Introduction

K&F IPX Series amplifiers provide exceptionally high power density and powerful integrated DSP features, making them suitable for a broad range of installed and touring sound applications. All K&F IPX Series amplifiers feature both analog and AES3 inputs with link outputs; input mixing; comprehensive DSP functions (crossover, parametric EQ, delay and limiter control); network control via Ethernet on shielded Cat-5 cable or using suitable WiFi access point; IPX Controller software and iPad native app; comprehensive front-panel display and dedicated mute buttons; and both binding post and Neutrik speakON output connectors.

The information contained in this Quick Start Guide is sufficient for proper installation of K&F IPX Series amplifiers, and for configuration of settings in typical applications. Please refer to the full Operation Manual for detailed information on maintenance, cooling requirements, warranty, and configuration for complex installations.

Except as specifically noted, all features, values and connections are identical for the K&F IPX 1200 and K&F IPX 2400.

Unpacking and visual checks
Every K&F amplifier is carefully tested and inspected before leaving the factory
and should arrive in perfect condition. If any damage is discovered, please notify the shipping carrier immediately.

Save the packing materials for the carrier’s inspection and for any future shipping.

Installation

K &F IPX 1200 – Depth is 336 mm (13.2″) rack ear to back panel. Weight is approximately 5.3 kg (11.7 lbs). Rear support brackets are included and use is recommended in all applications.

K &F IPX 2400 – Depth is 423 mm (16.7″) rack ear to back panel. Weight is approximately 7 kg (15.4 lbs). Rear support brackets are included and use is recommended in all applications.

Cooling
Please ensure that there is sufficient space in the front and the rear of each amplifier to allow for a free flow of air. No doors or covers should be mounted either in the front or rear of the amplifiers. Amplifiers may be stacked directly on top of each other with no spacing, though some spacing may enable more convenient installation of rear cabling.
Operating voltage
All K&F IPX Series amplifiers have a universal power supply that operates on mains from 100 – 240 V at 50 or 60 Hz. The IEC receptacle on the rear panel accepts the supplied IEC cord which terminates in a connector appropriate for the country of sale. When AC power is connected, the amplifier goes into standby (red indication on standby LED). The amplifier may be turned on by pressing the front power button or remotely using the IPX Controller software.
Grounding
Signal ground is floating via a resistor to chassis, and therefore grounding is automatic. For safety reasons, never disconnect the earth (ground) pin on the AC power cord. Use balanced input connections to avoid hum and interference

Front Panel

The following indicators and controls are available on the front panel:

1. MENU – Selects MENU mode and confirms a given preset name.

2. BACK – Moves backward through menu layers in MENU mode.

3. MUTE – Mutes corresponding channel as indicated.

4. SIG – Illuminates green when signal is present. Illuminates red when signal is clipping (pre input mixer)

5. POWER – Indicates STANDBY (red)

6. LIM (limit) – Illuminates when the amplifier limits the signal. Limiting is engaged when the channel:

   • Reaches the selected voltage limit
   • Mains voltage cannot maintain full rail voltage

7. ADJUST/SET (Rotary Encoder) – Rotation moves through the menu and adjusts the currently selected parameter when in setup mode. Pressing down on the knob selects a given parameter or advances further into the menu.
   In operating mode, rotation of the ADJUST/SET encoder adjusts output gain (outputs ganged).

8. BACKLIT DISPLAY
   In operating mode, the display shows the following values and status indicators:

   • Level – Horizontal VU meters for each channel
   • Device name and Preset name
     In setup mode, the display shows currently selected menu locations and parameters. For more information on DSP setup procedures, please refer to the Operation Manual.
     Rear Panel
     
     The following connectors are available on the rear panel:

9. ANALOG INPUTS and LINK – female XLR input connectors provided for each channel, with nale XLR link output connectors.

10. AES3 INPUT and LINK – AES3 digital inputs are on an female XLR connector with a link output on an male XLR connector.

11. NETWORK (Ethernet) – An RJ45 jack is supplied for connection to an Ethernet network for external control and monitoring, either by a direct wired connection or via an external WiFi router to an iPad or tablet. LEDs below the connector indicate valid network connection (LINK) and network activity (ACT).

12.   speak ON OUTPUT CONNECTORS – Both channel outputs are available on a four-pole connector at the left; either channel 1 or both channels 1 and 2 may be connected. Only channel 2 is available on the connector to the right.

13. BINDING POST CONNECTORS – Connectors for channel 1 and channel 2.

14. AC LINE INPUT – A locking IEC receptacle accepts the AC line input, 50 Hz or 60 Hz, 100 V – 240 V. Use an IEC cable with the proper connector for country of use.

Input connections

Analog Inputs
Analog inputs are available on two standard female XLR latching connectors.
The inputs are electronically balanced. The impedance is 20 kΩ, and the inputs can accept a maximum input level of +26 dBu.
Polarity is as follows:
Pin 1 = screen (shield), pin 2 = positive (+), pin 3 = negative (-).

Balanced use with XLR connectors

input

1. = ground/shield
2. = hot (+ve)
3. = cold (-ve)

output
For unbalanced use, pin 1 and pin 3 have to be bridged

Analog Links
Two latching male XLR connectors are adjacent to the analog input connectors and are paralleled to the input connectors to provide an unprocessed analog loop-through to feed additional K&F IPX Series units or other equipment.
AES3 Inputs
A latching female XLR connector accepts an AES3 digital audio signal. Input impedance is 110 Ω. (Ensure that 110 Ω digital audio cables are used; standard XLR microphone cables are rarely suitable for reliable digital audio transmission.) AES3 is a stereo digital format, and therefore both inputs are fed via a single connector. Selection of the analog or digital inputs is made via the front panel display or IPX Controller software.
AES3 Link
A latching male XLR connector is fitted adjacent to the AES3 input connector.
This is an active link which sends an unprocessed AES3 loop-thru to feed additional K&F IPX units. The design requires no termination load when the unit is the last connected.

Output connections

Two types of power output connections are available on K&F IPX Series amplifiers: Neutrik speakON and binding post. The two types are connected in parallel. Loudspeakers may be connected to both at the same time, but this is generally not recommended as total impedance may be too low.
Binding Posts
Power outputs for loudspeaker connection are available on two fully enclosed binding posts. Observe signal polarity as indicated.
speak ON Connectors
Outputs for both channel 1 and channel 2 are available on a four-pole speakON connector to the left. The two-pole speakON to the right connect to output 2 only (see Fig. 1 below). See the amplifier’s back panel for information about the available pin outs for speakON connection.

Channel 1 and 2

CAUTION! Whe n connecting wiring to Speaker Terminals, the installation shall be made by an instructed person or ready-made leads or cords shall be used.
Bridge Mode
The K&F IPX Series employs an inherently bridged Class D output topology.
CAUTION! Under no circumstances should the K &F IPX Amplifier be bridged, this may cause undesired operating performance.

DSP configuration

Default configuration
K&F IPX Series amplifiers are shipped with default DSP settings that allow
immediate use in many common applications with no need for further DSP
configuration. The default mode is suited for use with the stereo program into
full range loudspeakers.
The default signal routing and parameter settings are as follows:

• Analog 1 and AES1: Routed to Ch. 1

• Analog 2 and AES 2 : Routed to Ch. 2

• AES3 to analog failover: OFF

• Mode: Stereo

• Input levels: 0 dB

• Input EQ: Flat
