INTRODUCTION 3 THANK YOU!... for choosing the Manley 16 x 2 TUBE MIXER . While there are plenty of choices in low budget mixers and consoles in the $30K to $200K with a myriad of features, buttons, EQs, etc. there is very little available that simply feature sonic quality and a minimum of knobs.
1 0 4 THE BACK PANELS 1 3 4 1) MAINS ON / OFF SWITCH . "0" indicates OFF, "1" indicates ON. This should be set to OFF or O before plugging in any cables. 2) VOLTAGE LABEL (ON SERIAL STICKER) . Just check that it indicates the same voltage as is normal in your country.
5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 5) MIX BALANCED OUTPUT. Left and Right MIX outputs intended to feed a 2 track tape machine, DAT or A to D converter. These are transformer balanced Pin 2 hot. This is the mix of all 16 channels plus EXT inputs.
9) PHANTOM POWER. This switch is for the 48 volts needed for most solid state condensor mics. It is not generally needed for tube mics, dynamic mics, ribbon mics and in some cases may be harmful to some old vintage ribbon mics.
13) TAPE PLAYBACK INPUTS. Used for returning a 2 track tape machine or DAT back to the mixer for monitoring, checking or just listening. Once one records a mix, it is always a good idea to check playback. The 5 position monitor select switch on the front hast to be in the "TAPE" position to hear the playback.

9 8) AUX. Only on LINE VERSION channels. A separate mono mix that can be used as an effects send or headphone send. These are factory wired to be post fader and post cut but there are internal jumpers right next to the aux pot that allow pre fade aux or even post fade, pre cut.
10 TECHNICAL DETAILS CHANNELS: The Combi (XLR / 1/4") jack is wired to provide a 2400 ohm load for XLR sources like mics, and 82K ohms for 1/4" plugs either balanced or unbalanced. On MIC VERSIONS Phantom power can be injected with the back panel switches and uses a pair of traditional 6K8 resistors.
11 THE TUBE BOARDS The left tube board takes the mix busses through the 1K MIX GAIN pots, then a 7:1 step-up transformer. The left signal is amplified by a 25db tube voltage amp/line driver and the right signal is sent to the right tube board.
12 OPTIONS The LINE VERSION can be considered the basic root version and additional daughter boards and parts are added for the MIC and special versions or mods.
Specifications 13 Channel Input to Channel Output Frequency Response Unity Gain 10 Hz to 200 kHz -1 db Frequency Response +40 dB Gain (Mic) 5 Hz to 100 kHz -1 db THD + N Unity Gain (+4 dBu) .002% (-90 dB) THD + N Unity Gain (+28 dBu) .005% (-85 dB) THD + N +40 dB Gain .
14 ADJUSTMENTS MIX GAINS: There is a single trimmer on each tube board to set the summing amp gain. It adjusts the amount of negative feedback from a special tertiary winding on the output transformer back to the first tube stage cathodes. These trims are located near the top of each tube board, between the tubes.
There are a number of possible symptoms of something not quite right, some may be interfacing, others we will touch on as well. If you suspect a problem the following paragraphs should help. NO POWER, NO INDICATORS, NADA - Probably something to do with AC power.
IT MAKES NOISES WHEN THE FRONT PANEL IS TAPPED - An easy one. Some tubes become microphonic over time. That means they start acting like a bad microphone. Vibration has caused the supports for the little parts in the tube to loosen and now the tube is sensitive to vibration.
MAINS CONNECTIONS Your 16 x 2 MIxer has been factory set to the correct mains voltage for your country. The voltage setting is marked on the serial badge, located on the rear panel. Check that this complies with your local supply. Export units for certain markets have a moulded mains plug fitted to comply with local re- quirements.
