HLS-71 Series
Intelligent Surround Sound Switcher
User Manual

Introduction
The HLS-71 Intelligent Audio Switcher controls multi-channel audio systems between two sets of outputs. This
device also monitors system health, with optional network control and monitoring capabilities.
Features
• Switches up to seven channels of High-Level audio
and one LFE audio channel between two outputs.
• Measures input voltage, current draw, and peak
current draw for device health monitoring.
• Optional IP version (HLS-71-IP) enables remote
access to device functions, conguration, and event
logs.
• Firmware updated via microSD.

Communication
The HLS-71 Intelligent Audio Switcher has the default device ID 7. It can send and receive serial commands via
RS-485 at 57600 Baud, 8-N-1, and half-duplex; and via RS-232 at 115200 Baud, 8-N-1, and full-duplex. Both
conguration ports utilize a modular RJ-45 jack with the following pinouts:
RS-485 Pinout: RS-232 Pinout:
Pin # Function Pin # Function Pin # Function Pin # Function
P1 Orange White = ground P5 Blue White = switched

Tips and Guidelines
• Enable or disable multiple outputs with one command. Example: [DEV+7;ANALOG=1,3,5,7,9;ON]
• Only one speaker pair per channel can be active at one time, and switching between pairs will disable the
previous pair. For example, if Front A speakers are enabled, and then the Front B speakers are selected, the
HLS-71 automatically disables the Front A speakers before switching.
• Left and Right channels are enabled simultaneously for Front, Rear, and Surround speaker channels.
• To provide stereo audio from any channel, enable multi-channel stereo output on the amplier or bridge your
inputs. The HLS-71 does not distribute stereo audio to multiple outputs on-board.
• Follow all commands with a carriage return.

Quick Start Instructions
• Connect the receiver harness from “Speaker Level Input” on HLS device to AVR outputs.
• Connect the speaker harness from the “Left/Right/Center Speaker Output A/B” connections
• on the HLS device to the appropriate speakers.
• Open a serial terminal - 115200 8-N-1. Toggle Null/Straight switch if needed to correct signal polarity.
• Send analog switch commands to device 7 (default) to enable or disable a position.
Troubleshooting
No RS-232 Communication:
• Connections are fully seated.
• Devices are using the correct protocol settings.
• Null/Straight selector is set correctly.
No Ethernet Connectivity (IP version only)
• Connections fully seated.
• The end device is powered on, with Ethernet enabled.
• Power cycle all devices to clear out previous TCP connections.

Example System: HLS-71-IP With Speakers and Subwoofers
This display uses audio to attract and communicate. It leverages the HLS-71-IP module’s high level audio output
options to demonstrate two different products. All audio outputs can play either digital or analog audio, depending
on the requirements of the device. The Ethernet port interfaces with the network to receive commands and output
analytics; with the added capability to control and monitor the system remotely. The HLS-71-IP receives power via
an MH2-4K media hub.

Firmware Updates
• The HLS-71 series is updatable through the microSD port utilizing a card with FAT-32 formatting (preferred).
Below are the steps outlining the rmware update process:
• Copy new rmware “.FWU” le onto a blank microSD card (FAT-32 format preferred). Insert Firmware Update
SD into the device with device power disconnected.
• Apply power to device, monitoring the power LED Indicator.
• When power LED indicator returns to a slow blink, update is complete.
• To verify the rmware update, send the rmware version query listed in the Commands List (see above) and
ensure response matches the rmware version expected.
