NOTE: Special local electrical safety compliance regulation may apply! KW-18 might be used from a single, two or even 3 phase power! In every case, all three Neutrik PowerCON Connector has to carry Phase, Neutral, and PE! A missing Neutral line might cause damage to the KW-18! To ensure the full output power capability, the amplifier needs to run with all 3 connectors connected and powered using 16A Type "C"... -

20kOhms. Usual drive capacity of DSP units on the market is 600 Ohms. Daisy chaining more inputs (and/or more KW-18 units) is limited therefore to 16 inputs altogether (625 Ohms) with the input signal attenuators at their minimum positions. With all attenuators at their maximum position, the number of inputs driven in parallel (daisy chained) could be as high as 32!Voltage gain of the KW-18 power amplifier is 30dB with the Input Signal Attenuator at its maximum position. -

Lambda Labs - Professional Acoustics KW-18 Amplifier Manual Attention: In the minimum position (fully counter-clockwise), a nearly infinite attenuation is provided. In this case, the input impedance of the corresponding channel is 10kOhms. ATTENTION! Attention: In the maximum position (fully clockwise), no attenuation is provided and the voltage gain of the corresponding channel is 30dB. -
Page 19: Dust Filter
Danger: Do not use the amplifier without a dust filter! DANGER! Attention: Using hazer and/or fog machine fluid can cause a very fast saturation/blockage of the amplifier dust filter foam! In such cases, Lambda Labs recommend checking/cleaning the dust filter on a daily basis! ATTENTION! Attention: Having reserve dust filter foam is also recommended. -

7. Rack Installation 7.1. Front Mount The KW-18 professional power amplifier can be mounted into a standard 19” rack case. The dimensions (mm) for the rack mounting is depicted on the drawings above. Danger: You should always use all 4 screws for the front mount in a 19” rack! Use standard 6mm rack... -
Page 21: Rear Mount
This kind of cooling relies on sufficient fresh air supply. To achieve this, KW-18 has air vents on its front panel, rear panel and on its sides. These air vents should never be covered! Caution: For sufficient cooling, the dust filters on the front panel air vents must be always kept clean and dry! For more information on cleaning the dust filters please refer to the Chapter 6.3 Dust Filter &... -
Page 22: Maintenance
Check the filter foam after every use! If needed clean it with water! Danger: Do not remove the top cover (or the rear section) and do not open the KW-18 power amplifier unit! No user serviceable parts inside! Servicing should be always performed by qualified personnel! -
Page 23: Cleaning
8.1. Cleaning Keep your KW-18 units clean and dry! Cleaning should be performed regularly using dry or slightly wet cloth! After removing the dust filters, you might use clean (oil and liquid free) high pressure air to remove dust from the inside. Never use air with a too high pressure for the cleaning! Lambda Labs recommends air pressure of 2-4 Bar. - Page 24 Lambda Labs - Professional Acoustics KW-18 Amplifier Manual www.lambda-labs.com ! 2 3...
