Express IP MINI – 2 Speakers Table

Two Four Wire Circuits

The Express ip Mini has two talkback circuits. Each speaker has their own talkback buttons. The push buttons for each circuit feature Config. and as such are configurable and can operate in different modes:
– Latching on/off
– Momentary push to talk (PTT)
– Intelligent mode where a short tap is latching, but a longer hold becomes momentary
– Always on and mutes when pressed (cough mode)

Pressing a talkback button removes the mic from the main output and directs it to the talkback output.

Headphone Monitoring

There are 4 inputs into the headphone mixer. Each speaker has individual pots to set their preferred mix of these sources. There is a 5th pot for adjusting the level of the speaker’s own voice (sidetone) and a 6th pot for adjusting the level of the other speaker’s voice in their headphones.

The front panel has 2 x 6.35mm jack sockets for connecting the speaker’s headphones.

Mic Inputs

Both mic inputs are on the front panel 3 pin XLR connections. The input is switchable to add 48V phantom.

Each speaker has a mic on/off button that can also be configured to be always on, muting the input when held down (cough button).

Mic Gains

Two front panel rotary controls can be used for adjusting the microphone amplifiers input gain by +10/-20 dB. The lineup gain of the microphone amplifier automatically reduces by 10dB when the phantom power switch is turned on.

Compressor Limiter Circuits

Each microphone input has its own compressor/ limiter circuit to prevent audio overload by an excited speaker.

Network Audio Link

The Express ip MINI is Dante®/ AES67 network audio compatible. The network connection is via a single EtherCON RJ45. This link carries:
– 4 audio inputs
– 4 audio outputs
– Power over Ethernet (PoE)

The four audio outputs that go into the Dante network are:
– Talkback 1
– Talkback 2
– Mic 1
– Mic 2 or Mix

The 4th output ‘Mic 2 or Mix’,  can be selected via a rear panel switch to be the direct B mic, or a mix of both the A and B mics.

PPM Meter

There is a seven segment PPM meter that shows the mix output level as both dBu and BBC PPM 1 – 7 scale.

Power

The Express ip MINI is powered over Ethernet PoE and can be connected to PoE enabled switches and midspan power sources.
