qf OUTPUT fader

You can adjust the OUTPUT fader by dragging the fader portion.

The yellow marker displayed on the side of the fader indicates the fader position that is the addition of the OUTPUT fader setup. When the sound volume of a specific input channel is to be set from the REMOTE screen and the GROUP FADER screen, the fader position determined by the SRP-X700P Master volume control and the remote control signal via the REMOTE terminal is indicated.

(The fader level at the yellow marker position in Fig. 2 is the

–15 dB position.)

qg REC OUT index

Displays the index that is entered on the BLOCK screen.

qh REC OUT level meter

Displays the output signal level using the VU response.

qj REC OUT REF LEVEL selection box

You can set the reference output level for every output channel on this selection box.

You can select –10, –5 or 0 dBu as the REC OUT level.

qk REC OUT MUTING button

Mutes output signals of the respective channels. The REC OUT MUTING button lights in red when muted.

Power Amplifier Block

ql Operation mode setup box

Selects one of the following modes depending on the type of speaker to be connected.

Lo Imp.: A low impedance (4 Ω to 16 Ω) speaker is to be connected.

70 V LINE: A high impedance (32 Ω to 10 kΩ) speaker is to be connected.

In the case of 70 V LINE, the channel 1 setup becomes valid for the selectors and attenuators.

w; PROTECTION indicator

The PROTECTION indicator lights in red when the internal power amplifier protection circuit operates.

Note

When the PROTECTION indicator lights

The protection circuit operates (PROTECTION indicator lights) and the speaker and amplifier are protected from damage by decreasing or cutting the output signal in case of the following:

•If the temperature of the heat sink inside the amplifier exceeds the specified value.

The connected speaker impedance is too low.

Air intake and air exhaust holes (on the right and left sides of the SRP-X700P) are choked by dust.

•The SPEAKER terminal is short-circuited.

In such a case, turn the POWER switch to the OFF position and remove the cause of the fault before using the unit again.

•If DC voltage appears in the SPEAKER terminal due to failure. Turn off the POWER switch and contact your Sony representative where you purchased the unit or contact your local Sony Sales office or Dealer.

wa SPEAKER OUTPUT index

Displays the index that is entered on the BLOCK screen.

ws SELECT setup box

Selects the input signal to the internal power amplifier. When the 70V LINE is selected, the channel 1 setup only is valid.

wd ATT

Adjusts the output level for the internal power amplifier. Clicking the [+] or [--]button increases or decreases the output level in the range of 0 dB to ∞ dB. When the 70 V LINE is selected, you can adjust channel 1 only. ATT is set at the

10 dB position for ordinary use.

wf SPEAKER OUTPUT MUTING button

Mutes the speaker output. The SPEAKER OUTPUT MUTING button lights in red when muted. When the 70V LINE is selected, the channel 1 only can be operated.

wg CLIP indicator

The CLIP indicator lights in red when the internal power amplifier clips. Adjust the output level using wd ATT so that the CLIP indicator does not light frequently.
