17. System/ Remote
Go to Frame/System/Remote.
Remote features of the Reverb TwentyFour can be accessed through an external
user-supplied interface connected to the rear panel GPIO port (see page 43 for
details of the GPIO interface).
The Remote page of the TC Icon software has 3 main sections as follows:
• GPI – setup, choose, and enable dierent scene presets for remote recall.
This may be used for quickly changing of the acoustics by changing the
decay time in a venue. An external switch box can be made so the venue
technicians have 3 buttons – one for each of 3 user scene presets that have
dierent decay times. In this way you can select a decay time for the venue
that ts the evening's concert type.
• Cal – calibrate the operation of the external equipment.
• GPO – this can be used if required, to setup operation of external LEDs.
17.1 Remote – GPI 1 – Scene Recall section
• GPI input 1 can be used for User Scene preset recall (see “Library – Recall
page” on page 21). Please note that the Icon user interface is locked when
GPI is used for control.
Enable button
• Use this button to enable the GPI 1 input for User Scene Recall.
Current Scene Status eld
• The Current Scene status eld shows the name of the currently active Scene
preset. The currently active Scene will be shown here wether it has been
selected via GPI or not. The name shown here is identical to that shown on
the Library – Recall – Scene page as “Current” and on top of the Frame –
Routing page. When GPI is disabled, “-“ is shown.
Function parameter
• Use the Function parameter to dene the scope of the GPI recall feature. The
available GPI recall modes that you can set using the Preset Recall Function
parameter are:
• O setting – No Preset Recall using GPI.
• 2 Presets – Select one of two Presets using GPI1. Select the Preset Bank
using the Scene Bank parameter.
• 3 Presets – Select one of three Presets using GPI1. Select the Preset
Bank using the Scene Bank parameter. For a description of the “Idle”
state, see “Idle state” below.
• 4 Presets – Select one of four Presets using GPI1. Select the Preset Bank
using the Scene Bank parameter.
• 7 Presets – Select one of seven Presets using GPI1. Select the Preset
Bank using the Scene Bank parameter.
• 8 Presets – Select one of eight Presets using GPI1. Select the Preset
Bank using the Scene Bank parameter.
• 3 Presets DUAL – Select one of three Presets using GPI1 and GPI2.
This mode uses simple binary inputs on GPI1 and GPI2 – i.e. 00, 01, 10
and 11. Select the Preset Bank using the Scene Bank parameter.
• 4 Presets DUAL – Select one of four Presets using GPI1 and GPI2.
This mode uses simple binary inputs on GPI1 and GPI2 – i.e. 00, 01, 10
and 11. Select the Preset Bank using the Scene Bank parameter.
• 15 Presets DUAL – Select one of fteen Presets using GPI1 and GPI2.
This mode uses 8-state on GPI1 and binary on GPI2. In this mode, the
Scene Presets are always recalled from two consecutive banks – e.g.
Bank 1 and Bank 2. Select the Preset Bank pairs (1+2, 3+4 etc.) using
the Scene Bank parameter.
• 16 Presets DUAL – Select one of sixteen Presets using GPI1 and GPI2.
This mode uses 8-state on GPI1 and binary on GPI2. In this mode, the
Scene Presets are always recalled from two consecutive banks – e.g.
Bank 1 and Bank 2. Select the Preset Bank pairs (1+2, 3+4 etc.) using
the Scene Bank parameter.
Idle state
“Idle” denotes GPI control being presently not active – i.e. the unit can still be
controlled as normal, adjusting parameters and recalling presets via the
TC Icon. However, once a non-idle GPI state is chosen, the selected Scene preset is
recalled, and normal functionality is blocked (which is also the case when GPI is
engaged in general).
Scene Bank parameter
If you have set the previously-described Function parameter to any value other
than “O”, you can select the Bank (or Banks) that Presets should be chosen
from using the Scene Bank parameter. See the recall modes for a more
thorough explanation.
Status eld
• The status eld is intended for diagnostics during the setup of GPI control.
• “-“ – GPI 1 is not enabled, or the incoming voltage is outside of valid
windows. Check the device’s GPI calibration, the incoming voltage and
the general external GPI setup.
• “Idle” – GPI is not controlling. The incoming GPI voltage may be at
maximum or not connected while the current setting for the Scene Bank
parameter in the same section includes the “idle” option.
• “1 (N/A)” – No valid User preset is stored in that specic library location,
and therefore GPI is not controlling. The behavior of the device is
identical to Idle state.
• “1, 2, 3, 4, 5, 6, 7, or 8” – Incoming GPI voltage is within the valid
window, and GPI is controlling Scene Recall. The TC Icon UI is locked.
Details regarding GPI signals: GPI 1 is receiving xed-state, latching
signals. A validation process is performed when receiving a new GPI
voltage. The incoming voltage needs to be within the specic valid
window for 500 ms before the preset change is initiated. The time
required for performing a change depends on the scope of that change
– e.g., wether it only involves parameters changes or the routing and
algorithm change as well.
