FCC Statements
1. Caution: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
2. Note: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
BAlAnCed
A 2-conductor (plus shield), low-impedance connection.
Balanced cables are the preferred method for hum-free
interconnection of a given sound system for their noise-
rejection characteristics. (Also see Unbalanced.)
CHAnnel
One of any number of signal paths in an audio circuit,
such as input channel, output channel, recording channel,
left channel, right channel, etc.
deCIBel (dB)
A term representing the ratio between different audio
levels. For example, a ratio of 1000:1 = 60 dB.
delAY
Like an echo, this effect duplicates the original signal,
then plays it back at a rate you control. The rate at which
these repeats occur is the “delay time.”
eQUAlIZATIOn
Electronic filters that adjust the level of certain
frequencies. Used for tone enhancement or to reduce
extraneous sounds. Two types of EQ shapes are Peak
and Shelving, described below.
IMPedAnCe
Resistance in an electrical circuit measured in Ohms (Ω).
Maintaining proper impedance (between amplifier and
speakers for example) is important to prevent damage to
the amp.
PeAK eQUAlIZeR COnTROl
Increase or decrease of a frequency range centered at a
specific point, resulting in an EQ curve that looks like a
hill (increase) or a valley (decrease). (Also see Shelving
Equalizer Control.)
SHelVInG eQUAlIZeR COnTROl
Increase or decrease of all frequencies above or below a
specific point. (Compare to Peak Equalizer Control.)
TRS (BAlAnCed)
Acronym for Tip-Ring-Sleeve — the three parts of a two-
conductor (plus shield) audio plug. TRS phone plugs are
often used for “balanced” connections.
TRS (UnBAlAnCed)
Another common TRS application is for “dual unbalanced”
connections, such as insert send/return jacks or stereo
Y-Cord. These are used for inserting an external processor
into a signal path. (See page 6 of this manual.)
TS
Acronym for Tip-Sleeve, the two parts of an unbalanced,
single-conductor (plus shield) phone plug. TS connectors
are sometimes called mono or unbalanced plugs or jacks.
UnBAlAnCed
A single-conductor (plus shield), high-impedance
connection. Most commonly used for instrument
connections and cable runs of less than 20 feet.
XlR
The three-pin connector universally used for balanced
audio connections. A balanced connection reduces outside
noise and interference. (See Balanced above.)
