RCS Audio-Systems PMX-1216 Power Mixer, 16 channels, 2 x 600 W content_copy

The PMX-1216 from RCS Audio-Systems is a professional power mixer with 16 channels and a total power output of 1200 watts, designed for use in event technology, such as live events, conferences, or in studios. The device combines a full-featured mixer section with integrated power amplifiers, enabling it to be used both as a mixer and as an amplifier. The output power is 600 watts per channel at 4 ohms, while at 8 ohms, a power output of 350 to 520 watts per channel is achieved. The power supply operates on 220 V to 240 V/AC at 50 to 60 Hz, with a power consumption of approximately 2200 watts.

Applications

The PMX-1216 is designed for professional applications requiring a compact, high-performance solution for audio transmission. It is suitable for mobile events, small to medium stage setups, schools, churches, or as a main amplifier in small studios. The integrated power amplifier allows direct drive of speakers without additional amplifiers, simplifying the system architecture. The option to switch off the mixer section and use the amplifiers via the Amp-Input increases flexibility in operation.

Functions and Equipment in Detail

The input section includes 8 mono channels, which can be connected via XLR connectors for microphones or 6.3 mm jack connectors for line inputs. Channels 9/10 and 11/12 can be operated either mono (L) or stereo (L/R), while channels 13/14 and 15/16 are used as stereo aux returns or line-level channels. Channels 1 to 8 feature individual preamplifier controls (Gain for microphones, Trim for line inputs), while channels 9/10 and 11/12 have input level switches. Channels 1 to 4 are equipped with low-cut switches and a 3-band channel EQ, with the midrange control for channels 1 to 3 being semiparametric (100 Hz to 8 kHz). Channels 5 to 10 also feature a 3-band channel EQ. Pan controls are available for mono channels, while balance controls are provided for stereo channels (except 13–16). A variable headphone output allows monitoring of all channels, as well as monitoring of the monitor sum, Main L/R, Mono-Out, and AFL/PFL. Each channel has two pre-fader and one post-fader aux sends, with channels 5 to 8 featuring an integrated CH-Insert. Phantom power for all microphone channels is centrally switchable and provides +48 V DC.

Technology Explained Simply

The integrated power amplifier delivers an output power of 600 watts per channel at 4 ohms, ensuring high volume and clear reproduction. The output sensitivity is +4 dBu (1.23 V) for Main-Out, Mono-Out, Aux-Send 1/2, and Monitor-Out, which is typical for professional applications. The Tape-Out (L/R) has a sensitivity of -10 dBu (245 mV), suitable for connections to recording devices. The frequency response ranges from 20 Hz to 20 kHz with a tolerance of +1 / -2 dB, enabling full reproduction of the audible range. The signal-to-noise ratio is better than 97 dB, indicating high sound quality and low background noise. The crosstalk rejection is better than -90 dB, ensuring clear separation between channels. Channel tone control includes highs (12 kHz shelving ±15 dB), mids (2.5 kHz peaking ±12 dB, semiparametric 100 Hz–8 kHz ±12 dB for CH 1–3), and lows (80 Hz shelving ±15 dB), as well as a low-cut filter with 18 dB/octave at 75 Hz.

Compatibility and Accessories

The PMX-1216 can be operated as a tabletop unit or installed in a 19˝ rack using optional mounting brackets RMK-16 P. The amplifier outputs are available via Speakon connectors or parallel jack connectors. The master section includes a stereo master fader (L+R), an LED meter display, and a graphic EQ L/R. The Amp-Mode allows selection between L+R Monitor or L/R Stereo. RCA inputs and outputs with level controls and solo switches are provided for 2-Track IN/OUT (L/R). A mono fader with a switchable LPF is used for Sub-Woofer-Out, Main L/R, and Monitor Pre-Amp-Out for external amplifiers.

Effect Section

A switchable 24-bit digital effects board with 99 high-quality effects can be mixed into the main sum and monitor path via a DSP master fader. Operation is via a digital display with UP/DOWN buttons, enabling intuitive control.

Mounting and Installation

The device is designed as a tabletop unit but can be integrated into a 19˝ rack using optional mounting brackets RMK-16 P. Dimensions are 515 mm (W) × 405 mm (H) × 148 mm (D). Installation is carried out via the provided connectors and faders, with power supplied via the mains. The integrated power amplifier allows direct drive of speakers.

Advantages in Operation

The PMX-1216 combines a mixer and power amplifier in one unit, reducing system complexity and speeding up installation. The high output power and excellent signal-to-noise ratio ensure clear, loud reproduction. Flexible channel assignment, integrated effects, and the ability to switch off the mixer section expand usage options. Operation is intuitively designed via front panel controls and the digital display for effects. The use of Speakon and jack connectors offers flexibility in cabling. Phantom power is centrally switchable, simplifying operation. Dimensions and weight (16 kg) are designed for professional use, with the option of rack mounting facilitating integration into existing systems.
