The section you are in will always be bold with the other sections "grayed out." The feature allows you to jump directly to another section without having to return to a Table Of Contents page.

This power amplifier can produce dangerous output voltage, power and sound pressure levels. In order to minimize the risk of injury, damage, or hearing loss, please read the entire owner's manual.

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying the device.

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

The KLR Series

KLR-Series amplifiers are high-efficiency, lightweight high power amplifiers incorporating the latest amplifier technologies.

The series provides a power range of 1000 to 2500 watts per channel at 2 ohms (20Hz-20kHz, 1% THD). The KLR series is available in 2 channel versions at four power points. All models will drive 2, 4, or 8 ohm loads.

*The KLR 3200 can also be used as a two channel 70V distributed output amplifier providing up to 800W per channel. For 70V applications, Ashly recommends setting the amplifier's HiPass filter switch to 50Hz (see page 5).

KLR-Series Power Ratings (per channel)
	Stereo				Mono
Model	70V	8Ω	4Ω	2Ω	4Ω
KLR 2000 X 350W	600W	1000W	2000W
KLR 3200*	800W	650W	1100W	1600W	3200W
KLR 4000 X 850W	1400W	2000W	4000W
KLR 5000	X	1000W	1700W	2500W	5000W

• Inputs are via 3-pin Euroblock, XLR, and 14 " TRS connectors.
• Switch mode power supply provides high efficiency and low weight
  • Output connectors are four pin Speakon type.
• Rear panel switches include: Gain and Operation Mode, Limiter, and HPF.
• Forced air cooled (front panel intake, rear panel exhaust)
• Front panel indicators for output level, clip/protect, and power on/off
• Gain selectable switch for both channels
• Removable dust filters on front panel
• Rack ears for permanent installation in a standard 2RU 19"(rack mount width) enclosure

Protection

KLR-Series Amplifiers come standard with several protection circuits:

√ Output over-current protection
√ DC output protection
√ Chassis internal temperature monitoring
√ Inrush limiting
√ Mains circuit breaker (Mains fuse used in KLR-5000)

WARNING: Do not remove the mains connector ground.

Installation

KLR-Series amplifiers are designed for use in both fixed and mobile sound systems. Each amplifier is shipped (unless otherwise specified) with the following factory settings:

Front panel: Rear panel:
On/Off Switch = OffAttenuators =∞	High Pass Filter(s) = OffGain Selector = Max Gain PositionMode Selector = StereoLimiter Switch = Off

Before connecting to mains power, make sure that the switches are set to the configuration needed for your particular application. Always switch the amplifier off before making any changes to the settings. Failure to do so could result in damage to the unit or other components in your system. CAUTION: When mounting or connecting the amplifier, always disconnect it from the mains. Use four screws and washers when mounting the amplifier to the front rack rails. Rear support is also recommended, especially for mobile or touring use. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

Requirements

KLR-Series amplifiers have specific physical, electrical and signal requirements for proper operation. These requirements will vary depending on your specific application, setup, and the settings on the amplifier. When setting up and testing your system, please take special care to double check all connections and settings. Please refer to the specifications section of this manual for specific input, output and other figures.

Installation Density

KLR-Series amplifiers produce substantial power output from a small chassis. When driven at the higher-end of their potential, they do produce heat that must be dissipated. In cases where multiple KLR amplifiers are mounted together (or a single KLR with other equipment), it is recommended that a 1RU space is left between units to allow for proper air circulation. If the amplifier overheats, it will go into ‘thermal’ protect mode to prevent damage to itself and any connected components and speakers.

Connectors & Polarity

KLR-Series amplifiers utilize three types of professional audio connectors. For the inputs, 3-pin Euroblock connectors are utilized with their polarity clearly marked on the amplifier's rear panel, and combination XLR and 1/4" phone jack are all wired in parallel. Outputs are four pin Speakon type connectors. The polarity for these connections is marked on the unit's chassis. Note that polarity changes when the unit is operated in BRIDGED mode. Be sure to read the Operation section of this manual for important information on the operating modes.

Hiss Hiss Unplug the amplifier input to confirm that the		hiss is coming from the source or from a device upstream. Erratic or popping noises indicate an electronic fault in the offending unit. To keep the noise floor low, operate the primary signal source at full level, without clipping. Avoid boosting the signal further between the source and the amplifier.
Squeals and Feedback	Squeals and Feedback Microphone feedback should be eliminated with mixer controls. If noise continues to build up with no microphone gain, there is a serious fault in the signal processors or cables.Working in succession from the signal source towards the amplifier and check each device in the signal path by reducing its gain or by unplugging it.
