RCS Audio-Systems PMX-614 Power Mixer, 14 channels, 2 x 300 W content_copy

The PMX-614 from RCS Audio-Systems is a 14-channel power mixer designed for professional use in live events, sound reinforcement, association applications, and church facilities. The device combines a mixing console, effects processor, and integrated power amplifier in a compact housing, creating an all-in-one solution with high sound quality and operational reliability. The combination of mixing functions and amplifier power enables direct connection to speakers without additional amplifiers, simplifying installation and reducing space requirements.

Applications

The PMX-614 is suitable for applications requiring a compact, powerful sound reinforcement solution. These include events in churches, association rooms, small stages, or outdoor events. The integrated amplifier with 2x 300 W at 4 Ohm provides sufficient power for medium to large rooms. The ability to use the amplifier independently of the mixer expands the application range, for example, in pure playback scenarios or in combination with external mixers.

Functions and Equipment in Detail

The input interface includes six mono channels, which can be operated via XLR connectors for microphones or via 6.3 mm jack connectors for line signals. Channels 7/8 and 9/10 can be operated either mono or stereo, while channels 11/12 and 13/14 can be used as stereo aux returns or line inputs. Each channel features individual tone control, with channels 1 to 3 equipped with semi-parametric midrange control (100 Hz to 8 kHz) and a low-cut filter (18 dB/octave at 75 Hz). Channels 4 to 10 are equipped with a 3-band channel EQ, consisting of highs (12 kHz shelving ±15 dB), mids (2.5 kHz peaking ±12 dB), and lows (80 Hz shelving ±15 dB). Additionally, each channel has two pre-fader and one post-fader AUX paths, enabling flexible monitor and effects routing. Phantom power for all microphone inputs is centrally switchable.

Technology Explained Simply

The integrated amplifier delivers an output power of 2x 300 W at 4 Ohm and 2x 200 W at 8 Ohm. The outputs are available via Speakon connectors or parallel jack connectors, enabling flexible cabling. The amplifier section can be switched between two operating modes: Monitor L+R or Stereo L/R. A graphic master EQ and a subwoofer output with a switchable low-pass filter (LPF) are also integrated. The device features an optional 24-bit DSP effects module with 99 effects, which can be mixed into the main sum and monitor path via a DSP master fader. Operation is performed via a digital display with UP/DOWN buttons.

Compatibility and Accessories

The PMX-614 can be operated as a tabletop unit or installed in a 19˝ rack using the optional mounting bracket set RMK-14 P. The installation occupies 9 HE. The amplifiers can be used independently of the mixer by disabling the mixer section via the amp input. This allows the device to be used as a pure amplifier, for example, in combination with an external mixing console. The inputs and outputs are designed for standard cabling, with input sensitivity for microphone inputs at -55 dBm (1.38 mV) and for line inputs at -35 dBm (13.8 mV). The stereo input has a sensitivity of 0 dBu (775 mV). Output sensitivity is -10 dBu (245 mV) for Tape-Out (L/R) and +4 dBu (1.23 V) for all other outputs.

Mounting and Installation

The device is designed for tabletop use and can optionally be installed in a 19˝ rack, requiring the mounting bracket set RMK-14 P. Dimensions are 470 mm (width) × 405 mm (height) × 148 mm (depth). Installation is performed via the designated connectors and plug-in connections. Power supply is 220 V to 240 V/AC, 50–60 Hz. Power consumption is 900 W. The frequency response is 20 Hz to 20 kHz (+1 / -2 dB), covering the full audible range. Signal-to-noise ratio is better than 97 dB, crosstalk attenuation better than 90 dB, indicating high signal quality.

Advantages in Operation

The PMX-614 offers high operational reliability due to the integrated amplifier and flexible signal processing. The ability to use the amplifier independently of the mixer increases application flexibility. Central phantom power and multiple AUX paths facilitate integration into existing systems. DSP effects and the graphic master EQ enable precise sound shaping. Optional mounting in a 19˝ rack facilitates integration into professional installations.
