Roland VS-1680 owner manual Modeling various speakers Speaker Modeling, SpMod speaker modeling

New effects algorithms

Dither Off, 24–8bit

By adding a minute level of noise (dither), this smoothes the transition between playback audio and silence.

Level -80–+6dB

This adjusts the overall volume level of the sound that has passed through the limiter (Lmt).

Modeling various speakers (Speaker Modeling)

You can model the acoustical characteristics of a variety of speakers, ranging from high-level professional monitor speakers used in studios worldwide, to the speakers of small televisions or portable radios.

NOTE

Speaker modeling has been calibrated so that the optimal effect

will be obtained when Roland DS-90 powered monitors

are connected digitally. If you are using other speakers, you

may not be able to obtain the desired effect.

SpMod (speaker modeling)

Model

THRU, Super FLAT, Powered GenBlk, Powered E-Bas, Powered Mack, Small Cube, White Cone, White C +tissue, Small Radio, Small TV, Boom Box, BoomBox LoBoost

Select the speaker whose characteristics will be simulated (modeled).

THRU: Modeling will not be applied, and the sound will be output without change. Use this as a comparison with the speaker-modeled sounds.

Super FLAT: Modeling is used to compensate the DS-90, to produce an even flatter sound with a wider range.

Powered GenBlk: A widely used model of powered monitors (two-way type, with a woofer diameter of 170 mm (6-1/2 inches)).

Powered E-Bas:Powered monitors characterized by a bright tone.

Powered Mack: Powered monitors characterized by an extended low-frequency response.

Small Cube: Small full-range speakers widely used in recording studios.

White Cone: Sealed enclosure two-way speakers known for their white woofers and widely used in recording studios.

White C + tissue: A more mild sound, with tissue paper affixed over the tweeters of the above “White Cone” speakers.

Small Radio: Small pocket-type radio.

Small TV:Speakers built into a 14 inch size

television.

Boom Box: Radio cassette recorder.

BoomBox LoBoost:Radio cassette recorder with the Low Boost switched on.

Phase NRM, INV

Specifies the phase of the speakers.

NRM: Same phase as the input.

INV: Opposite phase of the input.

BCut (Bass-cut filter)

This removes unwanted low-frequency components, such as

pop noise.

Sw (Switch) Off, On

Switches the bass-cut filter on/off.

Freq (Frequency) Thru, 20–2,000Hz

Adjusts the cutoff frequency of the bass-cut filter.

LFT/HFT (Frequency trimmer)

Sw (Switch) Off, On

Turns the frequency trimmer on/off.

Gain -12–+12dB

For each trimmer, adjusts the gain (amount of boost/cut).

Freq (Frequency) 20–2,000Hz

Freq (Frequency) 1.0–20.0kHz

Set the center frequency of each trimmer.
