We understand how convoluted the market place may be, and how difficult it is to come to a good decision in regard to sound quality. We appreciate your research and hope you enjoy your purchase.” Many Thanks, Lukas A. Lipinski Executive Director 1. INTRODUCTION You have selected Lipinski equipment which hails from thirty years of recording experience of Mr. Andrew Lipinski and his devotion to state-ofthe-art sound. To achieve this sound in the L-609 Pre-amplifier, we eliminated all capacitors and Integrated Circuits from the signal path and created our own, Lipinski Square patented discrete class A technology. We also created transformer-like circuitry emulating an amorphous core transformer, albeit without unwanted, odd harmonic distortion. 2. UNPACKING Our product is carefully packed by us to maximize safety in transport. We advise that you unpack it on a soft, thick surface (carpet, fitted carpet, blanket etc) It helps to save all original packing materials and use them when you move the product.

FEATURES All discrete, class A patented circuitry No capacitors in the signal path No ICs in the signal path Microphone XLR or instrument DI high impedance inch input Precision rotary gain control 8 position LED Peak / VU meter, switchable inside 48 Volt phantom power Resistor-less, -20dB PAD, which skips one stage of amplification to maintain signal quality Transformerless / Transformer input mode - proprietary circuit emulating amorphous core transformer, eliminates unwanted distortion Minimal internal signal wiring Gain control is implemented in negative feedback loop, therefore it does not degrade dynamics Lipinski Sound Corporation| Confidential Copyright 2010 6 | P a g e 4. FRONT PANEL DESCRIPTION 1. 48V PHANTOM POWER This switch provides 48 Volts to power condenser microphones 2. PAD 20dB The PAD function provides 20dB attenuation of signal 3. MIC / GUITAR input selector The GUITAR switch enables high impedance instrument direct input 4. Transformer-less / Transformer- emulating (XFMR) microphone input 5. MIC / HI-Z input selector Input socket used to plug microphone (XLR) or electric guitar (1/4 inch jack) 6. LED (Peak or VU) meter Diodes indicate output level 7. GAIN CONTROL The gain control adjusts the voltage gain from 38dB to 73dB When PAD switch is on, it adjusts the voltage gain from 18dB to 53dB Lipinski Sound Corporation| Confidential Copyright 2010 7 | P a g e 5. QUICK GUIDE TO USING THE L-609 PREAMPLIFIER Mounting The L-609 Preamplifier requires a 500 Series rack. 1. First, turn off and unplug your rack frame. Make sure the slot you intend to use is clean and free of debris 2. Firmly and evenly push the L-609 Preamplifier into place until it is well situated in the card slot 3. Mount the L-609 front panel with two screws, to the 500 series rack Note: The screws are tight-fitting. Make sure to not cross the thread 4. Plug your 500 series rack back into the AC source, and power-up your rack Set up 1. Turn the gain fully counter-clockwise and check that phantom power is off. 2. Using shielded, low capacitance microphone cable, connect a microphone to the preamplifier and then turn on the phantom power switch if required. When sending a signal to a recorder that has fixed input levels, simply increase the gain until the optimum recording level is reached. 3. Careful! Turning the phantom power switch on or off, or the main power switch on or off can produce a large amplitude spike in the line output. Protect your ears, speakers, and equipment by being careful while the L-609 Preamplifier output is connected to another piece of equipment. 4. Enjoy the sound of Lipinski.

Otherwise instantaneous output level is measured. 7.
