Dual Zone 100V Mixer-Amplifier 2 x 240W

Dual Zone 100V Mixer-Amplifier 2 x 240W

Overview

The Adastra V‑242 is a versatile, dual‑zone mixer‑amplifier engineered for public address and distributed audio systems. It provides 2 × 240 W RMS output via either 100 V line or low‑impedance (4-8 Ω) speaker outputs, and features multiple input sources including Bluetooth, DAB+/FM receiver, and USB/SD media playback. Ideal for installations in retail, leisure, hospitality or corporate environments where flexible zoning and media input options are required.

Design and Build Quality

• Class‑D amplifier module housed in a full‑size 19‑inch rack mount chassis.
• Robust front and rear panel I/O: combination XLR/jack/screw inputs for mic/line channels, plus line-level RCA and 3.5 mm (aux) jack inputs.
• Integrated media player with Bluetooth Version 5.0, USB & SD card slots, and built‑in DAB+/FM tuner.
• Rotary source selectors per zone for switching between line inputs, the aux source or internal media player; includes independent tone controls (bass & treble) per zone for sound tailoring.
• Solid speaker output connections using screw terminal blocks; standard IEC mains inlet with universal supply from 170‑264 Vac, 50 Hz.

Key Technologies and Features

• Dual Zone Output: Two independent zones, each capable of driving 100 V or low‑impedance loads, or both simultaneously if required.
• Multiple Inputs: Three balanced mic/line inputs with phantom power & priority on Channel 1; additional line-level inputs (RCA / Aux / stereo source).
• Media Integration: Built‑in DAB+/FM, USB/SD playback, Bluetooth v5.0 -- enabling wireless streaming or playback from USB/SD cards.
• Flexible Controls: Zone‑by‑zone source selection, front jack inputs, rear combo connectors; priority switching for announcements; tone control per zone.
• Expandability: Line‑level zone outputs allow cascading or feeding additional amplifiers, enabling large‑scale audio systems.

Performance and User Experience

In operation, the V‑242 offers clean, powerful amplification with clear audio for both speech and music. Zone separation allows independent control over two areas, so differing volume or source needs can be met without compromise. The integrated media player and Bluetooth functionality offer flexibility for non‑technical users to manage playback easily. Tone controls enable tailoring to venue acoustics, and the priority input ensures announcements can override other audio when required.

Q&A Section

• Q: Can I run passive 4‑8 Ω speakers instead of 100 V line speakers?
  A: Yes. The unit supports either 100 V line or low impedance (4‑8 Ω) speaker outputs on each zone, offering flexibility in speaker choice.
• Q: Does it support phantom power for condenser microphones?
  A: Yes. Phantom power (approximately +20 V) is switchable to the mic XLR inputs, allowing use with condenser mics where needed.
• Q: How do I override music for announcements?
  A: There is a priority feature on Channel 1. When this channel is active (e.g. from a mic input), it will override other input sources to ensure announcements are heard clearly.
• Q: Is it possible to link or extend the system with additional amplifiers?
  A: Yes. The unit has line‑level outputs for each zone, enabling connection to further amplifiers if you need to scale the system beyond the onboard power rating.
• Q: What are the media source options?
  A: You have a variety: USB/SD card slots, built‑in Bluetooth 5.0, internal DAB+/FM tuner, plus auxiliary line and stereo line inputs.
