CUT adjusts the high frequency response of the power amplifier. Since the DZ30 does not employ negative feedback (which
contributes to it’s open, complex response), this control behaves differently than a traditional presence control. As CUT is
turned clockwise, the tone becomes less bright. The most counterclockwise position is the brightest. Use this to control
sparkle and edge.
MASTER sets the overall volume of your amplifier. Unlike most master volume controls, this control is placed within the power
amplifier, between the phase inverter and the power tubes. This “post phase inverter master volume” retains the tone and feel
of a cranked amplifier much better than traditional master volumes. In addition, turning this control all the way clockwise
removes it completely from the circuit.
You can use the MASTER control to get the cranked sound of your Dizzy 30 at much more reasonable volumes. You may be
surprised how accurate the tone and sound remains with this control.
INDICATOR will illuminate when the DZ30 is powered by turning the front panel POWER toggle switch to the ON position. If
INDICATOR does not turn on, check your power cable connections, and then the MAINS fuse on the rear of the unit.
OPERATE / STANDBY applies high voltage to the vacuum tube anodes (and screen grids) during use of the DZ30. To ensure
long tube life, first power the unit on with the toggle switch in STANDBY position for approximately 30 seconds. Then place
switch upward to ON position to use the DZ30. With the toggle switch in the UP position, the DZ30 is in operational mode. In
the DOWN position, the DZ30 is in standby mode.
ON / OFF
two-way toggle switch powers the Dizzy 30 on and off. With the toggle switch in the UP position, the DZ30 is ON. In
the DOWN position, the DZ30 is OFF.
