Input Pad
fig.6-42.eps
Each S-1608/S-0816 system’s input channel features a switchable
input pad. When the pad is engaged, the channel’s input sensitivity is
reduced by 20 dB.
Use the pad when connecting a “hot” audio source to an S-1608/S-
0816 system’s input—one whose signal exceeds 0 dB (and causes the
clip indicator to light) even when the channel’s [GAIN] knob is at its
lowest setting.
Use the following procedure to engage the input pad on a particular channel:
1. Select the desired channel (1–24) with the [CHANNEL] knob.
2. Press [PAD] so its indicator lights.
3. Repeat Steps 1-2 to engage the input pad on other channels.
To turn off a pad, select the channel with the [CHANNEL] knob, and then press [PAD] so its indicator
goes out.
Phantom Power
Each of the S-1608/S-0816 system’s inputs can supply +48 V phantom power to devices that require
it, such as condenser microphones or active direct boxes.
fig.6-43.eps
Use the following procedure to turn on phantom power on a particular
channel:
1. Select the desired channel (1–24) with the [CHANNEL] knob.
2. Press [PHANTOM +48 V] so its indicator lights.
3. Repeat Steps 1-2 to turn on other channels’ phantom power.
To turn off a channel’s phantom power, select the channel with the [CHANNEL] knob, and then press
[PHANTOM +48 V] so its indicator goes out.
While a channel’s input pad setting (on/off) is changed, its output is temporarily muted to avoid noise.
Always turn the phantom power off when connecting any device other than condenser microphones
that require phantom power. You risk causing damage if you mistakenly supply phantom power to
dynamic microphones, audio playback devices, or other devices that don’t require such power. Be
sure to check the specifications of any microphone you intend to use by referring to the manual that
came with it. (This instrument’s phantom power: 48 V DC, 14 mA Max.)
While a channel’s phantom power setting (on/off) is changed, its output is temporarily muted to avoid
noise.
