Installation Guide AXB-VOL3 3-Channel Volume Controller Overview Installation The AXB-VOL3 (FG5756) controls three audio volume channels. Each line-level channel, opto-isolated from system ground, can be configured for balanced or unbalanced line operation. It is programmable for 128 steps of audio level, audio mute, variable ramp speed and level presets. Setting the DEVICE DIP Switch Note: Use the DIPSwitch 2.0 application available for free download from AMX to quickly figure out DIP Switch settings for all types of DIP Switches. Set the device number on DEVICE DIP switch, located on the front of the AXB-VOL3. The device can be 1 of the 255 devices in an Axcess control system. The device number must match the device assignment in the Axcess program. Device numbers are assigned into the following three segments: • Cards 1 through 95 • Boxes 96 through 127 • Panels 128 through 255 Set the device number by setting the device DIP switches. The device number is the total of all of the switches in the ON position, and take effect by cycling the power.

Line operation: Balanced or unbalanced Audio ground: Audio ground opto-isolated from system ground. -10 to +4 dBm. Max. input/output level: +16 dBm. Volume level resolution: 128 volume level steps (+ .5 dB per step). Attenuation: 72 dB at full attenuation (mute). Total Harmonic Distortion: THD = <.008% Frequency Response 20 Hz to 20 kHz +/- 1 dB Front Panel Components AxLink LED (green and blinks to indicate AxLink communication activity and power: • Full-Off indicates no power is being received or the controller is not functioning properly. • One blink per second indicates power is active and AxLink communication is functioning. • Full-On indicates there is no AxLink control or activity, but power is On. Device DIP Switch An 8-position DIP switch used to set the AxLink device number for the AXB-VOL3. Channel LEDs Red channel LEDs 1 - 3. The LEDs individually light indicating a change in channel levels. Rear Panel Components AxLink connector 3. Wiring Guidelines Nominal input level: AxLink LED Strip 0.25 inch of wire insulation off all wires. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section. Tighten the screws to secure the wires. Do not tighten the screws excessively; doing so may strip the threads and damage the connector. 4-pin, captive wire connector, receives power and information via the AxLink and AxLink Central Controller. Volume Channel connectors 6-pin, captive wire connectors that control audio level, audio mute, variable ramp speed and level presets of up to 3 devices. Enclosure Metal with black matte finish Dimensions (HWD) 1.51" x 5.55" x 5.45" (3.84 cm x 14.10 cm x 13.84 cm) Weight 1.1 lb (0.499 kg) AxLink Power 12 VDC @ 230 mA The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8 power supply. The Central Controller supplies power via the AxLink cable or external 12 VDC power supply. The maximum wiring distance between the Central Controller and interface is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The table below lists wire sizes and maximum lengths allowable between the VOL3 and Central Controller. The maximum wiring lengths for using AxLink power are based on a minimum of 13.5 volts available at the Central Controller’s power supply.

The following sections list Axcess programming commands used with the AXB-VOL3. Command Description Channel Settings Commands Use the AXB-VOL3 channel settings listed for ramp up, ramp down and mute operations. AXB-VOL3 Channel Setting Commands PP Syntax: SEND_COMMAND VOL, ’P= P ’ Variable: Channel = Enter channel number. Examples: Channel Description Channel Description 1 Ramps channels 1 and 2 up. 7 Ramps channel 2 up. SEND_COMMAND VOL, ’P1 = P2’ 2 Ramps channels 1 and 2 down. 8 Ramps channel 2 down. SEND_COMMAND VOL, ’P1 = P3’ 3 Mutes channels 1 and 2. 9 Mutes channel 2. SEND_COMMAND VOL, ’P2 = P1’ 4 Ramps channel 1 up. 10 Ramps channel 3 up. Sets channel 2 level to the same as channel 1. 5 Ramps channel 1 down. 11 Ramps channel 3 down. Sets channel 2 level to the same as channel 3. 6 Mutes channel 1. 12 Mutes channel 3. Note: Ramping a volume channel while the mute channel is on will NOT automatically turn off the mute channel (will not restore) but the ramping will still occur and the volume change will be noticed when the mute channel is turned off. For setting ramp rates and presets, see SEND_COMMAND programming instructions below. For reading current volume levels and displaying bargraphs see CREATE_LEVEL and SEND_LEVEL programming instructions. Volume channels 1 through 3 use levels 1 to 3 respectively. When controlling levels, such as with an active bargraph, there is no LED indication of volume changes. Sets channel 1 level to the same as channel 2. Sets channel 1 level to the same as channel 3. SEND_COMMAND VOL, ’P2 = P3’ SEND_COMMAND VOL, ’P3 = P1’ Sets channel 3 level to the same as channel 1. SEND_COMMAND VOL, ’P3 = P2’ Sets channel 3 level to the same as channel 2. Note: You cannot use 'P0' with these commands. Levels • • • 1 = Output #1 2 = Output #2 3 = Output #3 SEND_COMMANDs System SEND_COMMANDs are stored in the Axcess Control System. AXB-VOL3 SEND_COMMANDs Command Description PLT Ramps specified channel(s) from current level to a specified preset level or percentage at the current rate or optionally in a specified amount of time. Syntax: SEND_COMMAND VOL, ’P
