PRODUCT OVERVIEW
Front Panel Overview
GAIN (VOLUME) CONTROL
The Gain (Volume) Control on the face of the TA1501C amplier controls the degree to which the
input signal is amplied. The gain level, combined with the level of the input signal, determines
the actual volume output.
CROSSOVER (X-OVER) CONTROL
The Crossover Control on the face of the TA1501C amplier controls the range of low-frequency
(bass) sound sent to the output device, i.e. transducer, speaker, etc. This control is only
functional when the Low Pass/Bypass Switch is in the “Low Pass” position. The range of low-
frequency sound controlled by this dial is 40 Hz to 400 Hz.
AUTO/ON SWITCH
The Auto/On Switch allows the user to place the amplier into either Auto On/Standby mode or
On.
When the switch is set to “Auto” and no input signal is received by the amplier, the amplier
stage will power down and go into Standby mode. Upon sensing an input signal, the amplier will
power on automatically.
When the switch is set to “On,” the amplier will remain powered on, regardless of whether an
input signal is present or not.
LOW PASS/BYPASS SWITCH
The Low Pass/Bypass Switch enables and disables the Crossover function and control dial
of the amplier. When the switch is in the “Low Pass” position, the amplier only passes low-
frequency sounds. When the switch is in the “Bypass” position, the amplier passes the full
range of audio frequencies.
POWER INDICATOR (LED)
The Power Indicator LED displays the power mode. If the LED is:
RED- The amplier is plugged into AC power and the power switch on the back of the •
amplier is switched to “On.” If the Auto/On switch is set to “Auto,” a red LED indicates no
audio input signal has been received by the amplier.
GREEN- The amplier is plugged into AC power and the power switch on the back of the •
amplier is switched to “On.” If the Auto/On switch is set to “Auto,” a green LED indicates an
audio input signal is being received by the amplier, or, if the Auto/On switch is set to “On,”
the amplier is on.
