    8. INSTALLATIoN The KA14 is the height of two rack units (2U) and can be mounted in an EIA-standard 19’’ rack using two rack adapters (included). In case of installation on a flat surface, use the four rubber pads included.

  • Page 9: Voltage And Current Requirements

    5 VAC. 9.1 voLTAGE REQUIREMENT The KA14 accommodates AC mains power operating at either 115 V or 230 V. The amplifier will continue to operate safely, without interruption, provided the AC voltage remains within a nominal range of 100 - 240 V (operating range 85 - 264 V) at 50 to 60 Hz.

    KA14 Ver. 1.2 10. BACK PANEL AC INPUT. Power socket IEC 320 C14. POWER ON LED. Indicates the amplifier is ON. XLR MIC/LINE INPUTS. Female balanced XLR analog inputs, with selectable sensitivity for Mic (-30 dBu) or Line (+4 dBu). These two inputs accept balanced, low impedance audio signals which allow the use of long cable runs (>10mt), without losing the quality of the signal.

  • Page 11: Signal Flow

    RCA OUT L KA14 Signal-flow The KA14 features two independent input processing channels (CH1 and CH2) and four independent output processing channels (A1, A2, B1, B2). The physical inputs (XLR 1, XLR 2, RCA L and RCA R) can be assigned to any input processing channel thanks to the Input Matrix .
  • Page 12 KA14 Ver. 1.2 The processing input channels CH1 and CH2 can be independently equalized via the K-framework software, then they can be routed to any output channel (A1, A2, B1, B2) thanks to the Output Matrix . The user can adjust the level of the four output channels independently. If necessary, the phase can be inverted on each output channel.

    KA14 Ver. 1.2 12. ToUCh SCREEN fUNCTIoNS The main functions of the onboard DSP can be managed with the integrated touch screen. Functions are grouped into six pages, shown as icons on the Home page. hoME PAGE To reach the homepage from any other page, touch the Home button.
  • Page 14 KA14 Ver. 1.2 DELAY The Delay page allows users to independently set the delays for the B1 and B2 output channels (up to 6 m). The delays are available on these outputs because they are often used to realign the subwoofers (connected to the B1 and B2 outputs) with the mid-high speakers (connected to the A1 and A2 outputs).

    KA14 Ver. 1.2 PRESET The Preset page allows users to load presets stored on-board. INfo The Info page contains information about the current software and firmware, and the Board ID of the amplifier. When connecting the amplifier in a K-framework network, please make sure that all devices in the network have different ID numbers.
