Mackie D8B v5.1 User Manual

• Determines the change in output level as a

function of the change in input level, once the
signal level drops below the threshold. This is
sometimes called downward expansion. The ratio
control ranges from 1:1.0 to 1:inf. Thus, if the ratio
is 1:2, a decrease in input level of 10 dB results in
a 20 dB decrease in output level (assuming the
input is below the threshold level).

• Enables external MIDI triggering for the gate.
• This can be useful for gating drums based on a

sequenced MIDI drum pattern.

• To set up MIDI gate triggering:
1. Select MIDI Map from the Windows menu.
2. Select New MIDI Route from the Edit window.
3. Assign a MIDI note by selecting Note from the

MIDI Status drop-down menu.

4. Select Gate MIDI Trigger from the Parameter

column.

5. Send a MIDI note to the D8B from a sequencer or

other MIDI device. The Mode setting in the MIDI
Map determines when the gate opens and closes
(see “Creating a Route” on page 94).

• Gate MIDI Enable can also be turned on and off

via external MIDI note commands.

• Click the ACTIVE button to turn on the gate for

the selected channel.

• Click the MENU button to Open, Save, Reset,

Undo, Cut, Copy, and Paste a Gate patch.

• Each MEMory stores the most recent MEM A or

MEM B EQ settings made for the selected channel.

• Click either of these memory positions to instantly

recall the stored settings.

• Ideal for making quick A/B comparisons between

gate settings.

 Meter View and Meter Mode are not stored in

the MEM A or MEM B settings.

• Use the arrows on either side of the channel number

(or the arrow keys on the keyboard) to scroll up or
down through the D8B channels.

• Click in the “Chan. Select” window for a pull-down

of all the channels.

• This displays the channel name.
• Double-click on the name to highlight it, then type in

the new channel name (up to 16 characters). Press
Enter or click elsewhere to complete the operation.

• Assign the channel to the main L/R bus or any of

the 8 bus outputs.

• Assign the channel to a tape output.
• Highlight the desired numbers to send the channel

to one or many tape outputs.

• This is the most visual way to tell if a channel is

routed to several tape outputs.

• A channel can be assigned to more than one tape

out, but only the last one selected appears in the
channel’s OUT window (in the overview screen).

• No two channels can be assigned to the same tape

output. To sum channels to a tape output, assign
them to a bus, the route the bus to a tape out.

• Highlight PHASE to invert the channel polarity by

180 degrees.

• Use the on-screen knobs to adjust any of the aux

send levels.

• Press Control while clicking the Aux knob to set

Aux send level to unity gain.

• Click the PRE button directly below the Aux send

knob to toggle the individual Aux Pre/Post status.

• Click the OFF button directly below the Aux send

knob to toggle the individual channel Aux on and
off (mute).
