Graphic EQ and effects

This chapter explains how to use the built-in graphic EQ and effects, and how

to perform remote control operations via the dedicated protocol to control an

external head amp (Yamaha AD8HR) from the LS9.

The LS9 lets you insert the built-in graphic EQ (subsequently abbreviated as “GEQ”) and effects

into the desired signal route to process the signals.

You can use two types of GEQ; 31 Band GEQ which lets you freely adjust thirty-one bands (fre-

quency regions), and Flex15GEQ which lets you adjust any fifteen of thirty-one bands. You can

also use 48 different effect types.

In order to use a GEQ or effect, you must mount the GEQ or effect in one of the eight virtual racks provided in the screen, and patch the input and output of that rack to the desired signal route. In other words, the operation is just as though you had installed a signal processor or effect device in an actual rack, and used patch cords to connect it. Only GEQ can be mounted in racks 1–4, and either GEQ or effects can be mounted in racks 5–8. [Figure 1]

Up to two channels of input and output can be used for each rack. (However if the “31 Band GEQ” is mounted in a rack, there will be only one channel each for input and output.) [Figure 2] shows the signal flow for the virtual racks.

About the virtual rack

This section explains how to mount a GEQ or effect in the virtual rack, and patch the input/output of the rack.

1

In the DISPLAY ACCESS section, press the

[RACK 1-4] key and [RACK 5-8] key simulta- neously to access the VIRTUAL RACK screen.

In the VIRTUAL RACK screen you can mount GEQ or effects, and make input/output settings.

The screen contains the following items.

1 GEQ/EFFECT field

In this field you can mount GEQ or effects in racks 1– 8, and edit the input/output patching for each rack.

B RACK button

This displays the RACK MOUNT popup window, where you can select an item to mount in the rack. Each of these buttons corresponds to the rack shown at the immediate right.

C SAFE button

This button switches Recall Safe on/off for the rack. Each of these buttons corresponds to the rack shown at the immediate right.

D INPUT button

This button displays the OUTPUT CH SELECT popup window, where you can select the input source for the rack.

E Virtual rack

This area shows eight virtual racks in which GEQ or effects can be mounted. Racks 1–4 are only for GEQ, and either GEQ or effects can be mounted in racks 5– 8. (However depending on the type of internal effect, some can be mounted only in rack 5 or 7.)

When you move the cursor to a virtual rack and press the [ENTER] key, the result will depend on whether a GEQ or effect is already mounted.

●If a GEQ/effect is already mounted in that rack

The RACK 1–RACK 8 screen will appear, allow- ing you to edit the parameters of the GEQ or effect.

●If the rack is vacant

The RACK MOUNTER popup window will appear, allowing you to select the GEQ or effect that will be mounted in the rack.

F OUTPUT button

This button displays the INPUT CH SELECT popup window, where you can select the output destination of the rack.

2

To mount a GEQ or effect in the rack, move

the cursor to the RACK button for that rack and press the [ENTER] key.

The RACK MOUNTER popup window will appear.

1 Rack number

This indicates the number of the selected rack.

B Virtual rack

This is the virtual rack in which you can mount a GEQ or effect.

Mounting a GEQ or effect in the vir-

tual rack

• If you press only the [RACK 1-4] key or the [RACK 5-8] key, the setting screen (RACK 1–RACK 8 screens) for the rack you operated most recently will appear. To ensure that you access the desired screen, hold down one of the keys and then press the other key.

• Input/output patching will be cleared if you change the item that is mounted or remove the mounted item.

HINT

• Be aware that if you remove a GEQ or effect that was mounted in a rack and close the window, all parameter set- tings for that GEQ or effect will be discarded. If you have not yet closed the window, you can recover the settings by mount- ing the same GEQ or effect once again.

NOTE

The LS9 lets you mount a GEQ in racks 1–8 and patch it to the insert-out/in of a channel. You can use the top panel faders and [ON] keys to operate the amount of boost/cut for each band.

The following two types of GEQ are provided.

●31 Band GEQ

This is a monaural 31-band GEQ. Each band is 1/3 octave wide, the adjustable boost/cut range is ±15 dB, and the amount of boost/cut for each of the thirty-one bands can be adjusted. If a 31 Band GEQ is mounted in a rack, one channel of input and output can be used for that rack.

●Flex15GEQ

This is a monaural 15-band GEQ. Each band is 1/3 octave wide, and the adjustable boost/cut range is ±15 dB. The Flex 15GEQ lets you adjust the boost/cut amount for any fifteen of the same bands as the thirty-one bands of the 31 Band GEQ. (Once you’ve used up fifteen bands of adjust- ment, you won’t be able to adjust the boost/cut amount of another band until you reset a previously-adjusted band to the flat setting.)

A rack for which the Flex15GEQ is selected will have two Flex15GEQ units (shown as “A” and “B” respectively) mounted in that rack, and will allow two channels of input and output. If you mount a Flex15GEQ in each rack, you’ll be able to use up to sixteen GEQ units simulta- neously.

The LS9’s GEQ units can be patched to the insert-in/out of any channel except the ST IN channels. Here’s how to insert a GEQ into the selected channel for use.

1

As described in steps 1–3 of “Mounting a

GEQ or effect in the virtual rack” (→ p. 158), mount a GEQ in a rack.

The GEQ/EFFECT field shows the approximate set- tings and input/output levels of the GEQ. A rack in which a Flex15GEQ is mounted will show informa- tion for two GEQ units (A and B).

• If you’re using a stereo source, you can mount a Flex15GEQ in one rack, or mount two 31 Band GEQ units in adjacent odd- numbered/even-numbered racks. This will let you link the two GEQ units later.

• If you select the Insert Out of a certain channel as the input source, the Insert In of that same channel will automatically be selected as the output destination for that rack. For details on Insert Out/In, refer to “Inserting an external device into a channel” (→ p. 101).

In the GEQ/EFFECT field, move the cursor

Switches the currently selected GEQ on/off.

B FLAT button

This returns all bands of the currently selected GEQ to 0 dB.

C INPUT button

This button displays the OUTPUT CH SELECT popup window, where you can select the input source of the rack. The operating procedure is the same as for

E GEQ LINK button

This button links adjacent GEQ units. In the case of a 31 band GEQ, the GEQ units in adjacent odd-num- bered/even-numbered racks will be linked. In the case of a Flex15GEQ, the GEQ(A) and GEQ(B) within the same rack will be linked.

If you want to link two GEQ units, turn on the GEQ LINK button.

If you’ve selected 31 Band GEQ for two adjacent odd- numbered/even-numbered racks, or if you’ve selected a Flex15GEQ, you can use the GEQ LINK button to link the two GEQ units. This is convenient when you want to process a stereo source through GEQ units with identical settings.

When you turn the GEQ LINK button on, a popup window like the following will appear. The popup window contains the following items.

1 RACK x→y button (“x” and “y” are the rack number, or the rack number and the alpha- betical characters A or B)

The parameters of “x” will be copied to “y,” and then linked.

B RACK y→x button

The parameters of “y” will be copied to “x,” and then linked.

C RESET BOTH button

The parameters of both will be initialized, and then linked.

D CANCEL button

Cancels the link and closes the popup window. To confirm the link, move the cursor to a button other than CANCEL, and press the [ENTER] key. When you link GEQ units, a symbol will appear in the GEQ/ EFFECT field to indicate the linked status.

• If you select the Insert In of a certain channel as the output source, the Insert Out of that same channel will automatically be selected as the input source for that rack.

HINT

• You can also access the RACK screen by pressing the [RACK 1-4] key or [RACK 5-8] key. By repeatedly pressing the [RACK 1-4] key you can access the RACK 1–4 screens, and by repeatedly pressing the [RACK 5-8] key you can access the RACK 5–8 screens and EXTERNAL HA screen.

• The RACK screens for the 31 Band GEQ and the Flex15GEQ are nearly identical. However, the Flex15GEQ individually dis- plays two GEQ units (A and B) mounted in a single rack.
