Alice 828 Mixer Mk3

The 828 series mixer went into production at the Alice factory in Windsor in 1976 and the last one was made there in 1986. The Mk3 was designed by Ted Fletcher in 2019/20 with production starting in August 2021. It only took 43 years for the MK3 version to be made!

As well as the standard gun metal gray, we have made 10 limited edition versions with relays on all three mic channels as standard. They are available in 5 colours: Chilli Red, Tango Orange, Midnight Blue, Kawasaki Green & Banana Yellow. Microphone and mono line inputs & line outputs are transformer balanced. Three x microphone inputs c/w 48v phantom powering. Five x stereo line inputs (with two having line/RiAA amplification as standard). Microphone position one has monitor cut and a remote control relay via the 9 pin D-Sub.

The ALICE 828 Mk3 is available in three standard models:
1. 828 – 3 mono mic/line inputs, 5 stereo line channels (2 with RIAA preamplifiers), 2 output groups, VU meters,fader electronic microswitch for L.S. mute on channel
2. 828-8 – 8 mono mic/line channels, 2 output groups,VU meters.
3. 828-12 – 12 mono mic/line inputs, 2 output groups,VU meters.

Mono/Mic -Line Channels
Each mono channel has two inputs, both are transformer balanced.
The mic input is a standard 3-pole XLR female socket (pin 1 ground, 2 hot & 3 cold signal), and the line input is high impedance balanced via a standard 1/4″
(6.35mm) 3-pole jack socket.
A push-button switch selects the required input, and the continuously variable rotary gain control has arange of 50dB on mic. and 24dB on line.
The equaliser has HF and LF boost and cut and a very useful MF section which allows the frequency of a boost or cut to be varied over a wide range (see
SPECIFICATION). A push-button switch allows the equaliser section to be completely by-passed if required.

Stereo Line Channels
The 828 stereo channel is a dual-purpose design, incorporating a compact RIAA stereo pre-amplifier section on stereo channels 4 and 5. This is accessed by phono sockets, allowing a magnetic phono cartridge to be connected directly into the mixer. Two mono jack socketsare provided on each stereo channel givingaccess to the channel at line level, this latter is wired through break contacts in the jacks so that
connecting a line level signal disconnects the pre-amplifier (on channels 4 and 5).
On stereo channels 1, 2 and 3 the lower jack socket switches to ‘mono’ when there is no connection into the upper socket.
The continuously variable rotary input gain control has a useable range of approximately 24dB; the two auxiliary outputs are mono derived.
The balance control has a range of ±6dB; the channel has mono derived PFL and a stereo fader.

Groups
The two output groups each have a line level input via a rotary gain control, designated ‘aux in L & R’.
Each group has a simple but extremely effective peak limiter, with individual threshold and ‘on’ controls, and status indicating LEDs.
Two auxiliary outputs are provided, one pre-fader (aux 1) and one post (aux 2). The output master send controls are above the group faders. The left group carries the master aux 1 control, and the right group the master aux 2.
A pan-pot allows each channel to be adjusted in a stereo mode between the two output groups, and a latching push-button switch connects the pre-fader
channel signal to the monitor section. The 60mm conductive plastic track fader is fitted on channel 1 with an electronically controlled microswitch for activation of muting systems, red lights etc.A mono post-fader direct line output is available on a standard 1/4″ (6.35mm) 2-pole j
