The AR-960D AirLink Line Level Wireless Audio Router System with Digital Delay from TeachLogic transmits audio via an RF signal to a receiver. The system comprises the ALS-960 Wireless Base Station Transmitter and DR-702 Diversity Receiver. The transmitter will broadcast the audio signal to a distant AirLink receiver or multiple receivers. The output of the receiver can be fed to the line input of a remote sound system or transmitted to a portable sound system with a wireless receiver.
The AirLink system operates in the UHF range (640 to 664 MHz) and has 96 selectable preset channels. The transmission distance between the base unit transmitter and the receiver can be in excess of 500' (152.4m) (direct line of sight).
The input to the ALS-960 Wireless Base Station Transmitter is line level audio. Two line level audio signals can be input and mixed in the transmitter for a composite signal transmission. The output level of each input can be adjusted and turned on/off. The output of the unbalanced line input can be monitored with a headset. The RF output is 30mW.
The transmitter also functions as a handy 2-channel mixer by combining the Aux line level input and the 1/4" mic input. This allows both pre-recorded program material and a live microphone to be broadcast at an event with no additional mixing equipment required.
The DR-702D Diversity Receiver has a half-wave antenna for extra sensitive reception. The output of the receiver is either balanced (XLR) or unbalanced (RCA) and is adjustable from 0 to 700mV. The DD-702 Digital Delay Module synchronizes distant audio speakers with the program audio location. It delays the output signal of the receiver by 20 to 500ms. The delay module features an LCD that displays the delay time in milliseconds.
The ALS-960 AirLink Stand Alone 96-Channel Transmitter from TeachLogic operates on the 640 to 664 MHz band and has 96 available channels to select from. It can be incorporated with the diversified receiver for transmission of a composite program for an extended distance in excess of 500.0’ (152.4m) with clarity and reliability.
The TeachLogic DR-702D AirLink Standalone 96-Channel Receiver with DD-750 Digital Delay Module operates in the UHF range (640-664 MHz) to receive RF audio signals from the ALS-960 transmitter. The system has 96 selectable preset channels.
The receiver is a diversity receiver, meaning the signal will be received by either of two receivers; whichever has the best reception. Each receiver has a half-wave antenna for extra sensitive reception. The receiver has both balanced (XLR) and unbalanced (1/4" phone jack) outputs.
The receiver features the DD-750 digital time delay module that synchronizes distant audio speakers with the program audio location. It delays the output signal of the receiver from 20 to 500 ms. The LCD displays the delay time in milliseconds.
