INPUT SELECTION
The Boulder 1008 Phono Preamplifier provides inputs for 2 car-
tridges. These can be from one or more turntables. Only one of these
inputs can be used at a time.
Select an input by pressing one of the pushbuttons labeled “INPUT
1” and “INPUT 2”. The 1008 will immediately mute the outputs and
the MUTE indicator will be red for 3 seconds. After that time, the out-
put will be unmuted and the MUTE indicator will be off.
Anytime a different input is selected, the 1008 will similarly mute
for 3 seconds.
It is not recommended to select an input that has no cartridge con-
nected. Make connections to an input first and then select the input. If
it is necessary to have all inputs disconnected, then mute the preampli-
fier temporarily.
MONO
To enhance monaural recordings played with a stereo cartridge, it
is often desired to mix the left and right channels together to form a
true monaural signal. In the 1008 it is possible to do this by turning on
MONO mode.
Pressing the MONO pushbutton will place the 1008 into monaural
mode and the MONO indicator will be red.
To return to normal stereo operation, again press the MONO push-
button. The MONO indicator will be off.
