Electro-Voice PolarChoice Desktop 18 (PC Desktop-18) - Multi-pattern desktop microphone with stand, 18" gooseneck, and LED mute

The Electro-Voice PC Desktop-18 is a high-quality, dual-section gooseneck desktop microphone with a rugged steel base , designed for conferencing, education, worship, and corporate AV environments. It features four switchable polar patterns (omnidirectional, cardioid, supercardioid, and hypercardioid) that maintain a consistent on-axis voice , requiring no re-EQ when changing directivity. The large LED mute switch is programmable without opening the mic for push-on/off , push-to-mute , or push-to-talk operation , and includes an Automix (always-on audio) mode for integration with automatic mixers. RF Shield electronics provide high RFI/GSM immunity ; a switchable high-pass filter helps control vibration and rumble . Phantom power 12–52 V DC , balanced output 200 Ω and response 50 Hz–20 kHz , with OCV 5.6 mV/Pa , noise <26 dB(A) , dynamic range >109 dB and clipping >135 dB SPL . Supplied with multi-port windscreen and integrated 3.0 m cable terminated in male XLR .

Main features

• Multi-pattern with consistent voice : omni, cardioid, supercardioid and hypercardioid switchable from the base.
• Complete operational control : mute with programmable blue LED (latch or momentary), power-up state selection, and Automix mode for logic/LED control from the mixer.
• RF Shield : High immunity to RF/GSM interference in rooms with mobile phones.
• 18" ( 470 mm ) double-section gooseneck with rigid center section for stable and discreet positioning.
• Steel base with switchable high-pass filter , bottom access to all switches, and included multi-port windscreen .
• Professional Integration : 12–52 V phantom power, 200 Ω balanced output, 10 ft (3 m) fixed cable with male XLR .

Product benefits

• True versatility to adapt coverage to rectangular or oval tables or multi-speaker panels without changing microphones.
• Intuitive operation for the user (large button with LED) and quick configuration for the technician (selectors accessible without disassembly).
• Cleaner audio thanks to RF shielding and high-pass, with optimized gain-before-feedback through directional patterns.
• Easy installation on tables or lecterns with a heavy base and ready-to-connect XLR-terminated cable.

Use cases

• Conference rooms, board meetings and courts.
• Classrooms and places of worship that require intelligibility and rejection of ambient noise.
• Corporate AV environments and integration with automatic mixers .
