可選配件
The mixer power amplifier shall use digital Class-D technology with active PFC (power factor correction) circuit to achieve a power output of 120 W and shall include 4 microphone inputs and 3 auxiliary inputs and switchable 100 V (83 Ω) line, or 4 - 16 Ω low impedance outputs. It shall be equipped with a 2-channel input BUS and a signal processing function. The mixer power amplifier shall be able to connect to a PC and have the facilities for remote access and settings by using a web browser.
Inputs 1 and 2 shall be electronically balanced and selectable, offering MIC or LINE. Inputs 3 and 4 shall be fixed electronically balanced 600 Ω inputs. Inputs 1 - 4 shall have the switchable option of 24 V DC phantom power and shall be connected via a 3 pin removable terminal block. Inputs 5 and 6 shall offer either electronically balanced 600 Ω MIC inputs via a 3 pin removable terminal block, or a 10 kΩ unbalanced LINE inputs via two RCA connectors. Input 7 shall be fixed unbalanced 10 kΩ input via two RCA connectors. Power amplifier input shall also be available.
The mixer power amplifier shall have separate volume controls for each input channel and a master volume control that will adjust all input levels simultaneously.
The mixer power amplifier shall have two speaker output channels, a REC output, and two LINE outputs.
The mixer power amplifier shall have an internal chime generator with dedicated volume adjustment allowing a 1-note tone, 2-note tone or a 4-note ascending tone.
There shall be adjustable ducking facilities to decrease background music while announcements are being broadcast. The mixer power amplifier shall accommodate up to six levels of priority and via the remote control software, it shall be possible to edit the manufacturer’s standard default settings. The device shall also have an emergency priority that will broadcast at full volume even when the equipment is powered OFF and regardless of the set value of the volume controls. It shall be able to mute audio signals from the browser using manual mode.
Additional equalization parameters can be achieved via the RJ45 network terminal located on the rear panel. By accessing a web browser, status display, setting content display, input priority setting and display, remote volume, network settings, account settings, and firmware updates can also be performed.
There shall be a visual five LED output level meter and visual LED indication of internal errors, over current, thermal protection, LAN connection, emergency broadcast, priority broadcast and CPU run.
Power requirements shall be 100 - 240 V AC via a supplied power cord. The device shall have a frequency response of 50 Hz – 20 kHz with separate treble and bass controls located on the front panel.
The unit shall use 2 space units of a standard EIA component rack space and its dimensions shall be 420 (W) X 96.1 (H) X 313.1(D) mm (16.54" x 3.78" x 12.33"). Weight shall be 5 kg (11.02 lb.) and finished in black ABS resin front panel, with black surface-treated steel plate case.
