FEATURES AND CONTROLS – FRONT PANEL
-
Power On/Off and Indicator
Main power switch, the indicator light when the amplifier is turned on. -
MIC1, MIC2, and AUX Volume Controls
Adjust the output signal level of the corresponding inputs. -
BASS and TREBLE Tone Controls
Adjust the bass and treble of the corresponding inputs. -
MIC1 and MIC2 Inputs
To connect the low impedance microphone with a 1/4″ plug. The MIC 1 is a ” Priority” source, the signals from AUX will be attenuated automatically by -40dB, and the signal from MIC 1 will override to page (auto talk-over). it is good for a paging system. -
AUX Input
To connect the high-impedance audio source such as Tape Deck, CD player, or Tuner with a 1/4″ plug via an audio plug adapter (two phono RCA plugs into a 1/4″ mono jack). -
BT/LINE Input Switch (For PCM21BT only )
Press in, its Bluetooth Input status, and press it out, its LINE input status. -
Bluetooth Indicator
-
Bluetooth Antenna (For PCM21BT only)
The antenna is the best receiver for Bluetooth signals. -
Voltage Switch
This PA amplifier has a selectable input voltage from 110V/60Hz ( the standard in USA and CANADA ) to 220V/50Hz ( for EUROPEAN operation). Please make sure the switch is in the proper position before operating, otherwise severe damage will be incurred and not covered by warranty. -
AC Input
Plug the included power cord into the unit while the power is switched off, then plug the AC power cord into a proper power outlet. Please also replace the fuse only with the proper rating if needed (see the fuse rating of T 1.2AL 250V for 110-120V and T0.63AL 250V for 220V/240V printed at the power inlet) -
Speaker Connection
One or more speakers (4,8 or 16 Ohms) can be connected to the amplifier with or without transformers. However, before you connect any speakers to the amplifier, the total impedance must be calculated in order to avoid damage to the amplifier. A total speaker impedance greater than 8 Ohms or less than 8 Ohms can cause this damage to occur.
SPEAKER CONNECTION
One or more speakers (4, 8, or 16 Ohms) can be connected to the amplifier with or without transformers. However, before you connect any speakers to the amplifier, the total impedance must be calculated in order to avoid damage to the amplifier. A total speaker impedance greater than 8 Ohms or less than 8 Ohms can cause this damage to occur.
SYSTEM 1: Single Speaker System
NOTE: Connect the speaker (+) to the amplifier’s 8-Ohm terminal.
SYSTEM 2: Two (or more) Speakers in Series
NOTE: Connect the speaker (+) to the amplifier’s 8-Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance of 4-Ohm, the total speaker impedance in this series configuration is 8 ohms.
SYSTEM 3: Two (or more) Speakers in Parallel
NOTE: Connect the speaker (+) to the amplifier’s 8-Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance of 16-Ohm, the total speaker impedance in this series configuration is 8 ohms.
SYSTEM 4: Four Speakers in Series and Parallel
NOTE: Although the description above is for connecting two series pairs of 8 Ohms speakers in a parallel hook-up, you may also select to combine a series pair and a parallel pair in a parallel hook up, simply be sure you have calculated the total impedance, and attach the speaker (+) circuit wire to the proper amp terminal.
SYSTEM 5: Connecting Speakers with Transformers
NOTE: When the 25V or 70V constant line voltages are used, a line- matching transformer must be used with each speaker, All transformers must be connected in parallel, never connect line transformers in series.
BLUETOOTH OPERATION INSTRUCTION (For PCM21BT only)
External devices which have a built-in Bluetooth feature can be connected to this amplifier wirelessly to play through the amplifier’s speakers. If your amp is connected to speakers, you will hear audible tones which will help for connecting.
- First, be sure that the amplifier is powered on, and turn the volume to low. Please remember to connect the Bluetooth Antenna at the back panel for a better-receiving signal
- Press the BT/Line button switch in on the front panel, and you will hear the voice “POWER ON” and also “PAIRING”, and then the unit is automatically ready to pair with your external device.
- Turn on the Bluetooth of your external device.
- Search for available Bluetooth devices and make sure to be within range of your amp, and wait for your device to select “BT-RY” on the pairing devices lists of Bluetooth networks.
- Once connecting you will hear a voice say, “Your Device is Connected”, then the Bluetooth pairing is successful and you have established a Bluetooth connection.
- You can now play music on your external device through the amplifier.
