User manual RANE RP 228D DATASHEET

[. . . ] A recessed Default button on the rear panel recalls Memory 1 in case of computer failure. Each channel has 28 bands of 1/3-octave interpolating constant-Q filters for predictability and minimal interaction between bands. The boost/cut range is ±10 dB in 0. 5 dB steps. The digital filters are designed to match the previously available analog RPE 228. Additional low and high cut filters have a wide adjustment range (Low Cut to 200 Hz and High Cut to 1 kHz). [. . . ] These curves can then be sent to a unit or saved in a file. The software is operational even without an RPE 228d connected. The Rane RPD 1 may be used to control the RPE 228d from a remote location using a modem. The RPE 228d uses the same RW 232 commands as the RPE 228. The unit's firmware may be replaced with new versions, uploaded from a computer through the serial port.

No computer is required after initial setup. There are nine terminals--one is chassis ground, and the other eight are for Memories 1-8. Momentary connection of one of these eight terminals to ground causes both channels of the unit to recall a preset Memory. Multiple units may be controlled by connecting these terminals in parallel. Either momentary or latching switches may be used. Use of a latching switch results in a Memory recall upon power-up. The latching switch should only close one contact at a time. The translation between the eight closures and the 16 Memories is programmable. Architectural Specifications The programmable digital equalizer shall consist of two channels, each with 28 bands spaced on ISO centers from 31. 5 Hz to 16 kHz, and be 1/3-octave wide, all as specified elsewhere. The amplitude control range of each band shall be +10 dB and -10 dB, adjustable in 0. 5 dB steps. Each channel shall have adjustable low-cut and high-cut filters. The low-cut filter range shall be 10 Hz to 200 Hz in 10 Hz steps, or OFF. The high-cut filter range shall be 1 kHz to 20 kHz in 1 kHz steps, or OFF. [. . . ] The unit shall have certified compliance with FCC docket 20780 Part 15J for Class B computing devices, and EMCD 89/336/EEC. The 120 VAC model shall be powered from a UL listed, CSA certified remote power supply, and the 230 VAC model shall be powered from a remote power supply meeting LVD 73/23/EEC & EMCD 89/336/EEC standards. The 100 VAC model shall be built to JIS for Japan. The chassis shall be constructed entirely from cold-rolled steel. [. . . ]
