AM/ AUX a f— » POST 'S' FIGURE 1 — Location of Input Channel Board Modifications The Electro-Voice 8400 Series Mixers are high-pertormance/high-value consoles designed for fixed or portable professional sound reinforcement systems. Features and performance also make them appropriate for broadcasting and recording applications. All models have left, right, mono, monitor, auxiliary 1 and auxiliary 2 outputs, all with unbalanced and transformer isolated connections Transformer isolation reduces hum and noise caused by ground loops. GENERAL FEATURES • Equal headroom in all stages for optimum noise performance. • Gain-calibrated level controls for visual check of mixer stage gain. • Optimum circuit design to reduce harmonic and intermodulation distortion to inaudible levels • Transient performance not slew-rate or power-bandwidth limited under any operating conditions. 20-20,000 Hz. • Space-saving compact design with optimum tilt. • Six fluorescent bargraph meters calibrated for O dB = +4 dBm at transformer isolated outputs (-2 dBu unbalanced outputs). INPUT SECTION FEATURES • Separate microphone and line preamps and connectors, switch selectable. • 48-volt phantom power for microphone inputs. • Circuitry to accommodate input levels from speech with distant microphones to close miking of rock music. • Continuously variable input gain controls with 11 detents for quick and accurate resetting. • Preamplifiers with -129 dBu equivalent input noise, high gam and very low distortion. • Three-band EQ with switchable midrange center frequency Shelving frequencies are 100 Hz and 10 kHz; midrange center frequencies are 600 Hz and 3.5 kHz. • Three auxiliary send controls modifiable at each input for pre- or post-EQ or -fader. • Center detents for equalizer and pan controls. • Send and return jacks on each input, for insertion of external signal processing devices. • Pre-fader solo system modifiable to post-fader, with LED indicator and metering. SUBGROUP SECTION FEATURES • Fader, pan control, send/return jacks and solo switch for each subgroup. • Separate tape input with level and balance controls. • Assignable "talkback" input for house or stage communications. OUTPUT SECTION FEATURES • Independently adjustable mono output, plus stereo. • Stacking input jacks lor all buses, to link with other mixers. • Powerful headphone amp with level control, mono switch and solo interrupt. • Two effects-return inputs with level, pan and momtor-send controls. CONNECTIONS • All microphone...
