Product Information

Thank you for choosing KGEAR!

• To ensure proper operation, please carefully read this owner’s manual and safety instructions before using the product. After reading this manual, be sure to keep it for future reference. If you have any questions about your new device, please contact K-array customer service at info@kgear.it or contact the local distributor in your country.
  GF82 I, GF82T I, GF82A I are the medium-size and
• minimalist line array elements of the GF family in a practical and compact column format, and a resistant frame. The GF82 I, GF82T I, and  GF82A I comprise 8×2” ferrite magnet woofers closely-spaced into a recycled ABS enclosure, featuring PAT (Pure Array Technology).
• These column speakers are the perfect solution for speech reproduction with high definition and intelligibility, thanks to their directivity and a narrow vertical dispersion, as well as music reproduction when coupled with a KGEAR subwoofer.
  GF82 I is a 200W line array element with selectable
  impedance: low Z – 16 Ω / high Z- 64 Ω.
• GF82T I has the feature of an internal transformer, and it is compatible with high voltage lines at 70V or 100V and has different power taps: 4/8/16/32 W @ 100V or 2/4/8/16 W @ 70V.
• GF82A I is an active speaker with a built-in amplifier module with a balanced line input, a mute contact and an auto ON-OFF switch with selectable thresholds, plus a speaker output to connect another KGEAR speaker or passive subwoofer from the KGEAR GS family.

GF82A IControls

GF82A I features 2 x Phoenix connectors (4-pin Euroblock 1,5/ 4-ST-3,81) with:

INPUTS:

•  1x balanced line input
•  1x mute contact (normally open) – more information about mute wiring and connections in the Mute contact section on the next page.
  OUTPUTS:
•  1x speaker output to connect another KGEAR speaker or passive subwoofer driven by the built-in amplifier module, 4 Ω minimum load.
  CONTROLS:
•  1x auto ON/OFF switch with selectable thresholds dip switch controls the auto-standby mode of the speaker and can be set to 3 different thresholds – see the table on the next page for more information about ON/OFF switch modes.

Mute Contact

It is possible to connect an external switch to the Mute contact input to close the circuit down and switch the speaker off. Please follow the wiring scheme below.

It is possible to use the G-AL120 power supply accessory to provide power to the internal amplifier module. This accessory can drive up to 1x GF82A I amplifier module and 4x GF82 I connected in parallel with the LOW-Z -> 16 Ω impedance selection. With a minimum load of 4 Ω, the amplifier module is capable of delivering a power of 100 W with a maximum consumption of 6.5 A (Irms).

DIP Switch modes

The table below illustrates the three different modes available along with their corresponding input signal values/threshold values, which can be used to configure the ON/OFF switch.

TRANSFORMER’S POWER TAPS

GF82TI Transformer wiring

GF82TI has the feature of an internal transformer and it is compatible with high voltage lines at 70V or 100V and has different power taps: 4/8/16/32 W @ 100V or 2/4/8/16 W @ 70 V.This selector makes it easy to connect a large number of speakers in parallel with high power and efficiency and setting different output levels on each speakers, for every kind of use and different settings. GF82T can be installed with a dedicated IP accessory G-IPCAP2.

CONNECTORS

 

G-IPCAP – IP sealing accessory

GF82, GF82A and GF82T can be protected against external agents, salt, chlorine and water using the G-IPCAP1 and G-IPCAP2. These are dedicated IP  sealing CAP made of highly resistant and tight rubber, thought to be mounted at the rear panel of the speakers to protect connectors from water. G-IPCAP1 is thought to be mounted to raise the IP grade of GF82 passive speaker and GF82A active speaker, while G-IPCAP2 is dedicated to the GF82T speaker witha transformer. To install the speakers with the dedicated accessory, please follow the procedure shown below:

1. Take the dedicated accessory G-IPCAP1 and make a hole in the rubber material with a bradawl.
2. Choose a cable with a sheath for greater insulation and pass it through the hole.
3.  Connect the wires to pins 1 – 4 of the provided Euroblock connector and plug it into the speaker terminals
4.  Use the jumper cables for the desired impedance configuration.
5. GF82A connections are shown in the picture below. For external input and DC power connection, connect the wires to the provided connector and plug it into the speaker terminals at the top of the rear panel.
6. Connect the wires for speaker output to the terminals at the bottom of the panel
7.  Ensure a secure fit by firmly pressing down the accessory’s gasket to close the connector compartment.
8. Connect the speaker to the dedicated amplifier channel. Finally, GF82 is installed with its dedicated G-IPCAP1 or G-IPCAP2 accessory

Example of configuration
It is possible to mount more GF82 elements in an array setting, connecting each speaker with a high impedance configuration. In this example, 16x GF82 are connected with the selected impedance and driven by a single channel of GA43L/GA46L amplifier..
