input impedance: 470kohm nominal input level: –20dbv output impedance: 4.7kohm nominal output level: –20dbv recommended load impedance: 50kohm or greater power requirements: 9vdc (center pin = negative); 40ma minimum features: • rate—this knob controls the rate at which the phase shifting occurs. the rate control knob alternately illuminates blue and red at the same rate as the phase shifting. • intensiity—this knob adjusts the intensity of the phasing effect. • frequency—this knob adjusts what frequencies are affected by the phasing action. fully counter-clockwise causes the bass frequencies to be affected most by the phasing action, fully clockwise causes the treble frequencies to be most affected by the phasing action. • bypass swiitch—a “true-bypass” of the phaser effect. turns the phasing effect on-off. • output jack—connect to the input of your amplifier (or other audio device). • input jack—plug your guitar (or other audio source) in here. un-plug the input plug from this jack to turn off the device and save power (very important) when not in use.
