Remote Control

7.1

VCA Level Control Inputs

Remote DC level control is available on these

three VCA (voltage controlled amplifier)

inputs. A VCA Gain block is first placed in any

input or output signal chain, then assigned to

a VCA input. Multiple VCA gain blocks can be

assigned to the same VCA input pin.
Ashly WR-1, WR-1.1, or WR-1.5 remotes can be

used for DC level control, or a custom control

can be made using a 10k Ohm potentiometer

and wired as shown. The dot indicates the

potentiometer clockwise position, full volume.

7.2

Trigger Logic Inputs

Eight programmable trigger inputs are

available for use with contact closure switches.

Triggered events are programmed in the

software Events screen, [Events>Triggered

Events> New event].
Triggered events include: A/B Source Select,

Action Sequence, Channel Mute, GPO Logic

Toggle, Mixer Mute, Paging, Pause/Resume

Schedules, Power On/Standby, and Preset

Toggle. Connecting a trigger input to the [G]

pin (ground) triggers the event.
Current trigger status can be viewed in the

[Settings>Panels>Rear Panel] screen.

7.3

GPO Logic Outputs

Two GPO (general

purpose output) pins

are available for driving

external device logic

inputs to effect a lighting

change, motorized

curtain, projector screen,

etc. GPO logic status can

be toggled as part of a

preset, or can be toggled

from a scheduled or triggered event.
Current logic High or Low status is viewed or set

in the [Settings>Panels>Rear Panel] screen.

7.4

Amp Fault Logic Outputs

An amplifier fault is any

condition that places the

amplifier into a protect

state. Faults can include

output overcurrent,

thermal, mains over-

voltage, internal mains

fuse, and output DC. If an

amplifier channel goes

into protect mode, the amp fault output pin for

that channel goes logic low.

7.5

Remote Standby

Standby mode puts the amplifier into a reduce

power state. Standby mode can be activated

via software, scheduled

or triggered events, or

with the standby pin

Euroblock connection.
Standby pin polarity

can be set in software

to Trigger on Low

or Trigger on High

[Settings>Panels>Rear Panel].
The Standby contact closure always has

priority over software or event driven standby.

7.6

Ashly Remotes

WR-1.0 and WR-1.1

The WR-1 and WR-1.1 are remote level

controllers used for DC level control inputs.

The WR-1.0 (dual potentiometer) and WR-1.1

(single potentiometer) mount to a standard

North America electrical wall box. The remote is
