-What to expect-
The quality of sound will depend on a good organ sound source; the PRO-145 will provide the
incredible rotary effect. The PRO-145 emulates a 147 type rotary speaker with both back covers
removed and the horn rotor diffuser removed. Sound will radiate approximately 50% front, 20%
each side and 10% out the back. As you listen to the front of the cabinet remember plenty of
sound is being “spun” around the room from the sides and back of the cabinet.
Classic rotary speakers have limited frequency response and are designed to work with and
compliment tone wheel organs. The PRO-145 has many adjustable parameters that work with
classic and modern digital organs to provide maximum versatility in sculpting your sound.
Guidelines for all adjustments are present here, but we encourage experimentation as you become
familiar with each controls range of effect.
-Control Panel-
The audio section of the panel has two identical ¼” inputs, 12AX7EH pre-amp gain, volume,
pre-amp mode control, bass, middle, treble, high cut, horn volume and subwoofer volume.
The rotor controls are small trim pots that are adjustable to preference and usually not changed.
Individual control of the horn and low rotor dynamics is provided.
¼” TRS balanced inputs – Both inputs are balanced with tip = + (plus), ring = - (minus), and
sleave ground. If your keyboard has a ¼” balanced output, using a ¼” TRS cable will greatly
