Amplifier Module (HB-1S)

he HNB amplifier module HB-1S is included with HNB-A. It always plugs into

the RIGHT SLOT (J2) of HNB-A and provides high fidelity Stereo and Mono

audio (digital class-D power) to any 4- or 8-ohm speakers. The HNB amplifier

will support 70V speakers using

SonicDevices HNB-70V2X matching impedance

transformer unit that may be ordered separately (see page 24, section 5.2).

Module Features:

• Robust digital class-D architecture with better than 85% efficiency.

• Dual channel 25W into 4-ohm / 12W at 8-ohm operation.

• Mono or stereo operation with full bandwidth operation 20Hz - 20kHz.

• Fits into standard 2-gang electrical box (3.5”DEEP) with Decora wall plate.

• Automatic over current and over temperature protection.

• Manual front volume controls for R+L channels.

• IR control of each channel’s volume, bass, treble, balance (See HB-IR).

• Visible active power status LED’s for each channel (Green).

• Powered via HNB backplane at 24VDC from one UL/Energy Star listed

wall power supply.

Preamplifier Module (HB-2PA)

The HNB preamplifier module HB-2PA is an integrated, high fidelity audio

mixer that can be used in the LEFT SLOT of EITHER the HNB-A or the HNB-B

chassis. It provides multiple balanced line inputs at nominal 1V/600 ohm line

level (A+B+C) via phoenix, RCA and 3.5mm connections that can be selected

via IR remote control or a manual front slide switch.

Audio inputs can be shaped for greater intelligibility via front accessible controls for

treble, bass and volume. Inputs may be mono or stereo and are automatically rout-

ed to the HB-1S amplifier SPEAKER 1 (R) + SPEAKER 2 (L) and AUDIO LINE

OUTPUT (J7) on the rear backplane. An internal audio input connection used for

audio or microphone input has a ducking control (0dB to -50dB) which automatical-

ly ducks the ‘B’ + ‘C’ audio sources when voltage is present from the HNB-C RJ45

microphone input.

Module Features:

• Stereo or Mono operation at full bandwidth of 20Hz - 20kHz.

• Multiple audio source inputs via common phoenix, 3.5mm, RCA terminations.

• Audio source selection via front slide switch (A+B+C).

• Fits into standard 2-gang electrical box (3.5”DEEP) with Decora wall plate.

• AM/FM ‘RF’ and audible noise suppression.

• Signal to noise at 85dB and sensitivity at -16dBu.

• Manual front volume controls for audio and HNB-C microphone channels.

• IR control of each channel’s volume, bass, treble, balance (see HB-IR).

• Independent automatic duck control of all audio when HNB-C RF

Wireless microphones are used (voltage sensitive).

• Visible active power status LED (Green).

• Powered via HNB backplane at 24VDC from one UL/Energy Star listed

wall power supply.
