We recommend international customers select priority shipping. Buyer is responsible for paying import and customs fees. Hairball Audio, LLC HairballAudio.com New faceplate, same classic sound. We've given the Lola Mic Pre a facelift with a new faceplate, but have no fear NOTHING else has changed. Hairball Audio, LLC is proud to introduce the new “Lola” mic pre in 500 series format. The Lola maintains a completely differential signal path from input to output. The benefit to this topology is lower noise and a high CMRR. It also takes advantage of the excellent balance of the EA-10468 input transformer. In addition, because there are two op-amps in parallel, available output drive current is increased. This lowers output impedance; improving output transformer performance and increasing the maximum undistorted gain. In this regard it’s similar to running a single op-amp design on 24V rails. The gain stage provides 65 dB of clean gain in 4.5dB steps utilizing a Grayhill rotary switch. The 600ohm; Bourns t-pad on the output allows the user to fine tune the gain setting. There are three illuminated pushbutton switches to select phantom power, phase and line mode. Activating the relay controlled line mode flips the input transformer making it a step down input. This allows the user to use the Lola on line level material. A pad has not been included due to the low ratio and large adjustable gain of the Lola. A 1:1.75 ratio input means the Lola has a lowest gain setting of 15.5dB reducing the need for a pad. The DI accepts a 1/4 ” unbalanced cable. Inserting a cable activates a relay that controls DI/Mic in circuitry. The DI passes through 2 FET buffers creating a differential signal to feed the 10468 input. The light pipe LED meter has selectable VU and Peak metering. Though the VU mode is actually average metering (90% of RMS), it’s calibrated to VU metering with little effect on peak mode. 0dB on the meter scale represents +4 (1.23V) in VU mode. A simple resistor change allows the user to have 0dB equal to 0dB (0.775V) if preferred. Peak mode displays the peak value of the waveform in the same scale. The front panel and L bracket are made in the USA . As a nod to the original 10468 input transformer, the durable front panel is finished with a textured powder coat. The knobs are machined aluminum and have plenty of grip for the Grayhill rotary.
