’s clock divider by moving the center of its DIVISOR slider to the
slider sets a given channel’s output pulse amplitude or level. The maximum
jack is controlled by its channel’s LEVEL slider. These jacks are mono/TS ¼”
–
maximum output pulse is 14Vpp. The pulse waveform ranges from 0V to
+14V, it does not go below 0V. As you bring the LEVEL slider down, the
amplitude decreases to 0V. See the section on the previous page entitled
HOW TO SET THE LEVEL CONTROL for help setting the CLOCK LEVEL
control.
CLOCK INT/EXT Switch
The CLOCK switch determines the source for the master clock sent to the
four individual channels. When set to INT, the master clock is generated
internally by the Clockworks (and set by the TEMPO slider). The internal
clock is also sent out the CLOCK IN/OUT jack when set to INT.
When the CLOCK switch is set to EXT (for external), the internal clock is shut
off and the Clockworks connects the external clock present at the CLOCK
IN/OUT jack to the four clock divider channels. If no clock is connected to
the CLOCK IN/OUT jack, the Clockworks TEMPO LED does not blink, it
remains in a static state. When set to EXT, the CLOCK LEVEL slider is
inactive. The CLOCK TEMPO slider adjusts the amplitude of the external
clock. We recommend you set TEMPO anywhere between its maximum and
middle slider positions when using external clock. The acceptable input
amplitude range for the external clock signal is 4Vpp to 15Vpp for a clock
that swings positive only or +/-2 Vpp to +/-7.5 Vpp for a bi-polar clock. The
maximum acceptable external clock frequency that yields full pulse amplitude
out of all four channels is 65 Hz. The output pulses drop in amplitude as the
clock frequency rises above 65 Hz.
CLOCK LED
The LED above the TEMPO slider blinks at the same rate as the master clock
signal whether the clock is generated internally or externally.
CLOCK IN/OUT Jack
When set to INT mode, the CLOCK IN/OUT jack is an output, the internally
generated clock pulses will be output from this jack. When set to EXT mode,
CLOCK IN/OUT is an input, connect your externally generated clock to this
jack.
18V Power Jack
Insert the output plug from the supplied 18VDC/500mA AC Adapter that
came with your Clockworks into the 18V power jack located at the front of
your Clockworks. The Clockworks’ power jack is center positive, requiring
18VDC with a minimum current rating of 300mA. The Clockworks can be
powered from a voltage as low as 15VDC but the maximum output pulse
amplitude will decrease and the maximum divisor, at the slider’s lowest
position, may increase to 9 or 10. We do not recommend powering the
Clockworks with voltages below 15VDC which may yield unpredictable
results.
