Desk box front panel
Chosen: option 3. The desk box's redesign adds a speaker-pair control: channel and speaker on C&K A10405RNCQ four-position rotary switches, the SH1122 OLED, and the Cooka CS19D32B volume encoder (short press power, long press OPT), all under Kaish Ø18 flat-top knobs. Three layouts for the new front panel, drawn to scale from the front on the 1455R1601BK's new-style panel (169.2 × 34.7). The rear panel stays as it is.

Option 1: two knobs, centred OLED, volume
The OLED stays centred; the speaker switch's clips clear its board by about 1 mm. The volume knob can't come in to mirror the speaker knob: the OLED board runs 14.7 mm past the window's right edge, so the volume encoder has to sit at +50 or further out; at +68.5 it mirrors the channel knob.
| Part | Centre / span (mm) | Part behind the panel | Clear of the OLED board (mm) |
|---|---|---|---|
| Channel | −68.5 | rotary switch, pins straight back | 27.0 |
| Speaker | −42.5 | rotary switch, pins straight back | 1.0 |
| Volume | +68.5 | encoder, pin bar down | 20.5 |
| OLED window | −26.8 to +26.8 | normal | board −34.0 to +41.5 |
Option 2: knobs on the left half, OLED on the right
The three knobs are 7.65 mm from the left edge, from each other and from the middle line. The OLED is mounted turned 180° so its board's long overhang points toward the middle; the right half has no room for it the other way. Even turned, a window centred on the right half (+42.3) would put the board's far corner into the case's corner screw boss, so the window sits at +39.5, 2.8 mm toward the middle.
| Part | Centre / span (mm) | Part behind the panel | Clear of the OLED board (mm) |
|---|---|---|---|
| Channel | −67.9 | rotary switch, pins straight back | 58.5 |
| Speaker | −42.3 | rotary switch, pins straight back | 32.8 |
| Volume | −16.6 | encoder, pin bar down | 8.2 |
| OLED window | +12.7 to +66.3 | turned 180° | board −2.0 to +73.5 |
Option 3 (chosen, front panel v4): OLED at the left, knobs on the right
Front panel v4 (2026-10-25). The OLED board sits as far left as the case's corner screw bosses allow (0.5 mm). The volume encoder's body is 1.5 mm from the case's side wall, and the speaker switch's clips 2 mm from the OLED board. The channel switch is midway between them, so the knob gaps are equal (12.4 mm). The volume encoder's pin bar points left, toward the channel switch: pointing down it would hit the corner screw boss.
| Part | Centre / span (mm) | Part behind the panel | Clear of the OLED board (mm) |
|---|---|---|---|
| Speaker | +10.8 | rotary switch, pins straight back | 2.0 |
| Channel | +41.1 | rotary switch, pins straight back | 32.4 |
| Volume | +71.5 | encoder, pin bar left | 63.7 |
| OLED window | −67.0 to −13.4 | normal | board −74.2 to +1.3 |
The rotary switches' pins point straight back, inside the Ø13 body; four clips on the body reach about 1 mm past it. The volume encoder's pin bar (six pins, reaching 11.5 mm from the shaft) points down unless noted, ending about 2 mm above the case floor. The OLED board overhangs its window 7.3 mm on one side and 14.7 mm on the other; turned 180° the overhangs swap, and the firmware turns the picture with it. Corner screws (±77.75, ±11.26) clear every knob by about 3 mm.
