GLOSSARY OF TERMS
Term Denition
2U Rack Space With U (Unit), being a standard unit of measurement for audio/video racking
systems, a 2U rack is a standard rack that occupies 2 units within the rack
system. A 2U rack is 3.5 inches (88.9 mm) high.
Audio Input/Output Connectors Audio connectors on the amplier that receive or transmit the main signal.
Auto/On Switch The switch under the Gain Control that allows the user to place the amplier
into either Auto On/Standby mode or On.
When the switch is set to “Auto” and no input signal is received by the
amplier, the amplier will go into Standby mode. Upon sensing an input
signal, the amplier will power on automatically.
When the switch is set to “On,” the amplier will remain powered on,
regardless of whether an input signal is present or not.
Automatic Balancing System Included in some Home Theater Surround-Sound Receivers, this feature
uses microphones to measure room sound levels in order to properly
balance low, mid, and high level sound output from the receiver.
AWG Abbreviation for American Wire Gauge. Commonly used to designate wire
size. The smaller the AWG number, the larger the wire size.
Crossover (X-Over) Control The control on the face of the TA1501C amplier that controls the range
of low-frequency (bass) sound sent to the output device, i.e. transducer,
speaker, etc. This dial is only functional when the Low Pass/Bypass Switch
under the control is set to “Low Pass.” The range of low-frequency sound
that is controlled by this dial is 40 Hz to 400 Hz.
Gain Control The control on the face of the TA1501C amplier that controls the degree to
which the input signal is amplied. The gain level, combined with the level of
the input signal, determines the actual volume output.
High/Low Input Signal Switch A switch on the TA1501C that allows the user to use 1 V RMS or 316 mV
RMS inputs. Examples include a home theater receiver (“High” Level) vs. an
MP3 player (“Low” Level).
IEC-601 Connector An adaptable AC connector that allows users to connect IEC-601 compatible
AC cords to the amplier. This type of connector is especially benecial for
international compatibility.
