Aux In: A jack input socket for connecting an external audio device, usually using either a 1.4” jack or 3.5mm jack cable. Mostly used for playing music from another device (e.g. an MP3 player) through the amplifier.
Clipping: Clipping occurs when an amplifier is overdriven and attempts to process a signal beyond its maximum capability.
Compressor: A compressor is an effect used to narrow the dynamic range (the difference in volume between loud and soft) by compressing or “squashing” the sound.
DI output: DI stands for Direct Injection. A DI output is used to send a signal to another device, for example a mixing desk. A DI output usually requires an XLR cable.
Enhance control: The Enhance control is Eden’s proprietary EQ sweep that simultaneously boosts the very low bass, upper middle and high frequencies, while cutting the lower mid frequencies.
Equalisation (EQ): the process of altering the frequency response of an audio system by altering the levels of different frequencies. This process is sometimes referred to as ‘shaping’ the sound. The EQ settings affect how closely an amp reproduces the input sound from the guitar.
Frequency response: this is how the speaker responds to any changes within the EQ. A higher frequency response will give more clarity to the individual EQ that you are changing, rather than blending the EQ.
Gain: The factor by which power or voltage is increased in an amplifier.
Hertz (Hz): Hertz is a unit of frequency of change in state or cycle in a sound wave, specifically one cycle per second.
Impedance: The effective resistance of a circuit/component to alternating current. Measured in Ohms (Ω).
Ohm (Ω): Ohm is the unit used to measure impedance.
Ports: Tunnels cut into (or built into) a speaker cabinet that increase the efficiency of the speaker, boosting the low frequencies.
Tuner Output: A dedicated jack socket for connecting your amplifier to an external tuner.
Tweeter: A small speaker that is used to accentuate high frequencies.
Watts (W): Watts is a unit of power. It is used to quantify the potential power output of an amplifier, and the maximum power handing of a speaker/speaker cabinet.
Whizzer cone: A second, smaller speaker cone that helps to accentuate high frequencies.
