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 88 Headset wireless system Physically place the CR88 receiver where it will be used, and extend the antennas vertically. The general rule of thumb is to maintain a “line of sight” between the receiver and transmitter so that the person using or wearing the transmitter can see the receiver. With the CR88 powered off, connect the included power adapter. Turn the CR88 on momentarily to confirm that the unit is receiving power. You’ll see the LED display light up. Then turn the CR88 power off. With your amplifier or mixer off and volume control all the way down, connect the CR88 receiver output jack to the mic or line level input of a mixer or amplifier using the balanced XLR output or unbalanced ¼” line level output. Turn the Level knob on the CR88 completely counterclockwise, then turn its power on.

Press the SELECT button on the front of the CR88 receiver to choose an available channel. The channel number will increase by one digit, from 0-9 then A-F. Once the last channel has been reached, the count will cycle back to 0.

Make sure the AH8 Headset transmitter is fully charged (see section Charging the  AH8 Transmitter) Turn on the power to the transmitter by pressing and holding the Power button for 3 seconds; the indicator LED will light yellow when the button is pressed and turns green when released and the AH8 is powered on.

Position the transmitter about 6-12” (15-30 cm) from the front of the CR88 with the transmitter’s IR window facing the IR transmitter on the front panel of the CR88 receiver. Press and hold the CR88 SELECT button to set the transmitter to the same channel as the receiver via infrared transmission. The CR88 display will flash while the receiver is sending the operating channel .SAMSON-AirLine-88-Headset-Wireless-System-fig-4

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 CR88 will receive an RF signal from the transmitter. The READY indicator will light on the front panel of the CR88 receiver.

Turn on your connected amplifier or mixer, but keep the volume all the way down. Set the Volume knob on the CR88 fully clockwise (to its “10” setting). This is unity gain. Speak or sing into the microphone. 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. 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 owner’s 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 CR88 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 receiver to ensure that the transmitter is not accidentally reset.

Charging the AH8 Transmitter

SAMSON-AirLine-88-Headset-Wireless-System-
fig-8

  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.

  5. 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.

  6. 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.

Getting the most out of the rechargeable battery:

  • Completely charge the batteries before first use
  • Fully charge the battery before it will be used.
  • After the battery is charged, unplug the charger from the outlet or remove the battery from the charger.
  • The optimal temperature range for using and storing the battery is 50°F – 86°F (30°C – 50°C). The battery performance and operation may decrease in temperatures below 50°F (30°C).

warning that batteries (battery pack or batteries installed) shall not be exposed to excessive heat such as sunshine, fire, or the like.
CAUTION: Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type of 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. To help reduce p-popping, install one of the (4) included windscreens.
Note: If wearing glasses, it is recommended to put the AH8 transmitter on first then place glasses over the transmitter. If the AH8 headset is too large, push the sides of the headband in to decrease the width. If the transmitter is too small, pull the sides of the headband out to increase the width.

Warning: The ear hooks are NOT adjustable. DO NOT bend the ear hooks as this will damage the headset.

Cleaning the AH8 transmitter:
The headset, microphone, and gooseneck should be cleaned after each use. Use clean, fresh water on a towel or clean rag, gently wiping away any contaminations that may have accumulated during use. The windscreens should be washed with clean water after each use.

Rack Mounting

  • The CR88 receiver can be installed into a standard 19” rack for transport or permanent installation using the included rack ears. Follow the simple steps below to mount the CR88:
  • Attach the included rack ears by sliding each rack ear into the groove on either side of the CR88 until they lock into place and the receiver is flush with the front panel.
  • Position the CR88 receiver into an available rack space and slide in until the rack ears are touching the rails of the rack case and are aligned with the rack rail holes.
  • Mount the receiver into the rack using the appropriate size rack screws (not included). To ensure equal tension and balance when installing the receiver, you should secure screws in a crisscross pattern of opposite corners: top left -> bottom right -> top right -> bottom left.

In order to mount two CR88 receivers in one rack space, the system includes a center connection piece. Slide the center connection piece into the groove of each receiver and attach the short rack ears to each receiver. Mount the receivers into the rack using the crisscross pattern described above. Note: Receivers should be mounted in the top rack position with additional audio units mounted below. Digital audio devices should be mounted as far as possible below the CR88 receivers.
