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 = Off
Attenuators = œ| High Pass Filter(s) = Off
Gain Selector = Max Gain Position
Mode Selector = Stereo
Limiter 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.
Typical Applications
(Note: KLR 5000 not shown – see page 5) 
The most common use of a KLR-Series amplifier is a
2-channel source driving 2 speaker channels. In this illustration, the
amplifier is receiving a stereo signal and is driving two stereo speakers. The
amplifier is in STEREO mode.
Another use of a KLR-Series
amplifier is a single channel source driving both speaker channels. In this
illustration, the amplifier is receiving a signal and is driving both channel
speakers with the same signal. The amplifier is in PARALLEL mode.
KLR-Series amplifiers are well suited to BRIDGED operation to drive a speaker
load such as a subwoofer. This illustration shows a KLR driving a signal in
BRIDGED mode. Note the special wiring to the channel 1 connector for Bridge
mode. Minimum Bridged load impedance is 4Ω (2Ω per channel).
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. 
Speaker Connections (Note: KLR 5000
speaker outputs not shown – see page 5) Stereo Speaker Wiring
In this mode, the amplifier’s channels operate fully independent of each other. Each signal enters the unit and is amplified separately and wired using different connectors.
Stereo Speaker Wiring Using Single
4-Conductor Speaker Cable
In this mode, the amplifier’s channels still operate independent of each other. Each signal is amplified separately, however both channels are wired using the Channel 1 connector.
Bridged (Mono) Mode
In this mode, a single input is connected to channel 1 and is connected to the two output channels that have been “Bridged” together using the Channel 1 connector. Minimum Bridged load impedance is 4Ω.
Troubleshooting

|---|---|---|
| No Sound | Signal LED not lit Clip LEDs not lit | Check AC plug. Confirm that AC |
outlet works by plugging in another device.
Signal LED not lit| Make sure the signal source is operating and try another
cable. Check position of Volume Pots.
Signal LEDs responding to signal level| Check the speaker wiring for breaks.
Try another speaker and cable.
Protect LED is lit| Overheating will cause protective muting. Check for proper
ventilation.
No Channel Separation| No Channel Separation| Check the mode indicators on the
back panel and make sure the mode selector on the rear panel is in the stereo
position. Make sure other equipment in the signal path such as mixers and
preamps are set for stereo, not mono
Distorted Sound| Power LED is lit| A faulty speaker or a loose connection
could cause this. Check the wiring and try another speaker.
Signal LEDs responding to signal level| The signal source might be clipping.
Keep the volume pots at least halfway up so that the source does not have to
be overdriven.
Clip LEDs not lit| Keep the volume pots at least halfway up and try changing
input sensitivity with the gain selector on the rear.
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.
