Citronic P Series 2.1 Power Amplifiers Key Features

  • Perfect for medium to large PA applications

  • Dedicated subwoofer output with Lowcut & Filter 

  • Gain control for each channel and sub

  • 19" Rack-mountable (ears supplied)

Powerful Output

The Citronic P44800 has a high power output of 2 x 250W + 500W (sub) @ 8 Ohms, and 2 x 400W + 800W (sub) @ 4 Ohms. All of the outputs are on Speakon (SPK) connections.

The Citronic P551000 has a high power output of 2 x 350W + 700W (sub) @ 8 Ohms, and 2 x 550W + 1000W (sub) @ 4 Ohms. All of the outputs are on Speakon (SPK) connections.


Filter Facility and Low Cut

A Low Cut switch is provided removing the very lowest frequencies which may be inefficient for speaker drivers to reproduce, wasting power on inaudible output.

The SUB output has a filter facility, which can be switched on via the FILTER switch. When this is switched on, the SUB input is inactive and the SUB amplifier is fed from the CH1 and CH2 inputs (merged together) and the filter removes all of the signals above a cutoff frequency, allowing only low frequencies to be amplified. The cutoff frequency may be adjusted between 50Hz and 250Hz via the FREQ rotary control. A recommended start point is mid-way (approximately 150Hz) - this can be adjusted later as required.

The P-Series amplifiers have dedicated gain control for each channel and the sub.

These professional amps have a “soft-start” function which makes some checks before engaging power to the amplifiers, which may take a few seconds.


Multiple Inputs

The P44800 and P551000 power amplifiers offer both 6.35mm Jack and female XLR inputs, so you can connect a range of devices such as mixing desks, microphones and line splitters etc.


The Citronic P Series amps can be installed into a 19" rack cabinet or case. Rack-ears are supplied in the box. The carry handles can also be removed if necessary.
