1) Inputs / Outputs There are 3 inputs and 2 outputs to meet the needs of the vinyl lovers who own more than one turntable. You can easily change the inputs with the INPUT rotary switch on the front panel. The XLR balanced output is ready for the balanced preamplifier. If your preamplifier is balanced, we strongly recommend a balanced connection for an optimal performance. Inputs: 3 pairs / MM, MC1, MC2 ( RCA, unbalanced) Outputs: 1 pair / RCA unbalanced, 1 pair / XLR balanced 2) Switch-selectable gain setting The Oracle Temple PH 1000 phono stage is equipped with 6 different stages gain setting, by using this knob you will be able to meet many cartridges specifications. You will also be able to set the gain depending on the output from the cartridges from 40dB up to 60 dB. 3) Selectable load impedance MM Load Impedance Fixed at 47K Ohms for standard. For lower impedance, you can try via MC inputs and select 25-470 Ohms load impedance through the rotary switch on the front panel MC Load Impedance The 6 positions rotary switch will support the MC selection of different load impedance. You can select from 25 Ohms to 470 Ohms depending on the load impedance of the MC cartridge.
