Output Type; Smartnr; Talkback; Polarity - Lectrosonics DSR4 Instruction Manual

DSR4

Output Type

Allows user to choose output for each channel, analog or
AES3.
Smart NR:
Allows user to enable Smart Noise Reduction on one
or all receiver channels. Settings are: Off, Normal and
Full. The default setting for digital compatibility modes is
"Off." The default setting for hybrid modes is "Normal."

Talkback:

Allows user to enable the Talkback (TB) function to deter-
mine where the TB outputs are routed, and to select how
the TB signals interact with the normal program audio on
those outputs. If "Off" is selected for a receiver chan-
nel, then no Talkback function will occur on that chan-
nel, even if the transmitter's programmable switch is set
to "TB" and activated. "Override" indicates that if a TB
command comes from the transmitter, then the TB audio
goes to the specified receiver output, and the normal
audio from that channel is muted. "Mix" indicates that the
TB audio and the standard audio routed to that receiver
output will be mixed to that output. "TB Only" indicates
that the normal audio routed to that output is muted, and
only the TB audio will be present, and, only when the TB
command is activated on the transmitter.

Polarity:

Allows user to set audio polarity of each channel as either
positive or negative.
Compat Modes
Allows user to set compatibility mode per receiver chan-
nel. Available modes are: mono digital modes D2 and
HDM (High Density Mode); stereo digital modes Duet
channels 1-2, and DCHX (encrypted) channels 1-2; and
mono Hybrid modes: NA Hybrid, NU Hybrid, EU Hybrid,
and JA Hybrid. EU and JA modes are not available for
Block 941.
IR & Keys Menu
The operations below depend on the compatibility mode
selected and the transmitter used. The DSR4 has two-
way IR for use with digital products (DBu, DBSM, etc.)
and one-way IR for use with older IR-capable units such
as LT and HMa. One-way protocol can only "Send Fre-
quency."
NOTE: You must position the transmitter's IR
port directly in front of the DSR4 IR port, as
closely as possible, to guarantee a successful
sync. Also see page 22 for information on front
panel sync, for bag and other close set-ups.

Send Frequency

Sends operating frequency to the transmitter, each chan-
nel separately. Press the UP button to send the Channel
1 frequency, and the DOWN button to send the Chan-
nel 2 frequency. Success for digital compat modes is
indicated on the receiver as "IR Sync OK." For digital
modes, failure will be indicated on the receiver as "IR
SYNC FAILED." For Hybrid compat modes, success will
be indicated on the transmitter as "IR SYNC." Failure
will be indicated on the transmitter as "CP Err" or "Block
Mismatch" depending on the transmitter model and the
source of the error.

Send All

(available only for digital compat modes)
Sends frequency, channel name/s, and Talkback state to
the transmitter. Press the UP button to send the informa-
tion from Channel 1, and the DOWN button to send the
information from Channel 2. Since two-way IR Sync is
only available for digital transmitters, "N/A" will be next
to any channels that are in a Hybrid compatibility mode.

Get Frequency

(available only for digital compat modes)
Send or retrieve (get) frequency from the transmitter.
Choose encryption type by pressing the UP and DOWN
buttons. Select MENU/SEL to get frequency.

Get All

(available only for digital compat modes)
Retrieve (get) transmitter's frequency, Talkback state, and
channel name. Press the UP button to get all and use for
Channel 1. Press the DOWN button to get all and use for
Channel 2. Since two-way IR Sync is only available for
digital transmitters, "N/A" will be next to any channels
that are in a Hybrid compatibility mode.

Group Sync

These functions allows you to send or get Tuning groups
via IR sync to/from transmitters and receivers capable
of using Groups (DSR4 , DCHR, DBSM, DBSMD, DPR,
DCR822, DPR-A). Use MENU/SEL button to choose the
send/get mode. Then, press MENU/SEL again and "Go"
will appear in the lower right corner. Press the DOWN
button to complete the sync operation.

Encryption Key Management

The DSR4 has four options for encryption keys:
• Universal: This is the most convenient and basic
option available, and the default setting on all
Lectrosonics D2 digital units. All encryption-
capable Lectrosonics transmitters and receiv-
ers contain the Universal key. The key does not
have to be generated in the DSR4. Simply set the
Lectrosonics encryption-capable transmitters and
