CLOCK TEMPO Slider
The TEMPO slider located in the CLOCK section of the Clockworks
adjusts the master tempo or speed of the internal clock generator. When
the CLOCK toggle switch is set to INT (for internal), the TEMPO slider
sets the tempo that all four clock channels follow. TEMPO slider range: in
BPM: 50BPM – 2,400BPM; in Hz: 0.85Hz - 40Hz.
CLOCK LEVEL Slider
The LEVEL slider located in the CLOCK section of the Clockworks adjusts
the output level of the internal master clock sent to the CLOCK IN/OUT
jack. The 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.
