d&b Yi7P - Manual (Page 5)

2.1. Product description
The Yi7P/Yi10P are passive 2-way loudspeakers housing two 8" LF
drivers and a 1.4" HF compression driver with a rotatable CD horn
producing a nominal dispersion (h x v) of 75° x 40° or 110° x
40°, respectively. The frequency response extends from 59 Hz to
above 18 kHz.
The two 8" neodymium LF drivers are positioned in a dipolar
arrangement providing exceptional vertical dispersion control even
at lower frequencies.
Specially designed ports with optimized flow characteristics
provide a considerably improved, efficient low frequency
reproduction.
The top and bottom panels of the cabinets are each equipped with
a pair of M10 threaded inserts to connect to different rigging
accessories such as the Z5398 YP Horizontal bracket, the Z5399
YP Mounting bracket, the Z5354 E8/E12 Flying adapter or the
Z5020/25 Flying adapter 02/03.
2.2. Connections
The cabinets are fitted with a pair of NL4 M connectors and a two
pole screw terminal block (ST). All four pins of both NL4 M
connectors are wired in parallel. The cabinets use the pin
assignments 1+/1–. Pins 2+/2– are designated to active
subwoofers.

Fixed cable connection
The Yi7P and Yi10P loudspeakers are each supplied with a cover
plate [1] and a rubber grommet feed through [2]. For indoor
operation, these items can be used to hide the connector panel, if
required. For unprotected outdoor operation, the connector panel
must be covered, i.e. both items must be used to achieve an IP
degree of protection of IP34.
