input of the
EF1210 to a level between 0 dB and 15 dB. This corresponds to a nominal playback
signal level between 0 dBu and -15 dBu, respectively. For instance, setting GAINP to
0 corresponds to a nominal playback signal level of 0 dBu, and setting GAINP to 15
corresponds to a lower nominal playback signal level of -15 dBu.
The purpose of the playback input gain is to bring the signal level of the playback
input to a constant value at the A/D inside the EF1210. For example, if we expect a -
12 dBu signal at the playback input, we would set the playback input gain to 12 dB by
sending the command GAINP12.
The playback input gain is set using EF1210 calibration procedures (See “Using the
EF1210 Without RS-232 Control” on page 38.).
The factory default setting for GAINP is 8 (-8 dBu = -10 dBV nominal level expected
at input).
Remote Commands
The following commands can be sent by the remote control device to set the playback
input gain level.
EF1210 Messages
The following messages are sent by the EF1210 in response to a GAINP? command,
or in response to any GAINP command when acknowledgment mode is on.
Example
In the following example, the remote control device requests the current playback
input gain of the EF1210 with Device ID number 7. Then it sets a new level on the
same EF1210. Acknowledgment mode is enabled.
