1 OVERVIEW 4 1.1 INTRODUCTION Thank you for purchasing the PreSonus EUREKA. PreSonus Audio Electronics has designed the EUREKA utilizing high-grade components to insure optimum performance for an infinite period of time. We believe the EUREKA to be an exceptional sounding unit and an except ional value.
OVERVIEW 5 chance of over-driving the i nput and avoiding distortion. • +22dBu Headroom. The EUREKA mic-pre has +22 dBu of headroom. This feature gives you wide dyna mic range and excellent transient response characteristics. • Saturation Control.
OVERVIEW 6 3-Band Parametric Equalizer . Total tonal control is what the Equalizer section provides. The EQ will let you fine tune the sound to suit your taste with exacting precision. • By pass Switch. A bypass switch is provided to audition the signal in an equalized version as compared to a direct unaffected signal.
2 CONTROLS & CONNECTIONS 7 2.1 FRONT PANEL BASIC LAYOUT The front panel of the EUREKA is divided into four sections – Preamplifier, Compressor, Equalizer and Master.
CONTROLS & CONNECTIONS 8 Compressor Section: • Level Control (Attack, Release, Ratio, Threshold, Gain) • Soft Knee Switch • Bypass Switch • Hi-pass Sidechain Filter Equalizer Section: • .
CONTROLS & CONNECTIONS 9 2.2 PREAMPLIFIER GAIN: Provides +52dB of gain for the microphone input and +44dB of gain for the instrument input. IMPEDANCE SELECTOR: Selects the amount of resi stance that is applied to the microphone input.
CONTROLS & CONNECTIONS 10 XLR connector wiring for Phantom Pow er Pin 1= GND Pin 2= +48V Pin3= +48V PAD: Engaging the Pad switch provides - 20dB of attenuation with the push of a button.
CONTROLS & CONNECTIONS 11 Basically, as you turn the Threshold knob counter-clockwise, the input signal is compressed. (If you have a ra tio setting of greater than 1:1.) RATIO: Sets the compression slope. This is defined as the output level versus the input level.
CONTROLS & CONNECTIONS 12 2.4 EQUALIZER The EQ is divided into three sections or bands (Low, Mid and High) Each band has the following controls: GAIN : Controls the amount of cut or boos t of the corresponding frequency. Each gain control offers +/-10dB of attenuation.
CONTROLS & CONNECTIONS 13 2.5 MASTER MASTER (LEVEL): This control adjusts the output level of the EUREKA. It functions as a master fader for the entire processing strip. It is useful for adjusting the overall output level up or down to match the optimum input level of a recorder, mixer, etc.
CONTROLS & CONNECTIONS 14 All Input and Output connectors are serv o balanced. XLR or ¼” TRS with the following wiring standard: XLR/TRS PIN 1 / Sleeve GND PIN 2/ Tip High (+) PIN 3/ Ring Low (-) INSERT: Return and Send connectors are provided for use in conjunction with audio process devices such as reve rbs, delays, de-essers, etc.
3 OPERA TION 15 3.1 MICROPHONES The Eureka works great with all types of microphones including dynamic, ribbon and condenser microphones. Dynamic microphones and ribbon microphones are generally lower output devices and require no external power source.
OPERATION 16 into the external processor, then ba ck into the EUREKA. The final, processed signal will be available at the EUREKA output connector. The Send and Return signal will be inserted after the microphone preamplifier, before the compressor. 3.
