Summary of Contents for Formula Sound FF2.2

  • Page 2 Formula Sound FF2.2 Mixer Warranty The FF2.2 has a 1 year parts and labour warranty under reasonable use with the exception of moving parts. Reasonable use means operating and storage in a benign environment (0-35 degrees C and below 60% humidity, dust levels of typical home or bar /club and no contact with liquids), operating without using undue force on controls, connecting to an appropriate mains supply and connecting appropriate inputs in the power off condition.

  • Page 3: Master Section

    The FF2.2 has a flying cable with a 7 pin connector on the end, this 7 pin connector plugs into the remote power supply block, this connector needs to be plugged in to the mating connector on the remote power supply block and then the outer of the connector turned to screw the connector into place.
  • Page 4 Headphones The headphone output is on a 3 pole ¼” jack socket on the front vertical face of the FF2.2, the output will drive headphones of greater than 32 ohms impedance. The headphone controls include volume, CUE mix, split and pre/post EQ CUE selection. When CUE is selected on one of the channels or MIC then that signal will be available at the headphone control, note if multiple CUE buttons are pressed then there will be a mix of those signals selected.

  • Page 5: Input Section

    The headphone volume control sets the level at the headphone output, start with the volume set to low and establish a signal in the headphones before increasing the headphone volume. Take note of channel metering when switching CUE from one channel to another as levels may be very different on different channels and this will be reflected in the sound level at the headphone output.
  • Page 6 Turntables can be susceptible to low frequency noise, this noise consists of two types, the first is a very low frequency rumble and the second is up to 100Hz. The FF2.2 has a rumble filter to deal with very low frequency noise and a noise cancelling circuit to deal with noise up to 120Hz on the phono input.
  • Page 7 All channels have a “full kill” 4 band EQ; the EQ band frequencies are Bass up to 120Hz, Low Mid 120Hz to 800Hz, High Mid 800Hz to 4.0KHz and Treble above 4.0Khz. Variable frequency high and low pass filters Each channel has variable frequency high pass and low pass filters that are selected by a switch.
  • Page 8 Power Supply The Mixer has a fully regulated power supply that is designed to operate on 220-240Vac or 110-120Vac. Selection is by an internal switch that is accessed by removing the DAMAGE MAY RESULT IF THE UNIT IS CONNECTED TO THE WRONG SUPPLY VOLTAGE.
  • Page 9 (cap higher), switch is on when depressed (lower) and to switch it off gently press it again and it will click off. The remaining presets through the base of the unit require the FF2.2 to be active to set (booth pan, mic gain and mic EQ), so now return the FF2.2 to correct way up.
  • Page 10 0dB on the meter. Now adjust your amplifier for your required normal (0dB) sound level. If you require to pan the booth stereo image turn the FF2.2 onto its side and using a small flat bladed screwdriver adjust the booth pan control indicated by the legend on the base of the unit.
  • Page 11 Your FF2.2 is now set up and ready to go, the channel 3 input has only a volume control on the front panel and no other adjustment, note the channel 3 input has +6dB of gain so with the channel 3 volume control in middle position you are sending to master the same level as present at the input.
  • Page 12 INSTALLATION, CONNECTIONS AND GOOD WIRING PRACTICE The installation of professional audio systems should be left to experienced engineers wherever possible. The interconnection of audio systems can be fairly complex depending on the type and size of system and obviously well outside the scope of this handbook. We have included a few basic points for information for anyone who is new to audio systems.
