Self Amplified Digital Keypad with Bluetooth and Analog Inputs

INTRODUCTION

This Self-Amplified Digital Keypad features a 6 watts/channel amplifier, a Bluetooth
audio receiver, and three analog audio inputs. It provides an easy to connect central
location for playing back audio material from a variety of portable sources. IR repeater
functionality allows a remote source device to be controlled using its standard IR remote
control.

SAFETY WARNINGS

1. This device is intended for indoor use only. Do not expose this device to water or
moisture of any kind.

2. Ensure that the wire connections are clean, with no stray wire strands anywhere.

3. Double check all connections before applying power.

4. Do not provide a speaker load lower than 4 ohms to the amplifier. Doing so can
cause damage to the amplifier and could result in a fire.

5. Do not install or operate in close proximity to a heat source, such as a furnace,
radiator, or fireplac e.

CONNECTION NOTES

The Bluetooth Audio receiver and the 2x RCA stereo analog jacks are in parallel. If an
audio source is applied to both inputs they will be mixed with higher volume levels.

The 3.5mm TRS jack and the internal hard wired terminals are also in parallel. If an
audio source is applied to both inputs they will be mixed with higher volume levels.

The 3.5mm jack/hardwired terminals have priority over the Bluetooth/RCA inputs. If an
audio source is present on both the 3.5m m/h ar dwired input and the Bluetooth /R CA
input, only the source(s) from the 3.5mm/hardwired input will be heard.

Note that combining audio sources in this way is not recommended and could cause
damage to your equipment. The only proper way to mix audio signals is using an audio
mixer. Therefore we highly recommend against applying an audio signal to both the

3.5mm and hardwired inputs. Similarly, we recommend to not use both the Bluetooth
receiver and RCA jacks at the same time.

INSTALLATION

1. Connect a pair of speaker wires from the installed speakers to the OUTPUT terminal
block on the device. Pay close attention to left/right orientation and ensure that the
+/- polarity is properly maintained.

2. Obtain a 24 VDC power source (not included). Connect the positive output of the
power source to the V+ terminal and the negative output to the G terminal. Once
power is applied the unit will be in standby.

3. (Optional) If you intend to use the IR repeater functionality, connect the positive wire
from an IR Transmitter/Emitter to the IR OUT + terminal and the negative wire to the
IR OUT - terminal. Position the IR bulb so that it can "see" the IR receiver on your
source device(s).

4. (Optional) If you want to make a hardwired internal connection, connect the audio
source right channel positive to the R+ terminal. Connect the audio source left
channel positive to the L+ terminal. Finally, connect the audio source negative wires
to the G terminal between the L+ and R+ terminals.

5. Test the unit to ensure that all inputs and outputs are operating properly. Check the
balance of the speaker volume. If it is not in proper balance, you can adjust the
balance using the Bala nce Tri m Pots on the bac k of the amplifier.

6. Mount the plate as desired. After it is secured in place, install the front cover to hide
the installation screws.

OPERATION

1. Press the power button on the device to turn it on. The orange backlight behind the
digital display will be illuminated when power is on.

2. (Optional) Establish a Bluetooth connection between your mobile device and the
amplifier unit by perfor mi ng the foll owing steps:

2a. Ensure that your Bluetooth capable device is within 3 feet of the

amplifier/Bluetooth Receiver.

2b. Initiate the pairing procedure on your Bluetooth capable device. You should see

an Audio Adapter XXXX, where XXXX is the 4-digit number on the audio
adapter. If you do not see the audio adapter device entry, turn off the digital
keypad, wait 30 seconds, then power it back on. Wait another 5 seconds and y ou
should see the Audio Adapter XXXX entry in the list of available Bluetooth
devices.

2c. When asked to input the passkey or PIN code, enter 6728. This passkey shoul d

only be needed the first time you connect to the keypad. The keypad remember
up to 8 Bluetooth pairings and will automatically reconnect to a previously paired
device.

3. If the audio source is not already hardwired to the keypad or is not connected via
Bluetooth, connect it to the keypad using the 3.5mm or 2x RCA connections.

4. With the volume turned all the way down on the audio source device, press the
volume up button on the keypad until the numeric display reads at least 20. The
volume on the keypad has 31 steps, so 20 represents about 2/3ds of maximum
volume.

5. Next, increase the volume on your audio source device until it is at your desired
listening level. From this point, the keypad can be used to increase or decre as e
volume without needing to adjust the volume on the source device.

INPUT LEVEL SWITCH

The Hi-Lo Input Level Switch is used to adjust the input sensitivity of the amplifier.
The LO setting is designed for a 200mV input signal. If the audio source is from the

headphone output of a mobile device, use the LO setting.
The HI setting is designed for a 1.0V input signal. If the audio source is from a standard

audio component (e.g., DVD player via RCA), use the HI setting.
