AVer COMVCSPK2 – VC520/VC520+ Daisy-Chain Speakerphone

Product Overview

The AVer COMVCSPK2 is a daisy-chain speakerphone designed to expand the audio coverage of the AVer VC520 and VC520+ video conferencing systems. It adds a dedicated 360-degree pickup zone to an existing VC520 speakerphone without requiring a separate audio interface or additional software. Whether you're extending coverage to the far end of a boardroom table or filling in a secondary seating area, the COMVCSPK2 integrates directly into your existing VC520 chain using the included color-coded Cat cable. For organizations that rely on AVer's VC520 platform, this unit is the straightforward path to larger-room audio without replacing existing equipment.

Product Description

The AVer COMVCSPK2 daisy-chain speakerphone connects to an AVer VC520 or VC520+ conference system to extend the voice-pickup radius from a single unit's 15-foot range to 30 feet when one expansion unit is added. Add a second COMVCSPK2 to reach a maximum 45-foot voice-pickup radius across three speakerphones in total — covering even the largest mid-to-large conference rooms. The unit operates in full-duplex mode, meaning both sides of a call can speak and be heard simultaneously without audio clipping or dropout, which keeps conversations fluid and natural.

Every button on the COMVCSPK2 mirrors the controls on the primary VC520 speakerphone. Participants seated near the expansion unit can mute or unmute the call, adjust volume, answer, or hang up without walking to the main unit. The yellow color-coded 10-meter cable included in the box simplifies cable management and installation identification in multi-cable AV environments. Connection is handled via RJ45, and no drivers or configuration software are required — the unit is recognized automatically when plugged in.

The COMVCSPK2 is the correct expansion accessory for the original VC520 and VC520+ systems. For the VC520 PRO and VC520 Pro2, see the AVer COMEXPSPK expansion speakerphone, which uses a different connector standard.

Key Features

• Daisy-Chain Expansion — Connects to the VC520 or VC520+ speakerphone via included RJ45 cable; up to two units can be chained for a 45-foot total voice-pickup radius.
• 360-Degree Microphone Pickup — Omnidirectional pickup pattern captures voices from all directions within a 15-foot radius per unit, eliminating dead spots around a conference table.
• Full-Duplex Audio — Both ends of the call can speak simultaneously without clipping, providing natural conversation flow in conference room settings.
• Full Speakerphone Controls at Every Unit — Mute/unmute, volume up/down, call answer, and call hang-up are accessible at each expansion speakerphone in the chain.
• Color-Coded 10-Meter Cable Included — Yellow cable simplifies identification and installation in multi-device AV setups.
• No Software or Drivers Required — Plug-and-play connection to the VC520/VC520+ speakerphone; no configuration needed after physical installation.
• Compatible with VC520 and VC520+ Systems Only — Designed specifically for the original VC520 platform; ensures full feature compatibility and clean integration.

Typical Applications

• Mid-to-Large Conference Rooms — Extend microphone coverage along long boardroom tables where the base speakerphone alone does not reach all participants.
• U-Shaped or L-Shaped Meeting Rooms — Place expansion units at secondary seating areas to maintain consistent audio quality across non-linear room layouts.
• Training Rooms — Support larger participant counts by chaining two COMVCSPK2 units for full 45-foot coverage.
• Executive Boardrooms — Provide full speakerphone control to multiple points in the room without requiring participants to reach a single centralized unit.
