Guitar amp simulator

(Guitar amp modeling)

An effect that simulates the characteristics (distortion or tone) of
various well-known guitar amps to make an instrument sound as
though it were being played through that guitar amp. This system
uses Roland's proprietary Composite Object Sound Modeling
(COSM) technology.
COSM

High frequency damp

In reverb or repeated delay (echo), this is a function that causes the
high-frequency components of the sound to decay first. It is also
called "high damp." Since higher-frequency components tend to
decay more rapidly in naturally-occurring reverberation and echo,
adjusting the high damp allows you to produce a more natural-
sounding effect. When used in conjunction with Low Frequency
Damp, you can simulate the differing absorptive characteristics of
rooms with walls made of different materials.
Low frequency damp

High frequency trimmer

A parameter that allows fine adjustment of the high frequency gain.
HPF, High pass filter
A filter that passes only the portion of a signal that is above the
specific frequency. Also called a low cut filter. The input channels
of this system provide an HPF that is independent of the equalizer
and effects, allowing you to remove unwanted low-frequency
components of the signal, or to remove the "pop" noise that is
heard when someone blows into a mic.
A filter that allows frequencies above a specified cutoff frequency
to pass.
Hum canceler
An effect that erases hum (low-frequency noise that is caused by
things such as alternating current power supplies).
Impedance
The total resistance of an electrical circuit to an alternating voltage
such as audio, expressed in units of an Ohm (É ). When
transmitting a signal, the output impedance of the transmitting
device must match the input impedance of the receiving device. If
not, problems such as distortion, noise, and lowered signal level
can occur.
In place (SIP)
A solo function that lets you audition the signal after the channel
fader, EQ, and pan etc. (i.e., post fader). Also called stereo AFL
(After Fader Listen). On this system, using SIP (Solo In Place) will
affect the output signal of the main outputs. This means that SIP is
used mainly during rehearsal, and usually will not be used during
recording or during an actual sound-reinforcement event (concert
etc.).
Solo
Initialize
To restore the parameters of a device to their basic state.
Alternatively, to return all settings of a device to the factory settings
(which may not necessarily be the same as the basic settings). The
function provided by this system is the latter, and is called "Factory
Reset" in order to avoid confusion with the first.

Insertion effect

An effect that is used by inserting it directly into the signal path.
Examples of insertion effects include distortion, equalizer,
compressor, and wah. Normally these are used without mixing in
the original dry (direct) sound.

Insertion jack

A jack used to insert an external effect into the input section. On this
system, insertion jacks are provided on channels 1–6 and 11–16 of
the processor. The jacks are TRS type, and a splitter cable (such as
the Roland PCS-31) is used to connect the external effect. This
allows a single jack to both send and receive the signal.
TRS type
Install
To "attach" or "add." An example of usage would be "install an
effect expansion board." (In the context of personal computers, this
term mainly refers to the process of copying software onto an
internal hard disk etc. so that it can be used.)
Isolator
An effect that extracts (or eliminates) the sound of a specified
frequency band from the input signal. With a conventional
equalizer, some of the sound will still be heard even if the gain of a
frequency band is turned to the minimum setting, but with an
isolator the sound is completely eliminated.
Library
Settings for input channels, EQ, and effects that are provided for
various purposes. This system provides preset libraries that cannot
be erased, and user libraries that can be rewritten.
Limiter
An effect that works similarly to a compressor. When the input
signal rises beyond a specified level (threshold), a limiter instantly
lowers the gain to limit the output level. The degree of compression
is specified by the Ratio. In general, ratios of 1:10 or less are referred
to as compression, in distinction to limiting.

Lithium battery

A type of miniature battery. This system uses a button-type lithium
battery (CR2032) to power its clock function and to preserve certain
parameters. When the battery runs down, you can open the battery
lid located on the bottom panel of the console and replace it.
Load
On this system, "load" refers to the action of loading a complete set
of library settings from a memory card into the memory of the
console. This term is not used in reference to the action of obtaining
an individual library item, which is instead called "copying from a
library to a channel."
Library
Localization
The action of fixing the location in the stereo field from which a
sound is heard. Alternatively, the location itself. Also referred to as
"pan"; e.g., "pan the bass to the center of the mix."
