Ascentic Demonstration AudioHub AH1
Model AH1 Demonstration AudioHub
The AH1 plays MP3, FLAC, OGG, and WAV files for high fidelity audio
demonstrations of headphones, speaker docks, and sound bars. It is ideal for
use with one or more Audio Authority® audio distribution amplifiers. Two audio
outputs may be played and adjusted individually or together (Toslink® digital
and analog outputs). Push buttons, sensors, and/or a multifunction rotary knob
allow track selection and volume adjustment. The special Visual Volume™ knob
(Model 1895, purchased seperately) provides visual feedback with its glow
ring.
- Push buttons may be used to adjust volume and select tracks. They are available in several styles and colors; pictured above is a stainless steel button illuminated with blue LED ring.
- EasyPlug push-buttons are terminated with RJ9 connectors on either end of the cable for quick and secure installation.
- The Visual Volume™ Model 1895 Rotary Control gives visual feedback with its glow ring, its brightness indicating changes in volume; a slow pulse highlights the knob during attract mode.
Button and Rotary Control Functions
Default button positions are shown on page 2, and alternate functions may be applied with custom firmware. Control volume using a rotary control knob or up/down push-buttons. Volume levels are always synchronized for each Digital and Analog Output pair. To control volume on Output A and B individually, use two sets of push buttons. To control all outputs with one control, any method may be used including Model 1895 (see Linked Volume).
- Volume Up and Down A : Connect button to increase or decrease Output 1 volume.
- Volume Up and Down B: Connect button to increase or decrease Output 2 volume.
- Next Track: Play the next track on the card; if no demo is playing, the first track starts.
- Previous Track: Play the previous track on the card; if no demo is playing, the first track starts.
- Rotary Control (PN 1895): Connect a 1895 knob to the RS-485 port. Push to play next track, and turn to adjust volume on all outputs.
Play Modes
Choose the desired features and select using the Play Mode Switches as shown.
If a switch is shown with a dash, it can be ON or OFF while using the feature.
TIMEOUT : When Play Mode Switch 1 and/or 2 is on, the demo ends after a period of inactivity. The timeout interval is the time between the last button press or knob turn until the demo ends and attract mode begins. Adjust the length of the timeout interval using the settings below. When Switch 3 is ON the demo never stops playing, but volume is reset to the default level for attract mode.
TIMEOUT SWITCH SETTINGS:

CONTINUOUS PLAY:
When Switch 3 Continuous Play is on, the AudioHub plays and repeats all tracks
on the microSD card, nonstop, at the volume last set. Default Volume and
Timeout can be used with this mode, however when the demo times out the
playback continues, but at the volume level selected on the Default Volume DIP
switches.
CONTINUOUS PLAY SWITCH SETTINGS:
| 1 | 2 | 3 | 4 | 5 | 6 | |
|---|---|---|---|---|---|---|

VOLUME RESET: When Continuous Play and Timeout are on, the AudioHub returns to the chosen volume after a timeout, then continues to play at the default volume. See Default Volume below.
DEFAULT VOLUME: Switch 4 and 5 selects the level of Default Volume at initial power up and between demonstrations when Timeout is active.
