the output OUT 2 of the preamp, bypassing the
volume regulator and the line amp stage. This signal is also present on the XLR output in
true balanced mode.
This feature is very helpful if the two channel amplifiers and speakers supposed to be a
part of a multi channel system, normally the Front Left and Right amplifier / loudspeaker
channels. Therefore the HP 300 MK2 allows the user to combine two and multi channel
systems without disconnecting the power amplifier or the speakers. (see Chapter 6.)
IR-Sensor
For perfect operation of the remote control, the infrared receiver should not be covered.
Input-selector (rotary switch)
If one of the LED s beneath the input-selector is lightning (tape-switch up), the indicated
source can be recorded simultaneously throughout the REC-output (located at the rear
panel of the HP 300 MK2MKII) by tape etc.
