Quick Start

In order for your wireless system to work correctly, both the receiver and transmitter must be set to the same channel.

Follow this basic procedure for setting up and using your AirLine 88x Headset wireless system:

Physically place the CR88x receiver where it will be used, and extend the antennas vertically. The general rule of thumb is to maintain “line of sight” between the receiver and transmitter so that the person using or wearing the transmitter can see the receiver.

With the CR88x powered off, connect the included power adapter. Turn the CR88x on momentarily to confirm that the unit is receiving power. You'll see the LED display light up. Then turn the CR88x power off.

With your amplifier or mixer off and volume control all the way down, connect the CR88x receiver output jack to the mic or line level input of a mixer or amplifier using the balanced XLR output or unbalanced 1/4" line level output. Turn the Level knob on the CR88x completely counterclockwise, then turn its power on.

Press the SCAN button for more than 2 seconds (the display will start to flash quickly) on the front of the CR88x receiver to scan for an available channel. Once the optimal channel is selected the receiver will enter IR Set mode. The display will flash slowly in IR Set mode.

If you want to set a transmitter to the receiver's currently selected channel, press and hold the SCAN button for more than 10 seconds (until the display flashes slowly) to enter IR Set mode directly.

SAMSON R VOLUME BEEF PWM 0.7 ECOM POWER

Note: The AH8 will only accept infrared transmission from the receiver for the first 10 seconds after the AH8 is powered on. If you need to change the operating channel, the AH8 must be first powered off, then powered on again to receive the new channel.

When the transmission is complete, the CR88x will receive RF signal from the transmitter. The READY indicator will light on the front panel of the CR88x receiver.

CR SAMSUNG SAMSON 0.1 R SCAR POWER

Turn on your connected amplifier or mixer, but keep the volume all the way down. Set the Volume knob on the CR88x fully clockwise (to its "10" setting). This is unity gain.

Speak or sing into the microphone and slowly raise the volume of your amplifier or mixer until the desired level is reached.

If you find the system has noticeable dropouts, reduced overall working range, or unexpected noise bursts, change the operating channel of the system using the steps above.

Quick Start

It is recommended to use one of the included foam or stainless steel windscreens when using the AH8 headset. This will help reduce breath or wind noise.

To attach the stainless steel windscreen, line up the windscreen with the end of the microphone capsule and push straight on until it is securely affixed.

If you hear distortion at the desired volume level, check to see whether the PEAK Indicator LED on the receiver is lighting RED. If it is not lit, make sure that the gain structure of your audio system is set correctly (consult the owners manual of your mixer and/or amplifier for details). If the PEAK Indicator on the receiver lights RED, it may be as simple as moving the microphone further from your mouth.

If the level of the microphone needs further adjustment, press and hold the AH8 “+” or “-”

level buttons until the indicator starts flashing indicating that the transmitter is in the Volume Adjustment mode. Press the “+” button to raise the level or the “−” button to lower the level. As the level increases the indicator flashes faster. When the level decreases the indicator flashes slower. When the desired level is reached, release the volume buttons. The AH8 will return to normal operation after 10 seconds, and the Status Indicator will be steady GREEN.

For best signal to noise performance, set the AH8 transmitter volume so that the PEAK indicator on the CR88x receiver flashes occasionally when speaking or singing with your loudest voice.

Multiple System Setup

When using multiple systems, each system must be set to a different operating channel. Transmitter and receiver pairs must be on the same channel plan in order to work together.

When setting an additional transmitter, make sure to move all other transmitters away from the CR88x receiver to prevent setting multiple transmitters to the same channel.

Charging the AH8 Transmitter

1. Snap in place the appropriate mains connector plug into the adapter.

2. Insert the magnetic power cable to the included USB AC plug (or any 5-volt DC adapter that has a USB port). Insert the AC plug into an electrical outlet.

3. Place the AH8 transmitter on a flat surface.

4. Attach the magnetic connector to the gold contact power port on the bottom of the AH8 transmitter. The cable attaches to the port magnetically. The magnetic connector is keyed so it will only connect in one direction.

Note: Transmission is disabled during charging.

1. Look at the indicator light on the AH8 transmitter to determine when the transmitter has finished charging. When the light is flashing red, the AH8 is charging. When the red light stops flashing it indicates that the AH8 is fully charged.

2. Disconnect the magnetic power cable from the AH8 when the unit is fully charged.

If you notice your AH8 battery life is becoming shorter after a full charge, you can order a user replaceable battery from your local Samson distributer.

CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type attention should be drawn to the environmental aspects of battery disposal

Wearing the AH8 Transmitter

The AH8 can be re-sized to fit comfortably on your head. The correct way to wear your AH8 Headset transmitter is over the ears, as you would wear a pair of eyeglasses. Because the AH8 Headset is specially designed to be used up close, be sure to position the microphone near the corner of your lips. To avoid feedback problems, take care not to cover the mic capsule with your hand.

Position the AH8 over your head so that the body of the transmitter is behind your head. Adjust the headset so that it fits comfortably on your ears and is secure against your head.

Position the microphone towards the corner of your mouth, approximately 1/2" away from the lips.
