It is equipped with the RE-115 K mic input transformer and the proprietary API output transformer found in the 512c single mic pre and throughout the API product line. The unit has an internal 48-volt phantom power supply, which is switchable for each channel, as well as -20 dB pad switches that affect both the mic and Hi-Z instrument inputs, both located on the front panel. \u003c\/p\u003e    \u003cp\u003e   Another feature of the 3124+ is that it can provide up to 65 dB of gain to an output clip level of +28 dBu. Additionally, the Hi-Z front panel inputs feed directly to the op amps, which allow a low level input such as a guitar or bass to be amplified without a matching transformer or direct box. These Hi-Z inputs can take input levels as high as +20 dBu, making them perfect for keyboards and other high level devices. The mic preamp outputs are on rear panel male XLR connectors. \u003c\/p\u003e        \u003ch3 id=\"toc_1\"\u003e   TECHNICAL DETAILS: \u003c\/h3\u003e    \u003cp\u003e   \u003cstrong\u003eINPUT IMPEDANCE:\u003c\/strong\u003e \u003c\/p\u003e    \u003cul\u003e       \u003cli\u003e     1500 ohms Mic, 470 K ohms   \u003c\/li\u003e       \u003cli\u003e     Un-Balanced, HI-Z in Output Impedance: Less than 75 ohms Channel Outputs   \u003c\/li\u003e       \u003cli\u003e     Nominal Levels: XLR Channel Output +4 dBu   \u003c\/li\u003e     \u003c\/ul\u003e    \u003cp\u003e   \u003cstrong\u003eSTEREO OUTPUT LEVEL:\u003c\/strong\u003e \u003c\/p\u003e    \u003cul\u003e       \u003cli\u003e     Unbalanced: nominal -2   \u003c\/li\u003e       \u003cli\u003e     Balanced: +4   \u003c\/li\u003e       \u003cli\u003e     Clipping level: XLR Channel Output better than +28 dBm   \u003c\/li\u003e       \u003cli\u003e     Frequency response: +0, -5, 10 Hz to 20 kHz (-.5 at 10 Hz)   \u003c\/li\u003e       \u003cli\u003e     Noise EIN: -129 Mic, -125 Un-Bal.
