System Features
The Samson E62i, E31i and E30i Graphic Equalizers all utilize state-of-the-art technology
in audio signal processing. Here are some of their main features:
• In the E62i and E31i, 31 bands of equalization, with each frequency band
representing 1/3 of an octave in the 20 Hz to 20 kHz range; in the E30i, 15 bands of
equalization, with each frequency band representing 2/3 of an octave in the 25 Hz to
16 kHz range.
• Constant Q circuitry ensures that the bandwidth of the selected frequency area stays
the same even when approaching maximum boost or attenuation. As a result, phase
shifting and intermodulation distortion is greatly reduced, making for pristine sound.
• In the E62i and E31i, 6 or 12 dB of gain and attenuation for each of the frequency
bands, allowing both fine and coarse adjustment of the equalization curve. In the
E30i, 12 dB of gain and attenuation for each of the frequency bands
• Ultra-low noise circuity ensures superb audio fidelity.
• Switchable 80 Hz High Pass Filter (HPF) for removing rumble and floor noise.
• In the E62i and E3ii, a Cut Only control for fast, easy notched feedback removal.
• Electronically balanced inputs and outputs.
• In the E62i and E30i, dual channel operation for processing either a stereo signal or
two independent monophonic signals.
• Front panel hard-wired Bypass switches (with dedicated Bypass LEDs) allow the
equalization circuitry and output level control to be activated or deactivated.
• Level controls enable output signals to be attenuated or boosted for optimum
signal-to-noise ratio.
• Peak indicator LEDs light 5 dB prior to clipping.
• Relay power-on circuitry prevents speaker "thumps" when the unit is turned on.
• Internal power supply ensures reliability and trouble-free operation.
• Standard 19" rack design (the E62i takes just two rack spaces, while the E31i and
E30i require only a single rack space) for easy integratation into any traveling or fixed
installation audio system.
• Optional security cover kit prevents EQ settings from accidentally being altered.
• All-steel chassis makes the E62i / E31i / E30i eminently road-worthy.
