These RANE Digital RPE 228d Programmable 2-Channel Equalizers are used but they appear to be in good condition. I purchased these units from University and the department contact assured me that they worked. I have not been able to personally test these units because I do not have the power adapters that go with them. Because I was assured that these items worked, they will each come with my FREE 30 day return/refund guarantee. You will be purchasing 1 at a time for the list price. I will be posting a product overview below. If you have any questions please do not hesitate to contact me. I encourage you to visit my profile page and take a look at my feedback from previous customers. Thank you for your interest in my items.
High Security Remote Control This equalizer is programmed by computer (PC compatible) via the RS-232 serial port. The computer may be removed after programming, or left connected to recall memories exclusively. As many as 16 units at a time may be daisy-chained. A recessed Default button on the rear panel recalls Memory 1 in case of computer failure Interpolating Constant-Q Filters 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. Low and Hi Cut Band limiting Filters Additional low and high cut filters have a wide adjustment range (Low Cut to 200 Hz and High Cut to 1 kHz). 16 Non-Volatile Memories No batteries are needed (EEPROM memory). The stored Memories may be recalled by remote switch contact closures (Memory Recall Port). The translation between the 8 closures and 16 Memories is programmable. Current settings are also non-volatile. Separate Input & Output Level Controls ±12 dB range on input and output in 1 dB steps, with settings stored in each Memory. Balanced Inputs & Cross-Coupled Outputs Euro block terminals are used for audio (and remote switch recall) connections. Shield ground connections are to the chassis. Firmware Updates via RW 232 The unit’s firmware may be replaced with new versions, uploaded from a computer through the serial port. Shipping: Size 4.5" x 20.3" x 13.75" Shipping Weight : 11 lb
