5.2.3Gain and Delay (Page 1)

Gain and delay are also set in the first page of the channel’s menu, providing easy access for quick adjustment during set up or performance. Note that the delay can be specified in terms of time or distance, as preferred. The unit of measurement is changed in the Set Up menu (see Section 7.6).

To set the delay

Delays can be set in seconds, metres, or feet.

Turn the centre knob slowly for step increments, or sharply to leap to the bottom/top of the range (2 or 3 sharp turns will cover the whole range). The range is 0 to 1ms in steps of 20.83 s and 1ms to 1s in steps of 0.02ms, or the equivalent in metres or feet.

To adjust the gain

Turn the right-hand knob. The range is –40dB to +12dB in steps of 0.1dB, with an OFF position just ‘below’ –40dB. Setting the gain to OFF will mute the input signal.

5.2.4Parametric Equalisation (Pages 2 to 13)

The DN9848 provides 12 parametric equalisation stages on each input channel, for equalising the input signal in respect of room/venue characteristics. Each stage can be used across the full range from 20Hz to 20kHz and is set independently via its own menu page.

To set a PEQ

1Set a centre frequency (21 steps per octave) and bandwidth (0.08 to 3 Oct) for the PEQ section, using the left and centre knobs, respectively.

2Turn the right-hand knob to set an attention/boost level in the range -18dB to +6dB. PEQ sections which are not needed in the set up should be set to 0dB attention/boost.
