Manual-4

Both channels simultaneously: If you’ve selected both

channels (both CHAN LEDs on), the LED display shows the

smaller of the two channel’s current Delay values. Changing

this value changes the other channel’s value by the same rela-

tive amount. Check the other channel’s current Delay value by

selecting it with the CHAN button. ere are two things to be

careful of at this point: e ﬁrst is to pay close attention to the

CHAN LEDs that indicate the channel you are viewing, it cycles

from CHAN 1 to CHAN 2 to both and back again. (both always

displays the lower of the two channel’s current Delay values.) e

second gotcha at this point is pressing the RECALL button. is

writes over the changes you’ve made if you have not stored them.

STORING DELAYS

Press the STORE button. e STORE LED stops ﬂashing.

is Stores the current Delay values into each channel’s cur-

rent Memory (A or B). e current Memory for each channel is

indicated by the MEMORY LED which is lit when editing that

channel. Both channel's current Delay values are Stored with each

press of the STORE button.

RECALLING DELAYS

Press the RECALL button. Each press of this button al-

ternately Recalls stored Memories (A then B then A…) for the

selected channel only.

Tip: To recall Memories into both channels simultaneously,

store both channel’s values into the same Memory– A or B. With

both channels selected (both CHAN LEDs on), pressing RE-

CALL causes both channels to Recall the same Memory.

REMOTE RECALLS

e rear REMOTE RECALL terminals are functionally

equivalent to the front panel RECALL button. When the switch

closes, Memory B is recalled. Memory A is recalled by opening

the switch. ese terminals can not be locked out. When both

channel’s terminals are wired with a single switch for Stereo

operation, channel 1 is displayed.

Tip: Note the weather forecast for your event’s time of day. Set

up Memory A’s Delay value for your stack’s distance at one tempera-

ture, and Memory B’s value for a diﬀerent temperature. en dur-

ing the warmer part of the day, recall Memories to suit the climate.

INTERNAL BYPASS JUMPER SETTING

Internal jumpers enable or disable the BYPASS buttons while

in Front Panel Lockout mode. e default setting of these jump-

ers disables the BYPASS buttons in Front Panel Lockout mode.

(See enclosed drawing 103473.)

HOLE PLUGS

Once your system is properly conﬁgured, the SENSITIV-

ITY knobs can be removed and the unit secured by replacing the

knobs with the provided hole plugs.

AD 22d CONNECTION

When connecting the AD 22d to other components in your

system for the ﬁrst time, leave the power supply for last. is

gives you a chance to make mistakes and correct them before

any damage is done to your fragile speakers, headphones, ears,

or brains. e AD 22d passes audio while it is unpowered by

virtue of its fail safe bypass relays (when the AD 22d functions

as a wire). Turn the system volume down before plugging in the AD

22d’s power.

INPUTS AND OUTPUTS

e AD 22d’s Inputs and Outputs are electronically bal-

anced, so use only balanced wiring. e AD 22d’s shields (pin 1)

connect to chassis ground. Pin 2 is “hot” per AES standards.

REMOTE RECALL TERMINALS

Each channel of the AD 22d has two nonvolatile Memories,

“A” and “B”. Connecting a switch between the GND and CH1

or CH2 terminals permits recalling the Memories remotely.

Only a change in the switch position is sensed—when the switch

closes, Memory B for the given channel is recalled. When the

switch opens, Memory A is recalled. Connecting the two chan-

nel terminals (CH1 & CH2) together on one side of the same

switch, permits stereo recall of Memories A and B.

OPERATING INSTRUCTIONS

Once you have properly connected the AD 22d to the

system, turn on the power. When the AD 22d is ﬁrst powered it

displays the words “RANE” and “Ad 22”. en, the unit’s software

revision level is brieﬂy displayed.

e ﬁrst time you power the AD 22d it is in BYPASS, and

functions like an expensive wire. is is useful for initial trouble-

shooting and allows veriﬁcation of signal ﬂow.

THE BASICS

e AD 22d is a two channel device. Each channel has a

current Delay value that is always active/heard. You can only

edit the current Delay values in each channel, which can then be

stored in either of two nonvolatile Memories, A and B.

SENSITIVITY SETUP

e ﬁrst step is to apply signal, and adjust the SENSITIV-

ITY controls. If you know the nominal level, adjust the control

so its indicator points to that level. Otherwise, set the SENSI-

TIVITY control so high signal peaks just illuminate the CLIP

indicator, then back oﬀ a little.

ADJUSTING CURRENT DELAY VALUE

One Channel at a time: Press the CHAN button to select

the desired channel. e LED display shows the current Delay

value of the selected channel. Press the up/down buttons until

the desired Delay value is reached. at’s it! Press the CHAN

button until the other CHAN LED is lit and edit its current

Delay value.
