API (Automated Processes Inc.) has established a new line of analog signal processing products under the name Arsenal Audio, which launched at Summer NAMM in Nashville. Arsenal Audio products feature robust design standards, and each unit is hand assembled. Three new products are initially offered: the R20 2-channel mic pre; the R24 2-channel, 4-band EQ; and the V14 4-band VPR 500 format equalizer.
Arsenal Audio R20 dual-channel mic preamp
The Arsenal R20 dual-channel microphone preamplifier features low-noise, high-quality inputs for both mic and instrument in a rackmount chassis with internal power supply. Each channel includes rotary gain control plus individual toggle switches for phantom power, phase, pad and mic/instrument input selection. The dual mic preamps each offer up to 55 dB of gain, while each front panel, high-impedance instrument input provides a maximum of 31 dB of gain. Each channel’s pad switch attenuates the mic input by -20dB, or the instrument input by -10dB. A pair of traditional analog VU meters with separate peak indicators is used for output metering. Both XLR and 1/4-inch outputs are fully balanced.
The Arsenal R24 features two identical channels of equalization modeled after the classic APSI model 562. The R24 is rackmounted with internal power supply. Individual continuously variable control knobs allow for separate adjustment of frequency and gain. All four bands are peak/dipping parametric design with 12 dB of boost/cut per band. EQ in/out is controlled by classic toggle switches. The Arsenal R24 includes a custom transformer-balanced output with extended headroom of +23 dB.
The Arsenal V14 i4-band equalizer is modeled after the classic APSI model 562 EQ, and is designed for the API VPR 500 Series rack format. Controls include dual concentric pots providing continuously variable adjustment of frequency and gain, plus an EQ in/out switch. All four bands offer peak/dipping parametric configuration with 12 dB of boost/cut per band. The Arsenal V14 includes a custom transformer-balanced output with extended headroom of +24dB.
