7 STRUCTURAL FEATURES

7.3 Main Control Knob

We have designed the main control knob located in the center of the front panel, focusing on easy handling and good appearance.

For the encoder, a 250-pulse magnetic encoder is adopted, which enables the pulses are multiplied by 4 using software to produce 1,000 pulses per revolution so that a user can tune to the desired frequency smoothly.

Each of the aluminum parts is machined with CNC (computerized numeric control) and treated with spin finish. We also paid careful attention to the color of the main control knob; we have colored the knob with a color alumite treatment.

We made samples repeatedly until the desired color was finalized. The alumite color is adjusted to match the rubber color of the knob ring and the paint color of the front panel in order to express the integration and massiveness of the entire panel.

Not only for the main control knob, easy handling was our priority when designing the sizes and locations of other controls (knobs and keys). We carefully studied the sizes and layout of the knobs so that a finger will not hit the adjacent knob when a user turns a knob.

Though the TS-590S has a relatively compact front panel as an HF transceiver, the controls are positioned for comfortable operation.
