VPL DIP-switch is set to maximum at the specified nominal load, the amplifier channel is able to deliver maximum rated output power. (PWR) Power on (Blue). - It's normal for the LED to illuminate "BLUE" during power on. Zenith 10K4 Amplifier Manual...
6.2.3 Input and output connectors The amplifier of 10K4 is equipped with balanced XLR-F input connectors. SpeakON output connectors (SP). For specific configuration and wiring information, see section 7.4. - Audio inputs – four channel models Input connectors - SpeakON outputs –...
When need to pull out the module, stirring the plug in/out bar to the handle (right side), the module will draw out from the position automatically, and then pull out the module easily and simple. - Change modules one at a time. Do not repeatedly insert/remove the modules. Zenith 10K4 Amplifier Manual...
Protection, Faults and Warnings section for further details. 7.3.1 Signal flow block diagram The input stage of 10K4 amplifiers has a high sensitivity to provide ample system headroom. This in effect means that the input stage is almost impossible to clip.
The chart to the follow of the drawing below show - When bridging two channels, you must add +6dB to input sensitivity for a 10K4 with a 8Ω load and 150V the input sensitivity to achieve maximum output peak (max.) and 38V peak (min.) respectively for the...
A typical output source (e.g. a DSP crossover unit) can drive up to four amplifier channels before external line-drivers might be required to buffer the signal. SpeakON inputs – four channel models Zenith 10K4 Amplifier Manual...

Channel A+B, provides outputs for both Channel A and Channel B. This output is useful when wiring the amplifier for bridged mono operation. See section 7.4.6. The left SpeakON connector provides an output for Channel B only. Connect the + and -loudspeaker cables as shown in the illustrations below. Zenith 10K4 Amplifier Manual...
The unique adjustable input gain feature of the 10K4 amp li fie r makes it easier to attain the - Use a high quality stranded loudspeaker cable, and optimum balance between headroom and signal-to- keep cable runs as short as possible.
Voltage Peak Limiter (VPL) is a unique feature in amplifier will not be damaged by forcing the 10K4 amplifiers. It is used to select the maximum amplifier to deliver current levels to the outputs that power available on each output channel. VPL levels exceed the physical limits of the transistors.
7.5 Protection, faults and warnings 7.5.1 Introduction The 10K4 amplifier incorporates a sophisticated and comprehensive set of protection features. Faults and warnings are indicated on the front panel and reported. 7.5.2 Safe Operating Area Detector (SOAD) The Safe Operating Area Detector (SOAD) compares output voltage against output current to ensure that the output transistors are working inside their safe.
This can result in tripping of fast- acting amplifier has gone into maximum current protection. mains breakers. Such is not the case with 10K4 This situation is caused by an excessive input signal amplifiers. The 10K4 amplifiers have very low inrush and is not due to a short circuit.
The potentiometer's operational range is 0dB to minus infinity. Attenuation is logarithmic, with -10dB at the 12 o'clock position. 7.6.3 Mute indication Individual channel Mute is indicated by illumination of the red MUTE LED provided for each channel. Zenith 10K4 Amplifier Manual...
The amplifier requires servicing before placing back in operation. 7.7 2Ω load overheat protection In the situation the amplifier is used to power 2Ω loads, the internal monitoring system will reduce the output power automatically to prevent amplifier overheat. Zenith 10K4 Amplifier Manual...
The module incorporates a lever system together with a card edge style connection system secured by an automatic spring locking mechanism. The 10K4 amplifier modules rely on all four modules being installed for cooling and air management to be effective. Do not operate the amplifier for extended periods without all four modules installed.
