Just like the PREQ2 Dual Channel Strip, it includes a front panel \u00bc-inch (1-meg-ohm) Instrument Input jack that when used, automatically routes its signal to the input transformer and also disconnects the 48-volt phantom power if already turned on.<\/p>\n<p>The front panel continues with a \u00bc-inch Thru\/Output jack that provides an unbalanced, isolated and boosted \u00abduplicate\u00bb of either the low impedance microphone or the Instrument inputs. The Thru\/Output signal is capable of driving a long line out to guitar amps in the studio and\/or effects pedals effectively and without quality loss. Great for creating unique effects, you may \u00abre-amp\u00bb and externally process either the low impedance microphone input signal or any instrument directly connected to the PREQ2&#8217;s front panel \u00bc-inch input jack.<\/p>\n<p>The PREQ2-500 has an Equivalent Input Noise (EIN) level of -128dBu, +25dBU of headroom, plus the acclaimed AIR BAND\u00ae EQ with up to 9dB of boost at your choice of 2.5, 5, 10, 20 and 40-kHz frequencies.<\/p>\n<p>Microphone gain is continuously variable using a single, large control knob that is switchable between two gain ranges of either +20dB to +42dB for most recordings or +42dB to +71dB using the +25dB boost button. This higher microphone gain is noise-free and perfect for very quiet sources like Foley\/sound effects or low output, old vintage mics.<\/p>\n<p>The compact front panel finishes with push-button switches for +48-volt phantom power on\/off, -20dB attenuation pad, a 70Hz, 2nd order 12dB\/Oct high pass filter, phase or polarity reverse, and AIR BAND\u00ae EQ on\/off.<\/p>\n<p>EQUALIZATION<\/p>\n<p>    The 70Hz high pass filter activates a 2nd order, 12dB\/octave high pass filter.<br \/>\n    The Air Band\u00ae shelving allows selection of 2.5, 5, 10, 15, 20, and 40kHz frequency choices with its own control and up to 9dB of maximum boost.<\/p>\n<p>TECHNICAL SPECIFICATIONS<\/p>\n<p>    Max Gain 71dB<br \/>\n    Noise level at the lowest gain setting is -100dB. EIN is -128dB<br \/>\n    Balanced XLR output headroom is +25dBu<br \/>\n    The microphone transformer feeds a differential set of front-end Class A discrete transistors paired with a FET input operational amplifier.<br \/>\n    High and low gain push button switch. Low range: +20dB to +42dB. High range (gain +25 switch with green LED): +42dB to +71dB. Switchable -20dB pad<br \/>\n    +48-volt phantom power, switchable, with red LED.
