The Signet PRO11/DD dual loop, phase shifted induction loop amplifier is ideal for larger installations, especially where large amounts of metal are present. With its output current of 2 x 7.5 Amps, it’s suitable for rooms up to 1000m².

The OLED display on these ‘PRO’ amps offer a more detailed display than the PDA version.

To ensure uniformity of the magnetic field, a phased array system produces two AFILS signals 90° out of phase with each other. These signals are connected to two identical hearing loops laid in a special overlapping pattern. The resultant magnetic field is evenly spread within the covered area but falls off quickly outside the loop. A phased array system eliminates 'dead spots' often found with a perimeter loop design and also prevents 'overspill' to adjacent rooms.

Three versions of this freestanding phase array loop amp are available;

• PRO5/DD - 2 x 3.25 Amps, 200m²
• PRO7/DD - 2 x 5 Amps, 500m²
• PRO11/DD - 2 x 7.5 Amps, 1000m²

Please note: The smallest practical room width for a phased array loop is 5m.

The OLED digital display panel indicates the operational status and any faults on the amplifier inputs, whilst the 4 control buttons are used for navigating the menu displays and adjusting the settings.
