When inserting the batteries, note the symbols in the battery compartment to ensure the power supply.

3 Close the battery compartment cover (9)

6.2 Connecting the antennas

The following antennas can be mounted on the receiver:

- / 4 antennas (included as standard)

For all applications where there is a line of sight between the transmitter and receiver antennas.

- Remote antennas

For applications where the reception conditions are not optimal at the receiver position.

To mount the /4 antennas, proceed as follows:

Step Description

1 Mount /4 antennas onto the front panel (13); use BNC front mounting cable (AKG part no. 0110E01890) to do this.

To mount the remote antennas, proceed as follows:

Step Description

1 Connect remote antennas with BNC sockets (14) and (15) to the rear of the receiver; use a RG58 cable to do this

More information on antennas, accessories and help on frequency planning can be found on our website at www.akg.com.

6.3 Position the receiver

Reflections of the transmitter signal on metal parts, walls, ceilings, etc. or shadows from human bodies can weaken or wipe out the direct transmitter signal.

For this reason, observe the following points when setting up the receiver or the remote antennas:

• Always position the receiver/antennas close to the action area (stage), ensuring a minimum distance between the transmitter and receiver/antennas of 3m to an optimal 5m
• Avoid shadows of the transmitter signal from persons or objects as these can interrupt the radio link. The requirement for optimal reception is the line of sight between the transmitter and receiver/antennas.
• Position the receiver/antennas at a distance greater than 1.5 m away from large metal objects, walls, platform structures, ceilings, etc.

The receiver can be set up either freestanding or in a 19" rack.

When installing one or more receivers in a 19" rack, the antennas supplied are mounted onto the receiver front panel or remote antennas are used. This is the only way to guarantee optimal reception quality.

6.4 Connecting the receiver to the mixing console/amplifier

The DSR800 receiver has the following outputs

• Analog outputs
• Digital outputs

XLR output

6.4.1 Analog outputs

Both analog XLR outputs (17, 20) and both analog 6.3 mm jack outputs (18, 21) can be connected at any time. The output level can be set accordingly in the AUDIO menu.

To connect the analog outputs, proceed as follows:

Step Description

1 BALANCED socket (XLR) to microphone input: Move the output level switch to the "-30 dB" position

14 Functional description

The DSR800 has been developed for operation in large multi-channel systems.

14.1 CHANNEL menu

This menu can be used to manually set all parameters relevant for a channel such as group/channel, frequency, name, input level of the bodypack transmitter, encryption and MUTE LOCK.

The DSR800 receiver provides frequency groups with specially calculated frequencies. The required channel (frequency) can be manually set and synchronized in this menu.

Ensure that all channels are selected from the same group within the same presets. To search for free channels, we recommend the QUICK SETUP function

The following table describes the functions of the submenus in the CHANNEL menu.

Submenu Function

FREQUENCY Set the frequency directly in 25 kHz increments

NAME Assign any name for each channel (name of a musician, instrument, or similar)

MIC GAIN Adjust the audio input level of the transmitter to the connected microphone

TRANSM. POWER Set the transmission power of the synchronized transmitter

Submenu Function

ENCRYPTION Activate the encryption function

When the encryption function is activated, the receiver calculates a one-off key every time a transmitter is synchronized. This key is sent to the transmitter during the synchronization process. The key is not displayed and it is not possible to send the same key to two transmitters.

Note:

For transmitters with firmware versions lower than 2.0, choose the 32-Bit encryption. (These transmitters do not function with 512 Bit encryption.)

For transmitters with firmware version 2.0 or higher you can achieve the highest possible security with 512 Bit encryption.

If you use a replacement transmitter for a channel, the encryption must be deactivated.

MUTE The MUTE LOCK function deactivates the MUTE switch on the transmitter

The transmitter synchronized with the receiver cannot be muted with the MUTE button.

The MUTE=POWER function allows the MUTE button of the transmitter to be used as the on/off switch as well.

SYNCHR. TRANSMITTER

Programming the transmitter to the receiver settings

GAIN Set input level of the DSP chain

Submenu Function

DSP Edit audio signal directly on the receiver
	Settings can be stored in one of the nine DSP profiles in a freely selectable name.The digital signal processor offers the following dynamic editing functions:Low Cut (frequency: 10 – 300 Hz)3-band equalizer (low: ±20 dB, 80 Hz shelving; parametric mid: ±20 dB, 100 Hz to 10 kHz, Q = 2; high: ±20 dB, 8 kHz shelving)dbx® compressor (threshold: -60 - +9 dBV, ratio: 1:1 - 1:10, gain: 0 – 20 dB, attack: 1 – 100 ms, release: 1 – 2000 ms)dbx® limiter (threshold: -20 – +9 dBV)Changes to a profile always affect both channels. All previous settings of a profile are overwritten.
ATTENUATION PAD	Modify the level of the balanced audio output to the input sensitivity of the connected equipmentWith microphone inputs, the setting 0 dB can result in overloads.If the receiver is connected to a microphone input, it is recommended to select -30 dB.The unbalanced line output cannot be controlled.
ENVIRONMENT SCAN	This function works in a similar way to a spectrum analyser.UNLIMITED SCAN: the entire frequency band of the receiver is searched for active radio frequenciesLIMIT SCAN: only a part of the frequency band is searched for active radio frequenciesDuring the search process, the audio output remains muted and the display shows the result graphically.Turn the SELECT wheel: Move the curve to the left or rightPress SELECT: Enlarge curve

Submenu Function

REHEARSAL Sound check

Check HF level of the transmitter in the action area

The maximum recording time is four minutes

UTILITY STATUS Activate optical warning function for specific critical operating conditions

If one of these operating conditions occurs, the light ring around the SELECT wheel on the receiver changes from green to red and a corresponding status display is shown on the display.

The light ring changes to red and the display shows a large warning for 5 seconds. A small warning remains on the display until the warning is cleared by pressing the SELECT wheel.

The warning messages appear in order of urgency.

The selected warning functions are active in LOCK mode and in ACTIVE mode.

COUNTRY Selecting the country

A country must be selected when switching on the receiver for the first time.

DISPLAY MODE Change the appearance of the display

The following display modes are available

MAIN

NAME GROUP/CHANNEL

DISPLAY CONTRAST

Modify the contrast of the display to the current lighting conditions

Submenu Function

FACTORY RESET Reset parameters to factory settings

INFO Call up information on the receiver software and the transmitters synchronized with it

WARNING LIST Calling up warning messages

This function saves the last 25 warning messages.

15 Maintenance and cleaning
