The LX7-II combines the essential Soundcraft live mixer qualities with basic recording-oriented features, in a compact frame that’s
light enough for one person to carry yet easy to configure and use. This makes it especially suitable for multi-purpose use in venues
such as small halls and community centres, while its direct channel outputs make the LX7-II an ideal choice for bands who need
a live desk that can double up in the studio.

Housed in a choice of 16, 24 or 32 channel frame, LX7-II provides 24, 32 or 40 inputs - with no less than 13 separate bus outputs
including mix, 4 groups, a dedicated mono bus for centre speaker clusters, side or rear fills, and six auxiliary busses.

There are also 8, 16 or 24 direct outs, depending on the frame size of your console.

LX7-II’s balanced mic inputs all use Soundcraft new GB30 padless mic preamp providing 60dB of gain and 22dBu of headroom.
Each input also includes 4 band EQ with two swept mid frequency controls. In addition, EQ In/Out switch and steep 18dB/Octave
High Pass Filter, allow effective audio control in difficult venues whilst the six auxiliary sends are pre-post switchable in pairs from
each channel, providing a maximum of 4 pre-fader and six post-fader. This makes LX7-II equally applicable for foldback - heavy
performance or in situations where more effects are required.

LX7-II groups section houses two further stereo inputs - with EQ, auxiliaries for keyboards or stereo recording devices - as well as
two FX returns. All four groups are routable to mix and include 12 segment bargraph metering for accurate monitoring and inserts.
Six auxiliary masters on rotary controls also included AFL soloing.

In the master section there is talkback provision to all pre-fade auxiliaries and the mix. Phantom power in banks of four, and a two
track return for pre-show music are also present. A “two-track” to mix switch allows the engineer to play CD’s over the main PA
whilst back-stage set-up is going on, with one press of a button. The mix is also routable to the separate mono bus if mono PAs are
required.

LX7-II is built in a rugged wedge-shaped steel chassis with an internal power supply, professional all-metal jackfield and connectors
on the rear of the console. All inputs and outputs are balanced.

Applications incluse : Gigging Bands, Small installations, Small venues, Theatres, Houses of Worship and Live & studio recording.
