4. OPERATIONS Setting the operating level The gain controls allow you to set the nominal operating level of the amplifier from 250mV to 2.5V for RCA inputs or 500mV to 5V for speaker level inputs. This wide adjustment range accommodates virtually any source unit brand. Improving bass sound The amplifiers feature a narrow-frequency band bass boost circuit (known as “high-Q”). The bass boost control acts much like an equalizer with switchable gain fixed at 50Hz. Use this control to

7. GLOSSARY Crossover: A device that limits the range of frequencies sent to a speaker or amplifier. dB: decibel, a measurement of the relative difference in power or intensity between two acoustic signals. Equalizer: Component that boosts or cuts sound signal frequencies to improve the quality of the sound. Gain control: gain is the amount of amplification (voltage, current or power) of an audio signal expressed in dB. Hz: Abbreviation for Hertz, a unit of frequency equal to one cycle
