FRONT PANEL CONTROLS AND THEIR FUNCTIONS
| The Front Panel illustration is provided on page 32. |
€ SPEAKERS selector switches: Allow you to select one or, by setting
both switches to ON, both of the speaker pairs connected to the -
A and B terminals.
@ METER switch: Activates the power peak meter. This display is
not illuminated when the METER switch is in the OFF position.
@ LEFT and RIGHT LEVEL controls: These give you independent
control over the power output levels to the L and R speakers.
This allows you to preset speaker balance for optimum stereo
imaging. These controls can also serve to protect speakers
with power handling capacity lower than this amplifier’s rated
output.
€ POWER switch and indicator: Pressing this switch turns power
on, causing the POWER indicator to light. To turn the unit off,
press again. |
@ PROTECTION indicator: Lights for several seconds after power
is turned on, showing that the internal protection circuitry is
currently activated. This mutes the output signal to the
speakers, preventing the loud noise otherwise heard when
switching on the amplifier. |
@ Power peak meter: Indicates the power output on a logarithmically
compressed scale from 0.06 to 900 watts, independently for the
left and right output channels. Readings are accurate for 8 ohm
speakers only.
