4 OPERATIONUSER MANUALTECTON POWER AMP SERIESP.74. Controls4.. Volume ControlA volume control with 4 notched settings controls the audio signal. Thesesettings have been selected to correspond to human hearing characteristics(logarithmically) and therefore guarantee an optimal range of settings for prac-tical applications. Each channel can be set individually except when operatingin mono modes whereby only channel A is active.Set the volume to zero before turning on the amplifier to prevent the occur-rence of sudden high volume levels which may cause damage to your hearingand/or the speakers.4..2 Gain SelectorA switch on the rear of the TECTON allows the maximum amplification attain-able to be set directly in the input stage.The TECTON amplifier has a 26 dB and 32 dBvoltage gain setting along with a ,4 V sensitivitysetting.4..3 Gain and Input SensitivityThe table shows input sensitivity per channel for a given gain and load.
